- Firecrackers from 18650 that have been short circuit!!
We take a quick look in this video and try to get a thermal runaway from 18650 by shorting them out!
Did we make it?
No, Im afraid not. Take a look and you will see what will happen. Still.. If all your cell reaches 100+ like one of mine did..

I also love the music

The problem with this is. The medium that's shorting out the battery needs to be able to withstand the buildup of heat in the battery. If you're using the stranded wire. You need to make sure that it continuously keeps a good connection. If you're using nickel strip you got to make sure the way you attached it and then they will strip itself can handle the heat. But the easiest way to short out a . It is too short out the positive contact with the case of the battery. The shorter length of whatever you're using would provide least resistance and let the battery get hotter
I would rather this exploded in my pocket then have to listen to this music again.
arbit3r I'm really baked and sort of incidenily enjoyed the music... Till it became hard style instead of house as I wrote this comment
@@drewgalbraith4499 I am baked and absolutely hate this garbage
Idk man, you should see my leg
Yip yip hardstyle is the best yippppa
😂
a samsung 18650 just caught fire in my pocket yesterday , the positive end had peeled off and it shorted it's self in my pocket, touching something metal I had in my pocket , caused thermal runaway I could smell burning quickly took it out threw on floor and it spewed out lots of flames and smoke , as long as the cover is not revealed then this prob wont happen, but as they get older then this will happen to a lot of them , so need to dispose once the cover wears away or maybe put more proection on them ie shrink wrap or something to stop the shorting accident
Thanks so much for taking the time to do this. Very interesting and I expected worse to happen
Thank you for your video! I’d like to build a simple styrofoam cutter with a 18650 short circuited. Do you suggest to add a resistor or a diode to prevent damages to the cell or is it simple as that?
If you want to connect a heater to the accumulator, select the resistance of the wire wisely, so the load won't be more than the cell can output safely
thanks for making this! i always wondered what would happen if i shorted one of these out. now that i know what happens i dont have to do it intentionally :D
WOW!!! this is so great, very informative! How do you know what the chemistry is inside? EDIT: Oh, I see the chart at the end isn't the batteries you tested. I got confused.
Beakerzor no the chart is over several chems. i just compared to the worst one. :) but note as i said... they were alone. what would happen if this happens to all of them in same pack i dunno :)
Very good test thank you
i guess i short curcuited my li-ion keeppower with a metal caliper - is done ?
you gain 1 new subcriber here
i've looking for videos like this, testing batteries and make it shortcircuit so we people could know what to avoid
2:14 the moment my ears left my body
Thanks for that! I was in a robotics lab for this internship a few years ago, and my buddy went to cut a wire off of this large battery we were using, and when he snipped it he touched both terminals on accident with the scissors, and the battery immediately swelled up to twice its normal size! That battery was much larger than these vape batteries but every time I hit my vape I think about that ha so this video makes me feel better.
Wasn't it a Li Po battery instead of Li ion?
It was totally a LiPo accu
I use this type of batt in my ecig, and I have a question. I have made a mistake let the positive connected to the negative for 1-2 seconds accidentally, and the temp of the batt was increasing suddenly. Then I took the batt out of the device (mechanical mod). My question is, can I still use that batt as usual again?
Thank you
Ekasit Wong Most likely yes.
DIY Tech & Repairs thank you, that’s help 🙂
May be able to use it but it wouldn't hold a charge well one would think
Please dont use a mechanical mod unless you really know what you are doing. People have horribly died by accidents with these devices. With a malfunction of the device, The battery could explode and launch the mouthpiece with a lot of force into your face, litterly INTO your face. Please be carefull.
Why didnt they rupture? Is it due to the protective casing? Is this by design or by chance?
Could you tell if they were venting? It looks like they were in the thermal image.
No i could not tell if they did vent. I only think the CID pulled by the high pressure. The cell had no contact after but pressing the cid in the started to work so i guess they didnt vent. The protection did what it was suppose to do. Remove the external short :)
Yea, but if they are in your pocket it is covered by denim insulation the temp may go higher to 200C. . Most of the power walls you get have them connected in parallel, so if one goes short, all the power from the other batteries will rush to it. In a Tesla I think they put batteries in some type of fluid so it always stay cool. Still nice video.
More tests to come! And no im not going to test this in my pocket :D
If it can reach 100c in your pocket without you noticing...
tesla puts battery in fluid? er... no they don't. no one does that wtf
@@riskinhos yes they do. The cells have liquid. It’s not physically in the same container as the liquid but I believe it’s aluminum used to transfer the heat.
@@ericklein5097 no. they don't. cells have zero liquid. at all. don't be retarded. if it's not in the same container it's not in the cell you stupid moron
What was the ambient temperature?
Dont remember now but between 15-20c i would guess
Nice work mate, thank you!
I guess I am safe with testing the max current output by shorting the accumulators with the multimeter for a second
Nice video testing that makes me feel much better.
Thank you
The surrounding temperature is 5° and they are freely cooled in the air. Remake that with 30° and some other stuff packed around it.
1:09. Your DMM just vanished into thin air, as if it were saying "If this guy is going to explode batteries, than I'll just get outta here!!!"
That's more than high enough temperature short circuiting in a pocket or purse with keys and coins.
Will it charge in the same time?
you want to see an explosion you make a perforation on the negative part of the body with a screwdriver
Great video as usual!!! now go back to built more packs. :)
You just got a new patreon member, if you need batteries I can provide you some (but not new), cells are not an issue because I have so far thousands of them but let see how much the parcel will cost from Spain. As I said in previous videos you are doing a great job. Let me suggest something, after seeing one battery can't get burn by itself next experiment would be: how many cells need to tackle one cell in order to get in to flames. This will help in order to know how many cells can be arrange " in a secure way. many thanks again for you job
Thanks m8. Yes i should test that. 2nd hand batteries i have 100s of that im willing to spend just for pure simple testing. The question is how many batteries i should short out in a pack? Should they be tightly together or just in that plastic holder type :) There is 1 thread on the forum diypowerwalls.com about how to put it out. Should add another thread about this above topic to. The more suggestions on how to do the test the better the test will become.
DIY Tech & Repairs well in your current test you just put all the amps of a single and wasn't enougth, but if they are part of a pack and you get a short out the sum of the rest of the cells will go though it. Final question would be: how many amps we need to put in one cell to catch fire and how many cells we need to put to generate a fire. Rohan (the firefighter) by mistake did it but we don't know how many are the limit.
Yeah its a big question. What if a cell shorts and rest of cells send their current into them...
Then fuses on the 18650 would most likely have caused them not to short. So that is something i would like to test for sure.
I have tried several times to put in like 10A and 10V straight into it. 10 out of 10 cells the CID popped instead... But this short/discharge test the CID did not pop :)
So question is also if discharge vs charge vs short/shart differs when it comes to what will happen to a cell.
Next test for now is to short 4 or 9 cells that are tightly together in a pack and se if that will get them all to heat up enough for thermal runaway...
Not sure how to test if 1 cell shorts and then current rushes from the rest of the bats. I have no way to make an internal short hmm.
DIY Tech & Repairs, great, perhaps the easiest way would be putting it oposite and it would be like a short cut. cheers
6 or 9 cells in short. Need to be fast and solder a big wire on it :D Thats is quite some current going through....
Seems like only the LiPo batteries are going *boom*
It was interesting to see, thank you. I've witnessed much more.. Let's call it explosive results myself while assembling a battery, I only short circuited one cell - but the nickel plate it was done with just instantly exploded.
The battery was fully charged and rated for 30amps though. These guys clearly have higher inner resistance.
Have you ever done it to any fresh high performance cells? (those usually used for vaping for example)
in my case i accidentaly put wrong - and + in wrong position when charging form panel. I was expecting nothing bad to happen withing few second short circuit, but one types of noname batteries in my pack had electrolyte leak
Any of you watch Alone? That would be one hell of a cheat. Just take some trapping wire and short the battery somehow.
Another exciting video! One thing you could do is peel back the sheath a bit up by the anode and short directly from the cathode part of the battery case 3mm to the anode with a chunk of copper or steel and a magnet. It wont make a ton of difference but you will eliminate the 10-30 milliohms that are your 12 ga or so wire you are using. Remember as a conductor heats up its resistance goes up too.
Keep it up...still waiting for your first crazy video to go viral ;)
Why do everybody feel music is required? If I wanted music I would turn on the stereo.
bs ! i SINGLE drop of water on internal flashlamp charge port
. with hiss and smoke result. it stopped power button turned off. i remove the batt and sent to recycle trash.
Shorts and heats up.
BILTEMA FTW
3:56 Nice _shart!_ Lol
Lethal around 150 degrees, but he didn't come close to that one 🤣🤣
2:35 Damn you got me 😂
Thanks for an informative video. One thing I was thought was strange was that the cells with higher internal resistance (200mOhm) got hotter than the others (130 mOhm). The power while short-circuiting should be higher for the lower resistance, giving a faster heat up. Moreover, they have higher energy capacity so they should be able to go on and heat longer. Or is it something I'm missing?
Its the resistance that creates the heat :) The voltage drop over that part induces the heat ;)
Yes I know, but the power dissipated in that resistance R is P=UI = U^2/R. A smaller resistance would increase the power (given a constant voltage U). I wonder if there are any kind of PPTC fuse limiting current on overheat integrated in the high capacity cells.
Background music is Euphoria type?
ear assault
Hand warmers?
Yeahhh do it with a mxco 18650 "IMR" 30A fully charged battery... IMR are the exploding ones.
it would have exploded if any type of spark were present. even static electricity that you would normally never notices ,will ignite that venting gas.then the chain reaction begins.
What were you thinking, putting that awful noise in the background?!
Steven Bracken that i will get a comment from you :)
Good video. Next time lose the music.
Sure. Will use the same music for next video.
can shorted 18650 still be use?
No. They should be recycled
There is no other way but to test this in vacuum. Vacuum will provide perfect isolation. Those cells will go kabooooom in no time.
NefFy
I still wonder about the little insulator ring on the end I don’t know I’m being cheap and also think they are just overcharging for something that you could probably get for free or don’t even need like what if he just pulled the tube a little further and shrink wrapped around the battery so that it went where the circle was… I’ve heard of some people using pieces of cardboard from business cards and some people are using electrical tape… Personally I’ve been using shit batteries that are probably due to explode because the rappers were torn to shreds.... The real reason why I decided to look into this was because it zapped me when I was holding the battery in my hand not even holding the mod
I don’t know what is the part that is safe to touch and what made it shock me but it kind of hurt and it’s happened twice lol fuckers
Meanwhile I decided to put on some rubber dish gloves just to be safe even though I don’t even know if that would keep me safe ha ha and I wrapped up my batteries real tight with one layer of electrical tape. This would’ve not worked in my single battery date because it would’ve been too fat but maybe now is a need to drag and it has two slots for the batteries and if it’s just fine. I pulled the tape tight enough that when I got to the top it curled over and cover rent a little O-ring would go....
I read so many articles online trying to figure out what material things were made out of NY to see if I could make an O ring at the top that was just as good as the ones they sell and if I needed to buy the shrink wrap stuff or if I could use some thing else as well. I mean the electrical tape is working but so was the ripped up battery that was electrocuting me so I’m trying to figure out the best thing to not get shocked and not have a blow up in my face without buying premade shrink wrapped in a little cardboard Os.
This is Melissa this is mostly out of principle and being cheap is the other part of it. I like making things and I don’t like getting ripped off and I feel like what they have on the market isn’t really necessary but they make it seem like it is. I could be wrong I don’t know but I thought this would be a video if you feel like doing even more research than I did and figuring out how to DIY these things. Maybe you don’t even care because you say the wraps are dirt cheap (but even dirt should be free) and they work and it’s pretty easy so it isn’t worth doing anything about it.
Anyway anyone is curious the rappers are just made out of PVC there are tons of things made out of PVC but you have to get it in a tube not just put out a piece of PVC from a plastic bag because then how is it going to stay on your battery?
We can buy much cheaper versions of the same exact thing they sell as “Vape battery wraps” because it’s also sold as something way less specific and the exact same thing just not “for vape batteries” is available at pretty much any hardware store ( so there’s no shipping and you can probably get it the same day if you get out of the house and go get it)
As for the O-rings at the top they are made out of something called Fish Paper.
Some are made out of plastic. Some say they aren’t even necessary. Some people use lucky duck tape or electrical tape. Some people also don’t know what you’re talking about so there’s that too. Plastic seems to make sense to me or actually better than that would be silicone that way in case anything gets hot it won’t melt or do anything weird. At the top of my lotion bottle sometimes there is a little thin circle of silicone and I was thinking of getting a whole bunch and making a whole bunch of the middle and then sticking out on top of my battery… I’m pretty sure I also have some thing in with all the miscellaneous Vape supplies I have looking a lot like the right size and shape and made out of silicone along the lines of a Rings and stuff.
So yeah I kind of gave up because it was taking too long to re-search but that’s as far as I got with everything and I don’t know if anybody even cares or is curious the way I am but there’s my research and an idea for a video.
I've mainly been curious about the wrap but as an electrician I know it's just a thin layer of insulation to prevent anything conductive from contacting the metal casing of the battery, if you consider the fact that we used to use a thin layer of cloth to insulate wiring in buildings (most of which haven't burned down *yet*) using electric tape instead of the fancy battery wraps will definitely suffice as a proper insulating material as long as it's done properly (tight with overlaps and a couple of wraps leaving no metal surface exposed using quality tape not dollar general kinda crap, 3m type line)
Your answer was educational though.
are these protected or unprotected cells?
Unprotected standard cells. The most Common Ones. Unprotected as in No electronics but only CID
I've got some 30 amp cells you should try that with.
Are these high amp batteries?
Noop
@@DIYTechRepairs ok. I'm pretty sure high amp would explode.
@@doknox not really. High current cell also have cid implemented.
@@DIYTechRepairs try a battery for vaping. They explode.
@@doknox No they dont. IF they för they are faulty from start. A proper cell have cid and the cid trigger before it goes bad.
So we're all in agreement the music sucks
Lower internal resistance -> less heat. Having valves -> no explosion due to high pressure inside the battery.
You said nothing happened but it kinda looked as tho it was venting on your thermal cam
It was warm air that you can see. Especially the non covered areas emmit alot of heat causing the air to look like that on the flir :)
@@DIYTechRepairs I would think it wouldve been orange colored on the flir images
I think it is important to say that this video should NOT be considered reassuring!
- We do not know the characteristics of the cells nor of course their history. But
- These cells probably come from laptop battery packs, which are not designed to deliver high amperage.
- The ambient temperature is 5°C or less, the result could be different by adding 30°C.
In conclusion, it's not just because nothing happened in THIS video, with THESE cells and under THESE conditions, that mean that nothing will ever happen in other circumstances!
Also, short circuits are not the only thing that may cuase Li-Ion cells to fail, possibly dangerously.
If some of the guys playing with these cells have been victims of fires or have come very close to a possible disaster (see HBPowerwall at the beginning of the year), it is not just by bad luck. It is because they were not careful or informed enough, or too confident.
Correct. In normal scenario the cid takes Care of it but No guarantee. Its like that with everything in life. Just because you have a seatbelt driving a Care doesnt make it 100% Safe
Its safer but not more...
I imagine it would be a lot worse if the wire was really short and you connected it from the positive terminal to negative body, instead of end to end. Less distance for the current to travel, meaning it would heat up really fucking fast, and kaboom.
Thats my theory, not claiming to be correct though.
Pretty sure wire length wont make a difference unless there is massive resistance in the wire itself. Wires usually have no resistance, that's why resistors exist.
They didnt explode beacuse they have swich that triggers at certan temperature
They dont have ptc but a cid. A cid is triggered by internal pressure ;) thats why they didnt explode in this case.
@@DIYTechRepairs oh ok then thank you for response.
Its not protected cells? Sorry my english bad.
Hardstyle is sick
Short circuited but still no thermal runaway. Wow.
i blew up a lot of components back in my school days, never to this day i could burn a 9v battery. sadface
Yeah I think your tester incorrect because I just had a thermal run away in the backseat of my truck yesterday
Its noting happened, but if you tuch the battery with something like wood that battery will being a time bomb
Great 👍
this test dosnt rly show anything... u can put some batteries in ur pocket and coins etc and it can explode instant! u cant test 100 batteries and think the outcome is the same every time!
No they can not explode in an instant in the pocket. You are thinking about things you have heard about high end cellphone batteries. Those are of a different type and energy density. Nobody uses those cellphone batteries for home battery building.
This test shows very well, that if your setup has heat monitoring switch - you can easily avoid fire risk.
Wires should get hot
Being an 80's kid and a multiple time reader of this book I can tell by the trailer and teaser footage this is going to be a major let down and completely ruin the story.
They have protection circuits. What did you expect?
Mussie Tesfay they have cid. What did you expect since you watched the video? ;)
DIY Tech & Repairs what is cid.
CID is a pressure valve that will disconnect the positive end if pressure is built up. Or limit the current in some cases. Above cells tested do not have built in circuits as such. batterybro.com/blogs/18650-wholesale-battery-reviews/18306003-battery-safety-101-anatomy-ptc-vs-pcb-vs-cid
Throw a wet rag on top that always does the trick
Hi. It's three years old but maybe you are still interested in new batteries. I live in Sweden and can send you some Samsung 35E and 25R to test, would be interesting.
Let me know here if you are interested.
No boom. :/
Noop :/ The one that gone to 100+c i thought would do something but nothing. They just kind of vented but not more. Not even the cid did break on them so i was surprised...
100C boiling water, burn finger skin off
@@3D_Printing but no boom :/
@@luongmaihunggia no fizz :/ either LOL
No shit. Guys a liar. F him and his channel....made us waste our time
They dont explode just overheating
Well, a lot of myths spread on the internet are just that. The reality is far less intense.
Most varieties of Lipo battery packs do explode when short circuted.
Why did you say that the battery explodes in the description if it doesnt? Dislike from me
Never said my cells did that. It's more of a statement. Could have added a question mark but whats the fun in that?
@@DIYTechRepairs then what does the part where it says "shorted and go boom" mean lol...what's the fun In making your video title accurate? Gee idk I'll let you figure that one out
@@dustinlaverdure6711 As said its a statement. Il let you figure that out :P Apparantly it worked since you are here? :D
Your face does not match your voice ;-) You voice says India ...
:) I have been working with india people for years so perhaps thats why :P
The voice does not really say India imho. When the Biltema multimeter showed up, the Swedish accent was evident =)
You tell people to stay safe, but make this video and tell people "that nothing will happen". Surely you realize that 18650s come in MANY different rating. Your old laptop batteries are only cabably of a couple amps. What happens when your ignorant (about batteries) viewers use cells from power tool batteries, that can supply 30 amps or more? It is very irresponsible of you to make this video and claim that "nothing bad will happen" when your very small sample test means nothing on the grand scale of the plethora of different 18650s and scenarios. I think 18650s can be repurposed and used relatively safely if people fully understand what they are doing. You are feeding people false info and security and that is always dangerous in any situation. When lithium batteries go nuclear, it's very dangerous and "shorting" is the cause. To claim that it's safe to short lithium batteries is stupid. Sorry if I offended you, but I don't want anyone to burn their house down, or get hurt.
Did you even Read the topic? It have a ? Its Up to you as the viewer to determine whats safe here. Ignorant People exist everywhere and you were probalby One not reading the headline :)
@@DIYTechRepairs I know it is up to the viewer to be safe, but many people don't do that. Your headline doesn't mean shit when you claim that "nothing will happen", because many times bad thing DO happen when lithium batteries short. I explained that such batteries vary greatly and you made it seem like your test encompassed all 18650s, so I'm not the "ignorant" one here. I read and listened to everything you said in the video and that is precisely why I said you were being irresponsible. You also have a responsibility as a content maker, especially since you realize that many ignorant people will try what they see on a CZcams video, not knowing what they are doing. Why don't you short out some 30 amp Dewalt cells and see what happens, before you call others ignorant.
@@gordthor5351 The 30A dewalt cells do the same thing (If you read their datasheets or the test protocols for them). Yes i tested them to. I guess you are a bit to ignorant to know what i have done and you just assume things. Same as you did with the video.... I guess we are back to square 1 again. Plenty of things are unsafe in our life. Walking across the street is also unsafe blindfolded.... With this said lithium ion cells arent something you work with unless you have the understanding. We can protect people from alot of things but from their own stupidity is hard.
i had an 9v battery accidentally melted because of short
i didn't want to take a look at your shart
This music should be banned
Nevermind the batteries you Just destroyed the video with that crap music...
