#RCVideoReviews - Věda a technologie
Every single person in any part of the greater RC hobby needs to watch this video! Thanks for this video, guys! Well done!
I 100% agree. Thank you.
thanks for rcvr team for running this experiment, one which a good number of people have yet to have an experience with a lipo reaction and probably have no idea what a reaction looks like
I've seen a couple of lipo fires, but this taught me quite a bit.
Thank you for burning money and destroying your patio. Seriously, very much appreciated!
No worries!
I would love to see these on top of something flammable like carpet or wood to understand if these would be hot enough to burn material through the bag
must watch thing , thanks guys for all this effore , a like is not enough .. i give full it full credit
Much appreciated!
Double bagged and in 50cal ammo cans, that is how i roll for my FPV Batteries. Although i have never seen or heard of one blowing just sitting in storage.
Awesome test. 👍👍🇺🇸
Thanks boys. I treat them with respect. For sure! Thanks for the sacrifices!!
Im buying me a lipo bag for my filing cabinet.
This gives me much more confidence in my lipo bags. Thanks guys 👌
21:15 Smoke is intelligent form of life. Whenever you have barbecue, camp fire or lipo burn, it will find you. 🙂
You know it.😂
Great video. Your tutorials, especially open tx and Edge tx have helped me alot. Keep on with the good work 🙂
Thank you for this vlog!! This is one of the best !!
Great test and showing that these bags do help and increase the safety factor.
Big time!
This is a must watch!!!! Thank you so much.
You're welcome!
Great demonstration. Very important information. I have three of the box style lipo bag. I always store my lipos at storage voltage in those bags. And I don't charge unattended. 🤓
I use both of those bags. Excellent experiment. Thanks
Thanks for this video. I learned that even if one cell goes it does not mean all will go. Regards from New Zealand
I was very surprised at this outcome. Thanks for the comment.
Thank you for doing this!
Thank you for the video. I was very curious about the performance of these li-po containers.
You are welcome!
Getting a bag right now!!! I’ve got a few older batteries and I’m convinced these work!! Great video man.
I ordered a replacement for the bag I destroyed in the video.
@@RCVideoReviews good review and great realism of how the bags react. They seem strong!!
Very useful video.
Sharing this with my flying buddies.
Thanks!
Great demonstration!!
Thank you.
The bags performed better than I thought. Fire only happens when Oxygen is introduced by opening the bag. Good job guys, I leaned a lot. Thanks
The problem with lipo fires is the reaction supplies it's own oxygen. That's why you can't just smoother it. Like they said in the video, you need something to break the reaction..
Thanks this an excellent video, I wondered just how well the Lipo bags work, really good is the answer.
They surprised me--that's for sure.
I just received some bags and was wondering the same thing lol thanks for the test
Thank you. Great test. I've always assumed that the fire would become uncontrollable with multiple batteries. It's good to know the bags work.
You're welcome.
Just purchased one of these bags on Amazon and was wondering the same thing…do these bags perform as promised? Thank you so much for this important “community service experiment!” I feel much better about my purchase now👍🏼
I use bags inside a metal ammo box. That would've been a good addition as well as I've heard the ammo boxes are really good as well
Thanks, very helpful
You're welcome!
Very interesting, I have always kept my lipo's in these type of bags. Nice to know that they contain the burning flames 👍
i admire your courage to be there with so much bad smell. Thanks for the video it's good educational video
Thank you for the video. The price of burning all those batteries probably add up quick!
Those batteries did cost $$, but we burned batteries that had been taken out of flight service due to age/puffiness etc...
You're welcome for the video...
Thank you. I, like many others have that smaller Lipo pouch bag. Good to see it tested.
This gave me some Ideas based on what I saw here:
1) Keep a smoke alarm IN the bag, you'd hear it if your in another room...which let's face it us what most people do.
2) Store less batteries per Lipo bag, have multiple bags with only 1 or 2 batteries in there.
3) Make note of total cell in your bag. If you know there is a 6s and a 3s in there. Count the pops off ass the burn up. If you haven't counted to 9, wait.
4) Would a sacrificial non-pressurised container of non-flamable expanding foam in the bag help. Idea: it breaks out of it's container from the heat of a broken cells, then quickly fills the bag volume with foam, thus reducing oxygen volume in the bag = more time to act and get that bag outside away from valuables.
Thank you for your demonstration.
If you must put out or contain a lipo fire whether as a result of puncturing or overcharging, what is the best way (personal experience or published results) to do so? Pouring sand over? Submerging in water? Covering it with a bucket? Other?
Nice job guys. I usually store my batteries in an ammo case
I've just watched a video of a Lipo fire in an ammo case, you should probably get a Lipo bag unless you want your ammo tin spitting flames 2 foot in the air like a flame thrower
@@dannyherbert4482 🥴😵💫😮😧
very educational!
Glad you found it useful.
Wow, that must have been expensive !
Nice to know. Thanks.
Sure thing.
John friend’s commentary is priceless.
Thank you for making this. What I have done is put each battery in it's own single fireproof bag and then put those into a bigger zip bag like you have. I wonder how they would do. Also interested in what a charge fire (while it is over charging) looks like.
But this is super helpful!
I'm going to do a v2 video with some of the more common requests. Thanks for taking the time to leave a suggestion.
I put 3 in a bag and then 3 bags in an ammo box.
Thanks,interesting!!
You're welcome.
Thank you so much for taking the risks for our education. I only charge outside, apart from the little 1S for indoor whoop flying which are charged in my office in a tin.
You're welcome. Glad to help.
The bag is pretty impressive, it stops the chain reaction when the bag is closed and the oxygen is used up.
Yeah, it is impressive tech to contain that much energy.
I would be curious to see the difference between a 4.2V/cell and a storage voltage battery.
I think this video will save so much damage and very likely save lives. Cheers lads.
I ran a similar experiment with similar results. While not perfect, the lipo bags are a worthy investment that buy you time. Also thought of something else. How many of use bring a fire extinguisher when we fly? Another worthy investment. Shitty to lose a battery or plane but worse to light the surrounding area on fire.
Great video...🍻🔥
Thanks for doing this. Ive been really lucky so far but try to be safe.
You're welcome.
I Did learn something today. (Oh, wait... that's a different channel. 😁) I too expected a quicker chain reaction. Seeing an unburned pack right next to a burned one was a surprise.
Makes me add trying to think about reducing smoke damage. Have seen box that has smoke filter.
Probably a good idea because the fumes are dangerous and it stinks.
very nice..
I store batteries in ammo boxes..
I wonder how they would go.. one even has a breather hole..
Great vid
Thanks!
could you test with full discharged batteries. Is this safe when battery has no energy.
I am planning a v2 of this video. So keep an eye out on the channel.
good video on Batt safety, if your cheap, i see, you can still use the battery connectors Tx30 ect,.
That was a great video, I always wondered how those bags would react. I also keep my batteries in a ammo box, curious how that would react in this scenario. Thanks again for the video.
You should make sure the ammo box is vented somehow. You don't want to build a lipo bomb.
You're welcome.
@@js32257 yes, I always leave the top unlocked and cracked open a little…
@@Joneszee1969There is probably a gasket in the lid you can remove. It's to waterproof them for ammo, but will leave an air gap if you pull it.
I'm using about 4 of these to store batteries, but fortunately have never had them tested. I'd like to see the results, too!
I would also surround the batteries with sand-filled ziplock bags, to assist with extinguishing any fires.
I keep my lipos in a steel ammo can from the military surplus store. They're dirt cheap, and if they keep ammo safe im sure they can contain a few lipos
When I worked with batteries we had "Hot Battery Boxes" which were Peli cases full of graphite powder. When a battery was compromised we would put them in the graphite powder which would contain any fire and discharge the battery in a controlled manner. Then take them outside where they were left for a day or so before removing from the box. This was very effective but the mess the graphite powder made was not easy to clean up.
9:50 why .. at 3.8volt they won't burn? or hardly? 20:00 IF they would catch real fire, maybe they would burn all together quickly, but since it's only smoking?
Hello, how are you? They will burn at 3.8 V per cell. Just the fire will be smaller and shorter. Because there is less energy stored in the packs that it would be if they were fully charged at 4.2 volts per cell. No fire is a good fire, but definitely a smaller fire is better than a big one.😂 Plus good maintenance and handling of the batteries such as not overcharging ,over discharging, overtasking the batteries and maintain them at storage voltage and balance just makes for a healthier battery, not very likely to just burst in flames all by itself.
I always figured with these that it would give me time to toss the bag out of the house or car..They do work.
I use empty .50 cal. ammo-cans with installed overpressure release valves to store (and charge) my Li-Po packs. I either place these boxes on a concrete floor or on bricks, to prevent heat transfer to a combustible surface.
Man. I dont think that bag would work. But this test shows that it does. Thanks for the video!
Ditto. I thought a lipo fire would cut through these bags quick.
@@RCVideoReviews or is it because battery technology has improved? 🤔 Less fire, more smoke
The one thing I wanted to see ,was did the outside of the bag get hot enough to set fire to things on my desk? Paperwork , plastic items do the walls of the bag insulate as they are supposed to?
Brilliant video thanks
We're going to do a v2 video. Keep an eye on the channel.
The bag worked I would not have tried to damage the rest of them to see what survived, but hey, it leaves opportunity for more experiments 😂
Yeah, we're planning a v2 to try a few different scenarios.
Thank you for sacrificing batteries for our benefit! It looked like the larger bag’s zipper is what burned, not the bag.
Is that what you saw?
Thank you.
The teeth on the zipper survived. The zipper material separated from the bag. The fire probably burned the thread allowing the two materials part.
Watched a video on CZcams where he was overcharging a lipo battery and actually left it on the charger and just left it to run until it expanded enough to blow up and it did blow up
Yeah, I kinda want to do that just to see it for myself.
A test I'd like to see is if they stabilize inside the bag - i.e. leave it for 24 hours closed - does it ignite when you open it?
I know it’s a ton of money but invested in an 800wh lithium sleeve from a company named cell block.. they market products for companies like ups fire departments defense ect huge lithium batteries.. I also have one of the boxes.. again it all depends on how much want to spend is it worth it.
Interesting test, BUT, if that bag was set on top of carpeting, would the bag have gotten hot enough to melt and ignite the carpeting, thus burning down a house?
Since we didn't test it on carpet inside a house I have no way to answer that question based on observable fact.
If had to guess, I'd say no. The bag wasn't hot enough to initiate a fire on nearby combustible sources.
A lot of newer batteries use a different chemical make up in lipos that produce more smoke than fire and I have noticed that fully charged or used around 3.6v a cell they still will burn almost the same if they go up but yes a fully charged batt is less stable sitting around.
I like my old ammo cans to keep my lipos in. the "exploding" part, is 99% because the charger malfunctions, causing overcharge of the cells. When overcharged, they are explosive.
They are also explosive depending on who we’ll they are built. How tightly the pouch is sealed and how strong it is. I’ve seen tests where the cells to pop and make a bang. But most people who say “LiPo explosion” really are talking about round cells like are in e-bikes and computers. Those almost always make a loud pop. Just the nature of their design.
It's great if you can take the lithium pack out. But sometimes they are non removable.
Just FYI, my first battery for the Phantom, was dropped and hit a rock. It most definitely did pop open like an explosion...not super loud but exploded open into one very big fire!
Yikes!
😅 my audhd was yelling about the water not working and actually being dangerous. thanks for the extra explanation
:)
Some guy was trying to sell me a LG 7s lithium ion battery with swollen pouches claiming it’s safe to use. No way. No freaking way.
Good call.
Any ideas on where or how to dispose? My local shop doesn't dispose them anymore.
Watch this: czcams.com/video/_9Sw8RpYHwM/video.html
I literally just opened that exact lipo bag today... Guess i'm about to find out if I need to return it
I think you'll be happy with it.
Would like to see dual lipo bags. Those battery size ones inside a larger handbag.
Could have added a test putting a stack of newspaper on the bottom and let's see if the heat is also insulated or dampened enough that there is no secondary fires generated outside of the bag.
best F@&k around and find out video of the year 😂
Great information here I rely solely on these bags for storage of my lipos it’s reassuring to see that they held up to the test.
👍😀
I have ten small 1s batteries. I think this bag will cope with them if something happens
Hola 👋.
Cuándo vas a hacerle un vídeo al nuevo lanzamiento de Radiomaster, el dongle para actualizar receptores ELRS?
Saludos desde Cuba 🇨🇺
Should do video with ammo box that seems so be the standard lipo container I have 2 and a few bag for going to the field
Seems there's interest in the subject, so we may do a charge fire too.
You Should try Bat-safe.
😂 Looks like two OSHA instructors lighting a match... No, it's really a great video, thank you!
:)
👍😅
Glad you have extra money to demonstrate the danger we face..
A really good test, but I cried watching more $ worth of batteries than I own go up in smoke.
Experiments can cost $$ sometimes unfortunately. :(
Hi I'm new to fpv. I have a question. I have a charger that put the batteries into storage voltage. After they are in storage voltage and I unplug them from the charger how long will they stay in storage voltage before I have to do it again?
I don't have the patience in my life to run that test. In other words--for a very very long time.
Better a bit safer than sorry.
Right before christmas a club member had a lipo fire in his house.
Lipo fires don't happen often but they do happen 😢.
Do the best you can to keep your loved ones safe.
I had a battery burn my quad and the whole battery looked toast, it turned out one cell and I had the best 5 cell battery ever, after that. It's still good and strong.
I've seen people recommend a metal ammo box. I'd like to see somebody test that with the lid open a crack, vs with holes drilled, vs unmodified and sealed shut except for minimal holes for charging wires.
I saw a "test" from some company trying to sell their safe box showing the ammo cans would just explode, but they intentionally didn't modify the cans. The trick to keeping them safe is apparently to remove the rubber gasket allowing pressure to vent but not much airflow. I'll dig around and see if I can find the videos again but I think they might have been removed by now.
@@AchronTimeless Neat. That's what I've been told elsewhere about ammo boxes, but I've never seen it tested.
@@raztaz826 I tried pasting a link but the spam filter must've blocked it, youtube is notoriously bad about letting you link to things in comments. The video title is "How to store LiPo battery safely - In depth LiPo fire tests" and includes an ammo box left open, closed with no seal, closed with seal, and with a bag of sand on top of an open can as an attempt to auto-smother the fire.
@@AchronTimelessthanks!
John ..bad boy....sticking your hand in there like that , no protection on arms and face..even with safety glasses..hahahahaha..I almost jumped out of my chair !!!! you must have punctured more than 1 cell...maybe three !!! .....I think that's when molten material gets ejected all around !!!! great video..thanks .
Testing my reflexes...they still work.
That's actually scary given these LiPO batteries are everywhere these days...
Lot of energy in these little devils.
Hope your lungs are OK after being downwind of those poisonous gases.Good test,and reminder.
I'm still standing. Won't be the worst thing I've inhaled.
Good video but for a test like this - gloves wise get some stick welding gloves. Those mechanics gloves offer very little protection
From someone who has experienced a lithium runaway event with a 16 cell fridge pack having metal encased cylindrical cells, they have a much louder "boom" and actually explode and send fire balls all over the place. You have to run and duck for over!
The bag catching fire has to be a fail. While it certainly bought time in a supervised situation, like charging, storage, unattended, that would be a fail. But that brings up an interesting question. Is the bag only needed when charging, or is there a significant risk in storage, at storage voltages?
It didn't catch fire until we opened it. The bag did it's job.
Storage voltage results in substantially less potential energy. I personally do not store lipos in bags, but I know people do. I don't believe it's necessary as every shipped lipo I've ever seen came in bubble wrap and a cardboard box. If there was a known issue with lipos in a storage state, they would take different precautions.
Personally, I believe the issues arise when:
1) The cell has been compromised - i.e. It's been physically damaged as in a plane wreck.
2) The cell has been over charged - i.e. Wrong charge profile used as every modern balance charge I've ever used limits peak voltage to 4.2v/c. So it comes down to misuse of the charger.
I use one bag per battery, always get the fold over flap or zipper types the batteries live in them unless they are in a flight, I never ever trust them seen way too many fail over time.
What I learned is to store my battery in a cinderblock box lol
lol.
This test was more to see how the bags would react, if it would work or not. If it would do what they say it will and actually it did. The Nail on the battery was just the way to get it started. Even though it's a good Demonstration of an airplane crashing and having the battery shove itself on the motor mount screws in the firewall, so there is some relevants to the nail. We were already talking about doing the other scenario Which is the overcharging of the battery or the incorrect Method of charging the battery, will she. I hope everybody got something out of this video I think it was interesting. And by the way, not all lipo fires are the same. So be very aware. They can be a lot more intense under different conditions. Just be careful.
They burn better and much hotter if you set them off by severely overcharging.
We considered the fact overcharging would require a purposeful misuse of a charger where a puncture could be unintentional.
That said, we intend on a v2 video where we'll put the overcharge to the test as well.
I had one caught fire while charging I immediately dropped it into a bucket of water . Fire went out in about. 5 seconds left it in there for 3 hours then dug a hole and buried it. I emailed local council for information on disposal . They replied that they had no information and told me to contact the manufacturer
Ocne they're burned out/fully discharged, they're inert. You can recycle what you can and toss the rubbish.
@@hayloft3834the bucket likely just cooled the battery fast enough to stop the reaction. With EVs there’s just too much thermal mass there for that to happen.
