Love how he says to wear a face shield and gloves while not wearing gloves, and I'm assuming hes not wearing his recommended face shield either lol nice
no i was not ..and i even smelled the stuff that came out of it by accident and said " wow that smells sweet" but took that part out =P .. actually i did have on face protection but not a full face respirator mask other wise i would of had to dub in the audio ..Which really i guess i should of its not like you actually see me talking.
your welcome..usually you can use your charger to discharge as well if you have that option . However mine gets really hot as its just a resister I believe.. thanks for taking time to leave a comment..
Interesting video. I am just wondering why did you remove the insulation at first then puncture the battery shell. What is the danger of piercing a hole without removing the shell. A small hole with a needle is more than enough to get the air out. Any comments appreciated. Thanks
Hi on the table you can see I have a small needle . I was more worried about showing using a needle because if you push too hard it will short out some cells. It will work anything that can break through the layer will work. Personally as i said in my description , I should of used a sharp piece of plastic to create the hole. Its really what you feel safe using as well. I didn't go through the shell because again its about control. But No reason why you can't if you take your time and feel comfortable doing it. also we don't know if part of the cell layers are stuck at the top of the puffed up battery as well. A month after the video one of my viewers made a video using a needle. and he has no problem doing it. But again just take your time and stay safe.
Thanks for taking the time to make this video. Certainly interesting to me and great to see - in your last comment - that the batteries have continued to work fine. I'd love an update on if they continued to work long term after you released the gas?
@@rameezbenjamin2677 I released the gas from two of my packs (they came with 2x cars for the kids and I needed them to work so took the risk) anyway they worked perfectly and still do 6 months later!
How long did it run after this? I did something similar as an experiment with 2 puffed lipo's but didn't cover the hole and they died withing days. I assume the oxygen getting in oxidizes the lithium, but seeing you squeezing the gas out, i think each time you stop some air gets sucked in anyhow, so even if its sealed within maybe weeks it will completely die or puffen up again. My take on it is if the hole its made on one end and you squeeze from the opposite towards it continuously and just before you stop you place the tape over it will prevent any air getting in when you stop.
I've had really good luck with them.. maybe its the tape i'm using seals the hole really good. I've done lots of those little ones as well that seem to love to puff up.. . I also charge them at half c now instead of at c or double c .. lol I was thinking of using epoxy .. but I don't want to be mixing chemicals on something I'm truly not knowledgeable on . And so far using the duct metal tape and electrical tape over top has been working .
I found that Contractors Solvent or Goof Off applied with a dropper or syringe between the cells softens the adhesive so they come apart with a minimum of force. What you did to pry apart the cells can rip the plastic cell envelope.
it should say the c on the battery.. I just ordered a diode jumper clamps/booster clamps . to basically do what your asking .. it can do max c and beyond for only couple of seconds ..and you will get puffin of the battery if any longer, plates will separate ..
I should note trying to achieve max c can be dangerous is no different in some cases of shorting out the battery .. but keep in mind the battery booster packs for cars that cost 200-500 dollars have a smaller lipo and still get 500 or more amps out of them, the only difference is they have mosfets that limit the battery to only couple of seconds of full amperage .
hi i've never had a issue re charging them..but not say its not dangerous .I do charge them at about 700ma-1amp now.. I use to charge them at 5 amps / 1c for what ever the battery is meant for so a 2400ma battery i would charge at 2.4amps ect.. One video i found said the puffing is when 2 plates separate and that causes the puffing. However I have found other videos or pages that say its cause from the charging process and gas is a by product from heat . I'm really wondering if its more on how these battery's are just rushed and not sealed up extremely tight. As they just build ship and sell with no worry of lawsuits like phone battery's where it can totally hurt a company with defectively wrapped battery's as they have to be really squished up tight in the silver package... anyways if you can order a new one and chuck it or gamble like I do but thats on you. Good luck which ever way you go.. stay safe and happy Rc ing..
is it a good idea to make a homemade sky lantern that can fly off into a forest and catch 1000's of homes on fire?? I don't think so. =P .. but yes you are right its not the best idea to puncture a lipo battery . but for me it works. And if you can get replacement battery's in your country easily I would not suggest this at all..
Removing gases from a battery by punturing it can make the battery just looks good as new for your satisfaction but later on after a few uses it's power will gradually decrease means it drains so fast and finally one day it will be completely dead, i am saying this as per my experience because something like this happend with me. One of my 3s lipo battery was puntured during crash and i reapired this way but after some day that complety dead. BDW, where i was flying sky lanterns there are no homes and dry forest and that time the season was monsoon, i am always aware about those things..... so don't imagine be practical.
@@niharranjanmahali8549 its been 11 months and all my battery's are still good.. However i no longer charge them at 1c or 2c . that's what actually creates the extra oxygen in the battery's . This is not the same as your crash example as this is releasing the oxygen nothing more. Unless you puncture through some plates and short them. My example of the lanterns, just because you do it safe does not mean one of your viewers will and they may burn down a village . However I didn't go to your channel and post that !.. I just found it ironic your first comment to me thats all.. . Your second comment at least you explained your thoughts on it , Even though your example is nothing about the extra oxygen and your just guessing what would happen to them . I did it and i know it works for a fact with nothing negative on the battery as all i did was released the oxygen on all my bloated battery's, If it didn't work , my channel is not about lying to people, all my mod video's are done in real time and if it does not work out I would post it didn't work . Or make a update video on it. Also i would rather release the oxygen in the battery in a control fashion then having it crash and puncture and release it all at once around electric circuits that are most likely shorted from the crash. This is not about looks or making them look pretty for my satisfaction at all its about getting rid of the extra gas. But again the best thing to do is throw it away and get the bloated battery out of your house . I don't care about people posting this and that about it being dangerous but I live in facts And i know for a fact that this worked because i actually did it on over 20 battery's of all sizes, with no loss of energy that just not make any sense that would happen.
oh btw I was looking into making lanterns about 2 moths ago I forgot all about them so I will be checking out your vids specially if you have a step by step on how to make them.. but i really do live in a country that has no outside fires during the summer months but would be nice to make in the winter..
Relax man, you wrote a passge?? 😆 I gone crazy when i saw this bunch of text. I am not saying you wrong and i respect your channel, what i said that was just my personal experience so forget those things, your videos may be is helpful to me and others. Anyway, after all if you forgot our previous conversation then now as a good friend honestly i want to ask you one question, so the question is i have a 3s lipo battery (not much used) which was started popping last year and now that is popped too much on both sides but it's working fine and all cell's internal resistance is also good(between 5- 7 m.ohm) so sometimes i feel afraid that this is gonna explode if get popped little more, so what you think about it, let me know.
You highly can damage cell cover with this knife method you did on video sir. Small needle can work better. I prefer cut the cell out and put there a healhty one. Anyways thanks for video.
@@jamesjay1987 yes like my above comment I should of used plastic or a piece of glass .. my first idea was to use the small needle you can see that on my board lol.. ..but was too nervous going through two layers.
Hi thanks for your comment and concern , Yes it would be simple but also dangerous in the wrong hands making it into a 2s battery.. I urge all to get a new battery if possible .The video is basically just showing that I finally got sick of everybody saying to throw them away because they are bad. In Rc and quad copters its usually just due to charging them or discharging them too fast. and none of the cells are actually bad. I have both battery's that were shown in the video and they both still work. I'm comfortable doing this Now.. I've seen lots of video's of others showing how to take a 3s battery completely apart as well. ElectrocBOOM made a video with probably close to 2 million views how to melt stuff with a microwave transformer. Now that is my limit and I would not feel comfortable showing or using something like that. Each to our own on our comfort levels.. But I'm also not going to post on his video to just buy some Bolt cutters.. .. but with all that you were not rude at all , you were pointing out the risks and a easier solution to something that can be dangerous.. .. So really thanks for the comment..
Dude, What were the police responding to in the background I could hear them almost through the hole video, what type of plastic scraper would you use? If I ever attempt this I’m gonna wear flame retardant gloves and safety glasses. I had one go up in flames once while unsoldering the puffed up lipo. Keep up the great video work.
maybe smashing a old dvd / cd case ..those come up pretty pointy at times.With plastic you have to wiggle it back and forth instead of scrapping and pulling up words..... That must of been scary having it go off right in front of u......Yeah if you do to it, Make sure its outside away from buildings, be safe.. I live about 10 mins away from our city's main hospital so it might of been that. I find the helicopter more annoying now as that noise can make it into my house even with the windows closed..
@@ModItBetter thanks, it was scary, but it was mostly a smoke show. I used my water bottle to distinguish the smoke. No when I do any work to a lipo like changing out corroded balance leads or swapping out an old plug, I keep a cup or two of water next me just in case, I usually do it outside unless it's too cold, outside. Do you think silicone sealant will work for sealing up the lipo? Along with electrical tape? I have aquarium safe silicone.
@@calebsrccrawlers it might be safe.. but i don't know if the chemicals would interfere with each other if it got inside.. sooooooo maybe cut a really small square of electrical tape place it over hole.. then put the silicone over the tape and the sides of it then tape over that...not sure if silicone would stick though to either material as well.. I just looked on amazon and the metal foil tape(hvac) i used in the video you can get a role as cheap as 7 dollars Canadian..But really I only used that because its so sticky can handle heat and ages well...Maye the ones for 7 bucks on amazon are not sticky at all.. .. .. .Probably any kind of good 3m tape.... ..But if you try the silicon let me know how it goes and how it sticks.. All i know is electrical tape on its own is worthless as it ages..
That first round was agonizingly sketchy. As for cell separation..I used a credit card by slowly pushing it and rocking it back and forth between the cells. Worked really well you just have to be steady firm and slow ....with patience
Actually bro I will throw my lipo out and never do such things even if it will cost me a 1000$ loosing an eye or a finger worth billions to me, god bless you and be safe while working with explosives
Oh no doubt and god bless you as well. .If you don't feel comfortable doing something no doubt don't do it.. millions of videos on youtube about chemicals ..like nilered for instance they all play with Concentrated Nitric Acid .. and i would never do it.. .. this video was more a proof in theory.. Honestly its not that scary at all to me anymore but I would still strongly suggest buying new over doing this if you can. ..Regardless thanks for your feedback..
agreed it does not "fix" a bad cell or make you pancakes in the morning.. but it does release the gas out so you can fit it back in tight spaces.. The only true fix for a bad cell is getting a new cell. Also changing the amps you charge the cells and discharge is usually Key buttttt the people that design our products go for the smallest battery's for weight and the fastest discharge to keep our quads ect in the air.
hey im trying to repair my mouse i took the battery out and i think it is punctured, im not sure if the smell is the glue or the battery is it like a sweet smell/chemical or something ells?
.edit... Most likely it is the battery, it smells fruity .. It is possible it is the glue but doubtful.. You might of punctured it while trying to pry the mouse case off with a screwdriver ect..??.. To be safe i would get the battery out of your house... Take note of the cell numbers 3.7v ect.. .. Also if the battery has a plug on the end you might want to cut one lead at a time to save that end so you can just replace the battery with another cell . If it does not have a connector at the end but is soldered in place.. cut one lead at a time close to the battery so you can twist on the leads from the new battery . Or if you can solder just desolder it.. If you post a link to what the battery looks like . I can probably help you find a replacement if your un sure about that. (Leave another comment saying you posted a link though as a rarely check my flag comments with links) the battery might of been puffed up already and all you did was released the gas from it by accident. However because you did not do it in a control way ,you wont know if you bent some plates and can potentially short out at anytime. So its a pretty big gamble to keep using it. Or I'm wrong and it is the glue.
I have a 24s that uses a bms... I've clearly got some puffy cells and my bms cuts them off the rest of my battery... but I wonder if the puffy cells will damage the surrounding cells and spread the damage if I dont remove the puffy cell??? Any suggestions?
it really depends on your setup if its in a tight container it can squish other cells but doubtful it would do damage. I would be more concerned of the cells releasing all the gas at once / bursting (which to this day i've never seen it actually happen) Personally i would either remove them or release the gas in a control setting . If your management system is ignoring the cells that are bad.. is a good thing but might be a bad thing long term as well .?? .. If you do release the gas you might have to wake the battery back up with a very small current for 20 or so hours on another lithium charger( 100ma or bellow) ..Your bms might of let them get way bellow the safe spot for the battery .. Personally if your bms is saying its bad, get rid of it ..as they can't detect bloated battery's and all the ones I have come across charge fine during and after I release the gas. If your getting lots of bloated battery's I would look at the charging rate or the discharge rate of why its happening .. unless you know and this is just the cost of your setup.
@@ModItBetter thanks... I'm performing surgery on my pack as we speak as we speak... I'll have to decide if I should remove the damaged cells and run less in series but then I'll need to replace my bms too I believe for the correct number of series, or replace the damaged cells with identical cells... or I'm considering trying to release the gas out of the damaged cells and then rebuild the pack... we will see how it goes, I've got the heat shrink all off... why is this fun idk but it is lol although it would be more fun if it wasn't a $400 battery
@@MotoAlias well hopefully it works out .. if you are going to release the gas.. just really think of all the worst outcomes specially if its attached some how to many other battery's.. As allways do it away from any buildings wear the proper safety equipment take your time .. really pulling the cell that is glued to another one to me is just as much or more dangerous ..because you can actually bend the cell past its limit . Be safe and good luck with which ever way you decide to go..
@@ModItBetter hey friend if my swollen cells are showing zero volts then is releasing the gas kind of pointless. Or if I release the gas I've gotta then wake them up somehow??? I'm on the hint for replacement cells but they're not easy to find
I don't see how that cell has been fixed, what I would say is the cell has had the puffiness removed, but the internal problem with the cell still remains, which could make the cell less stable.
@@ModItBetter It could yes but it's not inevitable, I believe that only happens when the cell shorts out either due to the dendrites or perhaps impact maybe even over charging. But you were wise to be careful doing what you did.
it can be from a bad charger .. charging at too many amps.. could be what ever you used it for, drains it too fast.. And extremely possible its just defective.. If you have a balance charger that can view the charging of each cell be helpful .. one cell might at its max and the rest are still low . if its a multi cell (2cell ,3cell,4cell) ect.. If its a one cell those guys love to puff up from to much amps during charging ..
The #1 most common cause is letting them sit around fully charged for long periods of time. That will ruin a lipo quickly. Get a charger that has a storage charge setting. Always storage charge the lipo when you are done for the day. They will last much longer. A fully charged lipo will be 4.2v per cell. Storage charge is 3.8v per cell. If you have a puffy cell, hook it up to a light bulb or spare motor or other small load, and run it *completely* dead, then dispose of it. A puffy cell is a ruined cell.
Hi .. I just pulled them out,, I have not used them for about 8 months.. .. The first pack from the video are 3.82 * 3.83 * 3.85 so a tad off but not bad.. the second battery was puffy again just Now..9/7/2021 buttttt That means using the electrical tape and the metal tape actually worked.. I just simply peeled the tapes back and released the gas again. .. This one i would have to discharge i think before charging again.. its sitting at 4.2 * 3.8 * 3.87 ..If i remember right I got that one from banggood and one cell was always off from the start.. and the cell would over charge from 4.2 but that was 2-3 years ago.. its actually sitting at 12.6 so maybe later today or tomorrow i will discharge again and see how many amps it can hold again. Does not seem right to be at 12.6 volts after 8 or so months..(also if you add up the cells it does not = 12.6 anyways ..) i was using the second to fly my quad again its been awhile because of restrictions .. the First one i had screwed up in the video I use with a dc to ac converter for when the power goes out to power my network Modem.routers for..phone /voip ect.. Anyways I took them both off the charger and will try to discharge them in the next couple of days and give them a full charge again to see what state they are really in.
If the hole is sealed up really tight i'm not sure how it would.. its been 4 months now and I did about 12 diff style battery's.. .. So explain why it would later on! condensation if the tape failed?.. The hole is about the size of a pin head. so maybe seal it with something else beside 2 different style tapes? Like maybe really small piece of tape then epoxy over the tape?? I'm not trying to argue but instead of saying something won't work ,Explain why so maybe we can over come what your issue would be.
@@ModItBetter It’s gonna fail one way or another never bother explaining Some’s answers are based on fear mongering knowledge given from the news and other media outlets. Just can’t win em all
@@ModItBetter what would happen if the hole is not shut? Would it degrade or would it catch on fire?why wouldn't manufacturers design these with somewhat of a valve to expell gases.?
@@rousdiandraos4397 I believe Lithium can possibly catch on fire if too much moisture is able to find its way inside . A release valve would be ok with a warning to only vent out side ect.. however if it was a release valve that automatically releases it all at a certain pressure it could be extremely dangerous if it was around something flammable .
@@ModItBetter the release valve is exactly the satchel. That's why it's in negative pressure to give the space when it react to the high discharge its inflates to release the pressure without escape the hydrogen and avoiding risk of fire.
cell is bad already once they puff i dont get why risk it ..my friend had puff packs and poke a hole and kept using it and it caught fire on the charger almost burn his house down...why risk it for couple packs 100 bucks or so just buy new ones aint worth burning down your home or hurting yourself
Hi thanks for your comment you are correct its easier and way way safer to get a new one.. If your battery is swelling extremely fast not over a year type thing.. then I would look at the charging system or how your using the battery you/he might of been drawing just too many amps or charging it too fast when he needed to put another one in for his purpose .. Personally it sounds in his case to be a charging system fault as it should of caught the problem instead of continuing to feed it more ,My guess his charger over charged it.
omg dude! stop swinging that box cutter like it were a machete! You could have damaged any of the cells at any moment! Also WTF electrical tape! USE KAPTON!
Kapton tape to wrap the battery when done?.. the only tape that concerned me was the tape that sealed the hole.. the electrical tape is just for a tight wrap.. Kapton tape for a wrap? Every time i get any sort of heat resistance tape its not sticky or stretchy .. Regardless thanks for suggestion , however if you make a video wrapping the battery with Kapton tape .. I'll be sure to post WTF why not use the larger heat shrink tubes to wrap the battery properly =P ..oops I'll also make sure to do it in caps ..
ah maybe your talking about 23:39 ..i just used electrical tape to shield it from the better metal tape.. yeah Kapton tape or a piece of plastic or anything would of done the same thing .. i do have tons of heat resistance tape .. Curious why do you think that would be better to seal the hole then electrical tape?
Anddddd your right about the knife in my description I added, I should of used a sharp piece of plastic instead of something metal.. So 100 percent agree with you on that one..
@@ModItBetter Use kapton to seal the hole. (also next time use a pin, the smalled the hole the easier it is to seal it air tight). You could also use it to bind the cells together but think notmal scotch tape is more than good enough. Electrical tape rots, it wont hold the seal for too long, 1 or 2 years at most, thats why use kapton which is heat resistant and the glue wont rot or dry after the years. The only downside with kapton is that its really sensitive to grease, so the smallest amount of grease on the surface or your hands will stop it from sticking, so clean everything with alcohol first, wash your hands, then make a tiny hole without touching the surface around it (use globes or a clean plastic sheet to push the gasses out) and then apply the kapton tape and make sure to push it tight. (use the edge of a credit card or some plastic piece and scrape the surface of the tape until you see all the surface take a darker color, that means theres no air bubbles and the glue is making full contact with the surface of the battery) Kapton does stick but like i said its really finicky about grease. Also it does strick but very little. I use it to tighten the glass fiber isolation around the heater in my printers and even at 250ºC it doesnt come apart, so its all about knowing how to use it. A trick with kapton is to cut the piece longer than what you need so that you have room to grab it, stick the clean section, and then cut the ends with scissors or a surgical knife (they are really handy) which wouldnt stick because you touched it with your hands.
@@laharl2k Thanks for the detailed explanation on how to use kapton tape.. I'll use it on the next battery .. keep in mind i still seal it with way better tape over it.. but the tips you gave will be handy , I really only use it for re flow or removal to protect other components .
yeah but be careful on the word "fixable" as I found out a few comments back. lol.. This wont fix a bad cell but will let you fit your battery back in its compartment.. anyways thanks for leaving a comment..
Really there was no point pulling it apart like that just put a hole in it, you simply remove the outer heat shrink and put a pinhole in it then squash the air out then seal the hole, apply heat shrink and your done...
yes as I point that out at 0:45 , Also i had a pin on the table.. i changed my mind on that as I didn't want anybody going through 2 layers and shorting out the battery but it does work do what ever your comfortable with . Keep in mind this was a first and second attempt video and not a true step by step ..
This advice is Very bad. DON'T MESS WITH BLOWN BATTERIES, JUST DISPOSE OF THEM. I get the horrors you using a knife to open a Lipo battery. Your viewers should NOT do this!
do you really think your the first person to comment that after 2 years? as i said so many times do what your comfortable doing .. Personally disposing of them is best. However I did not die and the battery's are still working till this day.. electroboom has over a million views showing how to melt a lock with a microwave transformer.. please go to his page and post the dangers as well.. ty... Ps ..the batteries in this video were not BLOWN they were BLOATED, If they were damaged from a internal short they would not charge normally and most likely would of BLOWN up once it happen.. .. .. HUGE difference HUGEEEEEE.. But once again .. Yes dispose of the batteries is always wise. Just having any lipo battery in your house is actually dangerous..
So let me get this straight, Every day a quadcopter loses signal and crashes. You feel 100% safe flying your quadcopter over a busy highway with thousands of innocent people!!!!, maybe even someone coming home from the hospital with a newborn!. Or flying over forests with the risk of starting a forest fire from crashing. How dare you show your viewers to be so irresponsible!!!!!! Especially over a highway. It's people like you that made us have to get licenses to fly them. Thanks!!!!" but your right it only takes one, Again replace the batteries if need be, I simply showed that even I was nervous about it because all the people in the echo chamber repeating how dangerous a bloated battery is.
You cannot fix A battery one’s it is swollen ! You have to buy a new one if you try to fix it Lipo batteries are very dangerous you’ll be better off recycling it even though rumors that you can fix a swollen battery You can’t !
I appreciate your concern for safety when it comes to dealing with swollen batteries. However, I respectfully disagree with your opinion that it's impossible to fix a swollen battery. There are actually some safe and effective ways to attempt to fix them, depending on the type of battery and the extent of the swelling. That being said, it's always important to take proper precautions and consult with a professional before attempting any DIY solutions. In some cases, it may indeed be safer and more practical to simply recycle the battery and invest in a new one. Ultimately, the decision depends on individual circumstances and preferences.
oh and the one i had taped up I actually use with 5 volt bec and powered my heated sweater all winter.. hmm i don't recall running around on fire..but you could be right..
@@dummkompf its not a short though.. they usually puff up from heat bad charging style .. Like on some of mine I would charge at 10 amps 2c .. or bad discharging too quick like most of our quads can deplete full charged battery in about 10-12 mins . If it was internal short it would catch on fire.
Lipo’s swell because they are damaged doing this is both stupid and dangerous! Its gonna swell again and possibly catch fire the price of a new battery is not worth it! These videos should be banned
if they were damage they would catch fire.. uģgg. to stop the swelling put less stress on them ... i no longer charge at 2c and I charge them lower then 1c.. both battery's still going strong...
but u are right replacing them is best however ..i madr the video because of ppl like you that just repeat what other people have said with out actually trying
@@jameshankssr466 Okay Karen, chill tfo. He clearly states all the dangers and recommends doing at your own risk or buying a new battery. Stop trying to ban everything you don't agree with. Are you a battery engineer? Did you learn to throw away puffed lipos from a CZcams vid? You had to have learned it from someone or somewhere. Learning is good. Have you repaired batteries before? Have you gotten hurt? Do you even know how to solder? I don't know you and I don't know what your backgrounds are so take it for what it is. Batteries catch on fire even when they aren't "puffed". What you say is clearly safety recommendations, regurgitated from the internet, and there are many ways to skin a cat.
@@87VNP Something tells me that most likely such "fix" will make battery capacity decrease with every charge / discharge cycle because air would be able to make it in through the tape, and then it will react with electrolyte components over time oxidizing things and reducing the amount of electrolyte available for charge storage.
I'm really glad you showed that you discharged before attempting. The higher the charge, the larger the flame
thanks Anderxale .. And thanks for pointing out another mistake i did in this video .. I did not explain why I had discharged the battery...
Ya for real u the man scary

Interesting video. I am just wondering why did you remove the insulation at first then puncture the battery shell.
What is the danger of piercing a hole without removing the shell. A small hole with a needle is more than enough to get the air out. Any comments appreciated. Thanks

Thanks for taking the time to make this video. Certainly interesting to me and great to see - in your last comment - that the batteries have continued to work fine. I'd love an update on if they continued to work long term after you released the gas?
If i remember I'll come back in june 2021 and post how much current they still have ect....
Would also like to see if they work still very well after that
@@rameezbenjamin2677 I released the gas from two of my packs (they came with 2x cars for the kids and I needed them to work so took the risk) anyway they worked perfectly and still do 6 months later!

I've had really good luck with them.. maybe its the tape i'm using seals the hole really good. I've done lots of those little ones as well that seem to love to puff up..
. I also charge them at half c now instead of at c or double c .. lol
I was thinking of using epoxy .. but I don't want to be mixing chemicals on something I'm truly not knowledgeable on . And so far using the duct metal tape and electrical tape over top has been working .
I used a pin for the hole and sealed it with double duct tape and it works fine 5 months later
Thats great sir
I found that Contractors Solvent or Goof Off applied with a dropper or syringe between the cells softens the adhesive so they come apart with a minimum of force. What you did to pry apart the cells can rip the plastic cell envelope.
and bend the hell of it .. thanks for the tip on the goof off.. next time i need to build a 4 or 3 cell out of bad battery packs i'll give that a shot
JUST POKE A HOLE IN IT ALREADY!
Thanks for the testing. You charge them with about 0.2c. What is discharge current? Is it possible up to 30c or higher?
it should say the c on the battery.. I just ordered a diode jumper clamps/booster clamps . to basically do what your asking .. it can do max c and beyond for only couple of seconds ..and you will get puffin of the battery if any longer, plates will separate ..
I should note trying to achieve max c can be dangerous is no different in some cases of shorting out the battery .. but keep in mind the battery booster packs for cars that cost 200-500 dollars have a smaller lipo and still get 500 or more amps out of them, the only difference is they have mosfets that limit the battery to only couple of seconds of full amperage .
Grate video but how safe is it to charge it again?
hi i've never had a issue re charging them..but not say its not dangerous .I do charge them at about 700ma-1amp now.. I use to charge them at 5 amps / 1c for what ever the battery is meant for so a 2400ma battery i would charge at 2.4amps ect..
One video i found said the puffing is when 2 plates separate and that causes the puffing. However I have found other videos or pages that say its cause from the charging process and gas is a by product from heat . I'm really wondering if its more on how these battery's are just rushed and not sealed up extremely tight. As they just build ship and sell with no worry of lawsuits like phone battery's where it can totally hurt a company with defectively wrapped battery's as they have to be really squished up tight in the silver package...
anyways if you can order a new one and chuck it or gamble like I do but thats on you.
Good luck which ever way you go.. stay safe and happy Rc ing..
Thanks for that video now I can fix my lipos,and save some money instead of getting a crap load of new ones.
Hei, is this a good idea to punture a lipo battery ?? I don't think so.
is it a good idea to make a homemade sky lantern that can fly off into a forest and catch 1000's of homes on fire?? I don't think so. =P .. but yes you are right its not the best idea to puncture a lipo battery . but for me it works. And if you can get replacement battery's in your country easily I would not suggest this at all..
Removing gases from a battery by punturing it can make the battery just looks good as new for your satisfaction but later on after a few uses it's power will gradually decrease means it drains so fast and finally one day it will be completely dead, i am saying this as per my experience because something like this happend with me. One of my 3s lipo battery was puntured during crash and i reapired this way but after some day that complety dead.
BDW, where i was flying sky lanterns there are no homes and dry forest and that time the season was monsoon, i am always aware about those things..... so don't imagine be practical.
@@niharranjanmahali8549 its been 11 months and all my battery's are still good.. However i no longer charge them at 1c or 2c . that's what actually creates the extra oxygen in the battery's . This is not the same as your crash example as this is releasing the oxygen nothing more. Unless you puncture through some plates and short them. My example of the lanterns, just because you do it safe does not mean one of your viewers will and they may burn down a village . However I didn't go to your channel and post that !.. I just found it ironic your first comment to me thats all.. . Your second comment at least you explained your thoughts on it , Even though your example is nothing about the extra oxygen and your just guessing what would happen to them . I did it and i know it works for a fact with nothing negative on the battery as all i did was released the oxygen on all my bloated battery's, If it didn't work , my channel is not about lying to people, all my mod video's are done in real time and if it does not work out I would post it didn't work . Or make a update video on it.
Also i would rather release the oxygen in the battery in a control fashion then having it crash and puncture and release it all at once around electric circuits that are most likely shorted from the crash. This is not about looks or making them look pretty for my satisfaction at all its about getting rid of the extra gas. But again the best thing to do is throw it away and get the bloated battery out of your house .
I don't care about people posting this and that about it being dangerous but I live in facts And i know for a fact that this worked because i actually did it on over 20 battery's of all sizes, with no loss of energy that just not make any sense that would happen.
oh btw I was looking into making lanterns about 2 moths ago I forgot all about them so I will be checking out your vids specially if you have a step by step on how to make them.. but i really do live in a country that has no outside fires during the summer months but would be nice to make in the winter..
Relax man, you wrote a passge?? 😆 I gone crazy when i saw this bunch of text. I am not saying you wrong and i respect your channel, what i said that was just my personal experience so forget those things, your videos may be is helpful to me and others.
Anyway, after all if you forgot our previous conversation then now as a good friend honestly i want to ask you one question, so the question is i have a 3s lipo battery (not much used) which was started popping last year and now that is popped too much on both sides but it's working fine and all cell's internal resistance is also good(between 5- 7 m.ohm) so sometimes i feel afraid that this is gonna explode if get popped little more, so what you think about it, let me know.
Instead of using a knife to scrape ect.. use a sharp piece of plastic!!! not sure why i didn't think of that until the video was uploaded..
Might be in a hurry sir but thats a great one
@@vijayakumarkona443 thanks...
You highly can damage cell cover with this knife method you did on video sir. Small needle can work better. I prefer cut the cell out and put there a healhty one. Anyways thanks for video.
@@jamesjay1987 yes like my above comment I should of used plastic or a piece of glass .. my first idea was to use the small needle you can see that on my board lol.. ..but was too nervous going through two layers.
given the capacity of it, i was literally sweating looking you cutting that plastic with a cutter
good stuff...
thanks
Good video, but i will admit it was hard to watch you use such a dull blade lol otherwise thanks for the video.
ty for taking time to leave a comment..
Dude, you seem like a really solid man but that's plain dangerous.
You could convert that from a 3S to a 2S of lower voltage but don't stab em.
Hi thanks for your comment and concern , Yes it would be simple but also dangerous in the wrong hands making it into a 2s battery.. I urge all to get a new battery if possible .The video is basically just showing that I finally got sick of everybody saying to throw them away because they are bad. In Rc and quad copters its usually just due to charging them or discharging them too fast. and none of the cells are actually bad. I have both battery's that were shown in the video and they both still work.
I'm comfortable doing this Now..
I've seen lots of video's of others showing how to take a 3s battery completely apart as well.
ElectrocBOOM made a video with probably close to 2 million views how to melt stuff with a microwave transformer. Now that is my limit and I would not feel comfortable showing or using something like that. Each to our own on our comfort levels.. But I'm also not going to post on his video to just buy some Bolt cutters..
.. but with all that you were not rude at all , you were pointing out the risks and a easier solution to something that can be dangerous.. .. So really thanks for the comment..
Dude, What were the police responding to in the background I could hear them almost through the hole video, what type of plastic scraper would you use? If I ever attempt this I’m gonna wear flame retardant gloves and safety glasses. I had one go up in flames once while unsoldering the puffed up lipo. Keep up the great video work.
maybe smashing a old dvd / cd case ..those come up pretty pointy at times.With plastic you have to wiggle it back and forth instead of scrapping and pulling up words..... That must of been scary having it go off right in front of u......Yeah if you do to it, Make sure its outside away from buildings, be safe..
I live about 10 mins away from our city's main hospital so it might of been that.
I find the helicopter more annoying now as that noise can make it into my house even with the windows closed..
@@ModItBetter thanks, it was scary, but it was mostly a smoke show. I used my water bottle to distinguish the smoke. No when I do any work to a lipo like changing out corroded balance leads or swapping out an old plug, I keep a cup or two of water next me just in case, I usually do it outside unless it's too cold, outside. Do you think silicone sealant will work for sealing up the lipo? Along with electrical tape? I have aquarium safe silicone.
@@calebsrccrawlers it might be safe.. but i don't know if the chemicals would interfere with each other if it got inside.. sooooooo maybe cut a really small square of electrical tape place it over hole.. then put the silicone over the tape and the sides of it then tape over that...not sure if silicone would stick though to either material as well..
I just looked on amazon and the metal foil tape(hvac) i used in the video you can get a role as cheap as 7 dollars Canadian..But really I only used that because its so sticky can handle heat and ages well...Maye the ones for 7 bucks on amazon are not sticky at all.. .. .. .Probably any kind of good 3m tape.... ..But if you try the silicon let me know how it goes and how it sticks.. All i know is electrical tape on its own is worthless as it ages..
@@ModItBetter I like your idea of electrical tape then silicone sealant. And yeah electrical tape as it ages doesn't hold up that well.
That first round was agonizingly sketchy.
As for cell separation..I used a credit card by slowly pushing it and rocking it back and forth between the cells. Worked really well you just have to be steady firm and slow ....with patience
thanks for sharing your method......yeah i probably should delete the first part lol..
Actually bro I will throw my lipo out and never do such things even if it will cost me a 1000$ loosing an eye or a finger worth billions to me, god bless you and be safe while working with explosives
Oh no doubt and god bless you as well. .If you don't feel comfortable doing something no doubt don't do it.. millions of videos on youtube about chemicals ..like nilered for instance they all play with Concentrated Nitric Acid .. and i would never do it.. .. this video was more a proof in theory.. Honestly its not that scary at all to me anymore but I would still strongly suggest buying new over doing this if you can. ..Regardless thanks for your feedback..
btw some nice glider vids..
@@ModItBetter thank you friend
not sure what that gaz is, but surely nasty
letting the gas out doesnt 'fix' the battery. The gas is just a symptom of the cell failing, letting the gas out doesnt fix the underlying problem.
agreed it does not "fix" a bad cell or make you pancakes in the morning.. but it does release the gas out so you can fit it back in tight spaces.. The only true fix for a bad cell is getting a new cell. Also changing the amps you charge the cells and discharge is usually Key buttttt the people that design our products go for the smallest battery's for weight and the fastest discharge to keep our quads ect in the air.
Dish soap and a credit card or fishing string is best to separate the cells.
thanks for the share..will try that next time i have to separate some cells..
Thanks
hey im trying to repair my mouse i took the battery out and i think it is punctured, im not sure if the smell is the glue or the battery is it like a sweet smell/chemical or something ells?
.edit... Most likely it is the battery, it smells fruity .. It is possible it is the glue but doubtful.. You might of punctured it while trying to pry the mouse case off with a screwdriver ect..??.. To be safe i would get the battery out of your house... Take note of the cell numbers 3.7v ect.. .. Also if the battery has a plug on the end you might want to cut one lead at a time to save that end so you can just replace the battery with another cell . If it does not have a connector at the end but is soldered in place.. cut one lead at a time close to the battery so you can twist on the leads from the new battery .
Or if you can solder just desolder it..
If you post a link to what the battery looks like . I can probably help you find a replacement if your un sure about that.
(Leave another comment saying you posted a link though as a rarely check my flag comments with links)
the battery might of been puffed up already and all you did was released the gas from it by accident. However because you did not do it in a control way ,you wont know if you bent some plates and can potentially short out at anytime. So its a pretty big gamble to keep using it.
Or I'm wrong and it is the glue.
@@ModItBetter thanks. Yeah it's smells like the green Palmolive dish soap lol
I took care of it and I should be able to order a new battery
What about using a tooth pick or sharp plastic object to eliminate shorting ?
yeah i added that too my description after the video.. should of used either or..
I have a 24s that uses a bms... I've clearly got some puffy cells and my bms cuts them off the rest of my battery... but I wonder if the puffy cells will damage the surrounding cells and spread the damage if I dont remove the puffy cell??? Any suggestions?
it really depends on your setup if its in a tight container it can squish other cells but doubtful it would do damage. I would be more concerned of the cells releasing all the gas at once / bursting (which to this day i've never seen it actually happen) Personally i would either remove them or release the gas in a control setting . If your management system is ignoring the cells that are bad.. is a good thing but might be a bad thing long term as well .??
..
If you do release the gas you might have to wake the battery back up with a very small current for 20 or so hours on another lithium charger( 100ma or bellow) ..Your bms might of let them get way bellow the safe spot for the battery ..
Personally if your bms is saying its bad, get rid of it ..as they can't detect bloated battery's and all the ones I have come across charge fine during and after I release the gas.
If your getting lots of bloated battery's I would look at the charging rate or the discharge rate of why its happening .. unless you know and this is just the cost of your setup.
@@ModItBetter thanks... I'm performing surgery on my pack as we speak as we speak... I'll have to decide if I should remove the damaged cells and run less in series but then I'll need to replace my bms too I believe for the correct number of series, or replace the damaged cells with identical cells... or I'm considering trying to release the gas out of the damaged cells and then rebuild the pack... we will see how it goes, I've got the heat shrink all off... why is this fun idk but it is lol although it would be more fun if it wasn't a $400 battery
@@MotoAlias well hopefully it works out .. if you are going to release the gas.. just really think of all the worst outcomes specially if its attached some how to many other battery's.. As allways do it away from any buildings wear the proper safety equipment take your time .. really pulling the cell that is glued to another one to me is just as much or more dangerous ..because you can actually bend the cell past its limit . Be safe and good luck with which ever way you decide to go..
@@ModItBetter thankyou... it separated very easily actually so I've got my cells to the side and I may try and release the gas safely tomorrow.
@@ModItBetter hey friend if my swollen cells are showing zero volts then is releasing the gas kind of pointless. Or if I release the gas I've gotta then wake them up somehow??? I'm on the hint for replacement cells but they're not easy to find
I don't see how that cell has been fixed, what I would say is the cell has had the puffiness removed, but the internal problem with the cell still remains, which could make the cell less stable.
hmm its like u read the title of the video lol.. its not fixing cell of swelled lipo battery..
also because its swelled does not mean you have cell damage.if you had cell damage it would catch on fire
@@ModItBetter It could yes but it's not inevitable, I believe that only happens when the cell shorts out either due to the dendrites or perhaps impact maybe even over charging.
But you were wise to be careful doing what you did.
Hi...my battery also slightly swelling after i bought it about 2 months...is it because i overcharged it?
it can be from a bad charger .. charging at too many amps.. could be what ever you used it for, drains it too fast.. And extremely possible its just defective.. If you have a balance charger that can view the charging of each cell be helpful .. one cell might at its max and the rest are still low . if its a multi cell (2cell ,3cell,4cell) ect.. If its a one cell those guys love to puff up from to much amps during charging ..
The #1 most common cause is letting them sit around fully charged for long periods of time. That will ruin a lipo quickly. Get a charger that has a storage charge setting. Always storage charge the lipo when you are done for the day. They will last much longer. A fully charged lipo will be 4.2v per cell. Storage charge is 3.8v per cell.
If you have a puffy cell, hook it up to a light bulb or spare motor or other small load, and run it *completely* dead, then dispose of it. A puffy cell is a ruined cell.
Awwwww man he didn’t give us an update. But if you see this, did they hold up?
Hi .. I just pulled them out,, I have not used them for about 8 months.. .. The first pack from the video are 3.82 * 3.83 * 3.85 so a tad off but not bad..
the second battery was puffy again just Now..9/7/2021 buttttt That means using the electrical tape and the metal tape actually worked.. I just simply peeled the tapes back and released the gas again. .. This one i would have to discharge i think before charging again.. its sitting at 4.2 * 3.8 * 3.87 ..If i remember right I got that one from banggood and one cell was always off from the start.. and the cell would over charge from 4.2 but that was 2-3 years ago.. its actually sitting at 12.6 so maybe later today or tomorrow i will discharge again and see how many amps it can hold again. Does not seem right to be at 12.6 volts after 8 or so months..(also if you add up the cells it does not = 12.6 anyways ..)
i was using the second to fly my quad again its been awhile because of restrictions .. the First one i had screwed up in the video I use with a dc to ac converter for when the power goes out to power my network Modem.routers for..phone /voip ect..
Anyways I took them both off the charger and will try to discharge them in the next couple of days and give them a full charge again to see what state they are really in.
Thanks man. Rlly helped me out. My 5 inch drones batts were getting chubby so I had to do this. The gas smells like fruit lol. Anyways thanks!
NOOOO IT WILL CAUSE A LIPO FIRE LATER ON
If the hole is sealed up really tight i'm not sure how it would.. its been 4 months now and I did about 12 diff style battery's.. .. So explain why it would later on! condensation if the tape failed?.. The hole is about the size of a pin head. so maybe seal it with something else beside 2 different style tapes? Like maybe really small piece of tape then epoxy over the tape?? I'm not trying to argue but instead of saying something won't work ,Explain why so maybe we can over come what your issue would be.
@@ModItBetter
It’s gonna fail one way or another never bother explaining
Some’s answers are based on fear mongering knowledge given from the news and other media outlets.
Just can’t win em all
@@ModItBetter what would happen if the hole is not shut? Would it degrade or would it catch on fire?why wouldn't manufacturers design these with somewhat of a valve to expell gases.?
@@rousdiandraos4397 I believe Lithium can possibly catch on fire if too much moisture is able to find its way inside . A release valve would be ok with a warning to only vent out side ect.. however if it was a release valve that automatically releases it all at a certain pressure it could be extremely dangerous if it was around something flammable .
@@ModItBetter the release valve is exactly the satchel. That's why it's in negative pressure to give the space when it react to the high discharge its inflates to release the pressure without escape the hydrogen and avoiding risk of fire.
cell is bad already once they puff i dont get why risk it ..my friend had puff packs and poke a hole and kept using it and it caught fire on the charger almost burn his house down...why risk it for couple packs 100 bucks or so just buy new ones aint worth burning down your home or hurting yourself
Hi thanks for your comment you are correct its easier and way way safer to get a new one.. If your battery is swelling extremely fast not over a year type thing.. then I would look at the charging system or how your using the battery you/he might of been drawing just too many amps or charging it too fast when he needed to put another one in for his purpose .. Personally it sounds in his case to be a charging system fault as it should of caught the problem instead of continuing to feed it more ,My guess his charger over charged it.
that was hilarious
U should soldered out first !its extremely dangerous to pilled it out like that😳
yup agreed .
Gas comming out i believe its O2
omg dude! stop swinging that box cutter like it were a machete! You could have damaged any of the cells at any moment! Also WTF electrical tape! USE KAPTON!
Kapton tape to wrap the battery when done?.. the only tape that concerned me was the tape that sealed the hole.. the electrical tape is just for a tight wrap..
Kapton tape for a wrap? Every time i get any sort of heat resistance tape its not sticky or stretchy .. Regardless thanks for suggestion , however if you make a video wrapping the battery with Kapton tape .. I'll be sure to post WTF why not use the larger heat shrink tubes to wrap the battery properly =P ..oops I'll also make sure to do it in caps ..
ah maybe your talking about 23:39 ..i just used electrical tape to shield it from the better metal tape.. yeah Kapton tape or a piece of plastic or anything would of done the same thing ..
i do have tons of heat resistance tape .. Curious why do you think that would be better to seal the hole then electrical tape?
Anddddd your right about the knife in my description I added, I should of used a sharp piece of plastic instead of something metal.. So 100 percent agree with you on that one..
@@ModItBetter
Use kapton to seal the hole. (also next time use a pin, the smalled the hole the easier it is to seal it air tight).
You could also use it to bind the cells together but think notmal scotch tape is more than good enough.
Electrical tape rots, it wont hold the seal for too long, 1 or 2 years at most, thats why use kapton which is heat resistant and the glue wont rot or dry after the years. The only downside with kapton is that its really sensitive to grease, so the smallest amount of grease on the surface or your hands will stop it from sticking, so clean everything with alcohol first, wash your hands, then make a tiny hole without touching the surface around it (use globes or a clean plastic sheet to push the gasses out) and then apply the kapton tape and make sure to push it tight. (use the edge of a credit card or some plastic piece and scrape the surface of the tape until you see all the surface take a darker color, that means theres no air bubbles and the glue is making full contact with the surface of the battery)
Kapton does stick but like i said its really finicky about grease. Also it does strick but very little. I use it to tighten the glass fiber isolation around the heater in my printers and even at 250ºC it doesnt come apart, so its all about knowing how to use it.
A trick with kapton is to cut the piece longer than what you need so that you have room to grab it, stick the clean section, and then cut the ends with scissors or a surgical knife (they are really handy) which wouldnt stick because you touched it with your hands.
@@laharl2k Thanks for the detailed explanation on how to use kapton tape.. I'll use it on the next battery .. keep in mind i still seal it with way better tape over it.. but the tips you gave will be handy , I really only use it for re flow or removal to protect other components .
the gas smells like mangos not lying i did this
Do you need to like add volts on the battery after that or thats the whole process?
thats the entire process.. just charge as normal. Well my normal was at 1c or 2c .. but now I charge them at around 700ma

What the actual Fuck
You cannot fix A battery one’s it is swollen ! You have to buy a new one if you try to fix it Lipo batteries are very dangerous you’ll be better off recycling it even though rumors that you can fix a swollen battery You can’t !
I appreciate your concern for safety when it comes to dealing with swollen batteries. However, I respectfully disagree with your opinion that it's impossible to fix a swollen battery. There are actually some safe and effective ways to attempt to fix them, depending on the type of battery and the extent of the swelling. That being said, it's always important to take proper precautions and consult with a professional before attempting any DIY solutions. In some cases, it may indeed be safer and more practical to simply recycle the battery and invest in a new one. Ultimately, the decision depends on individual circumstances and preferences.
lmao you didn't fix a damn thing. it's dangerous to keep using that battery
1 year later still using them. ok then!! do you feel better getting that out of your system.. lol
