When I bought my first cheap drone a few years ago, I had absolutely no clue about the massive dangers of the lipo batteries it came with... looking back now, I did basically every red flag thing you could possibly do... I left them charging unattended all the time. I had absolutely no safe charging station, I just kinda laid them on my bed or desk, surrounded by combustible materials, while charging unattended with the cheapo charger that was included with the drone. I'd leave my drone and batteries in my car in the middle of summer in North Carolina. After a few months, one of them started to puff up pretty badly, I had no idea what that meant, the only reason I stopped using it was that it became so swollen that it could no longer fit into the drone battery compartment. I'd sit and play with the swollen battery, pushing around the bubble under the protective layer. I was so naive... Looking back now, I'm EXTREMELY fortunate I never burned down my house or car. I really wish they did more to explain the risks of careless use when it comes to lipo's.

Man, this video got me thinking: I need to put some protective measures in place! Thank you for the warning!

We forgot to mention that a very big threat to lipo batteries is charging them incorrectly as NIMH or NIcad. It is obvious and many chargers prevent this but charging a Lipo battery as the wrong type or cell count can push the battery's voltage beyond its safe limit. Even trickle charging it is a huge risk. Charging needs to shut off when the max voltage is reached (4.2 vots per cell)

Thank you for putting this out there! I have just begun in the world of RC and had no idea that this was a possible threat.

Just bought Traxxas and the store I bought it from sold me 2 3S Batteries without even warning me of any of the risks. I did the research myself and I'm glad I found these videos. Didn't know these were such a huge liability. I'm coming from the nitro world so these are a complete shock!!

Wish more people would do videos on this. Thank you for tackling this subject. Looking forward to more information in this series.

Really great videos about lipo battery safety! These things can be very nasty when ignited! Keep you, your family and your property safe!

This is one of the best videos you can watch on KZfaq imo. Especially if you happen to own a LiPo or five+. Absolutely essential information for keeping your family, yourself and your belongings safe.

Thank you for addressing this issue! I recently bought my first LiPo (2s) for my new gen8. Funny thing was, I asked my local dealer more questions about LiPo safety than the gen 8 itself. lol

Just purchased my first RC and I was hesitant because of the batteries. Very informative. Thanks

Thank you for sharing the knowledge. I have just bought my son first electric monster truck. Totally had no idea this could happen. Cheers.

Thank you for making this video, I did not realize that what safety measures I have currently are not enough.

I charge in my Weber kettle barbecue. This is thanks to the amount of similar warning videos. This one is really good because it goes over the main causes of fire so you learn why you need to mitigate.

Just learned something new today. I will create my own isolation charging station today. Thanks for the tips!

WOW, never realised how bad this could be, thank you for this information, I have just ordered a BATSAFE for charging and storing my batteries.

Thank you sir for this informative video! I’ve been looking to get my first hobby grade RC car the last couple days at my local hobby shops. Before my first visit, I watched a video about what not to do with lipo batteries and one about the chargers and my head about exploded! They scared me from going with a brushless/Lipo truck like my friends and the hobby shop guys recommend. Thankfully they all explained it a lot of this to me and could answer my questions. I now feel OK with trying to use these batteries, and I happen to have some cinder blocks sitting next to my garage that will come in handy setting a charging station up in my garage.

Again great video, but maybe you can do a video about how to safely dispose of them cause there is a lot of bad information out there about that and you seem very thorough!

Thanks for the refresher on this! 💥 ***THIS*** Should be MANDATORY for ALL individuals using these sorts of batteries. Safety first folks every time 😎

Thanks man, got my first lipo couple weeks ago since then I was using NiMH. It’s a hard case 5000mAh 2s. Life saver about battery!

Thanks for this video, such important information could save our homes etc !

Excellent refresher video.

Wow! I am a newbie haven't had an RC car since I was a kid. Just ordered a RC truck and lipo battery/charger from my local hobby shop online and after seeing this I just ordered a lipo fireproof charging/storage bag. on Amazon. Thanks for the info kind of nervous now but better to know the potential dangers.

Great video and VERY INFORMATIVE. After watching this I've been thinking about returning my lipo batteries that I bought for the first time. I've never used these batteries but after watching videos on these batteries I don't think I wanna keep them. I wished that I would of done more research before buying them. I can't have a ticking time bomb in my house. I think the danger out weighs the good in them. Just because they out last and run longer doesn't make it a plus and then have to worry about fires. I rather run my Ni-MH and NI-CD and be safe. Thanks for the video bud. Thumbs up on the video. 👍

Great video. This is information that needs to be out there. Thank You

You opened my eyes to this issue and I tank you! Amazon is selling a nice Ammo crate for a little under 30 Canadian $ Thank you. I have a family, 2 kids. This is not to be taken lightly in my opinion.

This is such a risk. I just bought my first LiPo, but have had LiFe batteries for a while. I'm not sure if there is the same concern with LiFe packs, but anytime you concentrate that much energy in a small location, the potential for disaster is there. I watched another video on LiPo bag tests, and the thing you need to realize is that once started, a battery fire will continue until the chemical energy is totally consumed. The fire also produces a lot of toxic gases. Those hot toxic gases ARE GOING TO ESCAPE your container no matter what it is. Steel ammo case, LiPo bag, concrete block, whatever. So you need to think about where the stream of hot gases is going to project out of the container, and make sure there are no combustibles in that area. Also need to think about what your battery container is sitting on. Needs to be non-combustible also. I like the idea of a cinder-block container. They have lots of mass, so they absorb a lot of the heat from the fire. They are porous, so the gases have a large area to escape from (directly through the cinder block material), so you don't get a huge jet of fire out of a small opening, like you see happening on some of the envelope style bags. Also, as the gases pass through the cinder block, they are cooled so by the time they exit the other side of the cinder block wall, they are not hot enough to ignite combustibles. As I write this, I'm thinking I should design a low-cost (DIY) charging and storage station. Great video. Solid facts.

Quite sage advice!! It amazes me how many people STILL don't know safe Lipo handling! 😳😖 I mean, we don't want to incite RIOTS... It's still a rare occurrence - but it CAN happen!! Like anything powerful, they demand respect. I try to NEVER stress my Batteries when charging. Even if the Label says that it CAN charge at 4S... I'll NEVER charge ANY of my Batteries more than 1S!! I'm never in such a hurry that I'm willing to risk it. Ever. One thing worth mentioning - if you do have a puffy Lipo, DON'T just throw it away. It'll just explode somewhere else!! Put the defunct Battery in a tub (pot, pail, ect...) of VERY salty water for at least an hour. It will stabilize the chemical reaction. THEN dispose it properly. Thank you for this! Carmine ✈🚂🚙

This was a good video, the public needs to know how to be safe. I have 2 that got damaged and I will not charge them. One was a brand new 5s the blue one you have early in the vid. One crash and that was it. I'm terified of it.

Someone might commented this already but I don't wanna read all the comments below. I just wanna add one more thing that is very important. Fire extinguisher for class C fire. Although there is a class ABC fire extinguisher, the best one should be the C for the specific fire since every class of fire has one best extinguishing agent. Thanks

Amazing video! Very informative!

Don't get complacent. Assume the worse will happen, then use every precaution. Over charging is dangerous. Like he said: never trust the charger never leave the lipo while charging.

Wow. A new Dharma Initiative video. Nice upgrade on the video quality. Thanks Pierre.

I would have never known about these dangers if I hadn't watched this video thank you so much, sir. I have just placed an order to get some safeguard bags

Great video. Thank you for sharing this insight on batteries. This has raised my knowledge level more on storage and charging. 👍🏾

Always interesting. ..thanks man

I appreciate your videos ❤️ please keep them coming 🙌🏽

Good video and good advice. Yeah, I do not know what I’m doing so I balance charge all the time.

I almost bought an Arrma Kraton @RCreview until I saw this video. I had no idea how dangerous lipo batteries were. While I’m sure any motivated RC enthusiast could do this pretty safe, it seems like a total headache to deal with and not worth the risk if you make a mistake. RC companies should really find a safer solution and less hassle free solutions with safeguards built in, like other electronics. Hopefully the future will get better for RC batteries, but until then, it’s not worth the effort. Thanks!

Thank you. Thank you so much. So many useful information and guides. I really appreciate your work. Thanks again.

thanks so much for this video!! I have made some changes for extra safety according to your suggestions!

Spent a lot of time reading about lipo when starting back up in rc. So careful now when charging/ balancing/ storage. Also invested in a few Batsafe boxes, well worth investing

Very intetesting..thank you for your time and the vid..ill look for part two ...ron..ill be putting my lipo.s in a old metal ammo box today.. 4 cell.s

Great video, thanks for sharing this valuable info. Definite food for thought, important to highlight the risks which seem small until something happens. Better to be super safe than super sorry. Looking forward to more in the series.

Great and informative video! I went to Home Depot bought 4 cinder blocks for 4 bucks and 4 24'' ceramic tiles maybe 8 bucks. In my garage the blocks sit on the tile on the concrete floor and during charging I place tiles on top. This will help contain the fire but does nothing to minimize the large amount of toxic smoke that's released. I also have a bag of sand which will put out the fire quickly. I'm also looking into Spectrum's new smart charger and smart Lipos, the are pricey though.

Great advice. I would also add to charge them at 1c rate which is slower but it's safer and the battery doesn't get heated. This is how I always charge my batteries.

Thank you for these tips.

Thanks for this informative video. Stopped me from buying a (probably) sub par battery and cheap charger just to save money. Not worth it!

What a great infomative video. Thank you.

Nicely explained. well done.

Hey Francis, my wife was wondering if it would be okay for us to store our lipo batteries in our shed outside, or would that be too cold overnight for the batteries? Thanks! Great channel man, thx for all the videos

Excellent lecture.

Traxxas has good quality control on their batteries. I also should say I have never used any other batteries. Every Traxxas LiPo I have had has never swollen on me or ignited in 5 years. But I'm very careful with my LiPos so I: -Store in an ammo can (no rubber gasket) -Only use the EZ Peak ID charger -Always attend during charging - Always let the battery cool and put into storage charge after every run -Always balance charge, always -Maintain battery temp during use. Feel the battery, if it feels as warm as the hot water in your house shit it down immediately.

😁👍 BATSAFE lipo charging storage box best thing you can buy for your lipos!

Thanks for the info! I might need a 2nd lipo safe because I got a few new batteries and they need to be safe any safes that I can use?

Great Lipo safety video. Thanks for making it. Im new to the new Lipo RCs and i was a bit nervous about these things. But i have and do everything you mentioned so i feel better.

Great video that every RC hobyist should watch

Some batteries also include aluminum plates. This option makes a compromise between fully exposed and fully enclosed. As for incidents, I've damaged a few cells without venting, and I had one cell of a 4S blow - but thankfully it simply left a small char mark. I've had more near-misses with old laptops than with my RCs. That said, I'm counting my blessings. I have a pack in front of me that the balance charger has to work pretty hard to re-balance. Not flying with this one anymore, it scares me.

well put! great video!

Thanks for the explanation. Should I get rid of the battery with first signs of puffiness? Or some swelling after use is normal? And can I salvage the good cells, or is it a bad idea?

Great video Dude. Thanks!

I really like the channel you're the man

This is so damn important. Literally today 2 Lipos just burned down in my car while driving and i was so lucky that I had a fire "resistant" bag. The bag still started burning but it really prevented the worst. In the end only the bag and my backpack was damaged. You should better be prepared beforehand. I would spent lots of money in advance to pretend such happenings, in order to safe even more money, to not burn your house or car down. Better be safe than sorry!

This video opened my eyes to the dangers of this hobby. I'm considering this may be a little to much stress for just wanting to fly a few airplanes. Having the thought in the back of your mind of where the battiers are, and the conditions they are in. 😒

Thanks. Good info.

Good video man.

Lithium polymer does not catch fire because of air, when you damage the cells or change it's form, thin layers of cathode and anodes touch each other and short, increasing temps in some places, which catches fire. And since any battery is flammable, it expands fast and blows it up

Great video 🇨🇷🇺🇸🤜🏻🤛🏻

Thank you so important to know, seems very risky and just a few know about this.

thank you. going to buy a lipo case now. Wonder if they make ones that are protective but also carry an rc

Also buy a Lipo alarm. Set the alarm to 3.4 V When driving your RC car or flying your plane. When the battery discharge to 3.4 V the alarm goes off so you know it is time to get your battery out. Stay in safe limits.

Nice video!

Thank you that was very helpful

So charging a 3s lipo battery.. do u charge it lower then the rates volts or just at the rate voltage....and do so in a fireproof bag..

Thank you for your info

I had to run scared three times before I finally learned to immediately get rid of puffy lipo’s NOT WORTH IT! Didn’t loose anything besides a few charred spots on charger and work table. Whewww!

Thank you very much for this info, i charged my 3s 5000mah in my wooden wendy house earlier, wish watched this first, anyway ive taken it out now.

If you can, it would be interesting to see how the LIPO sacks do in preventing fires and other problems. Just a thought.

Great info. Thanks man

What do you think about sky RC chargers? I have the e450. Thanks for all the advice.

You're the RC Professor!

Thanks for the video. Very important information that everyone needs to know.

Thank you.

I don’t have a garage and it’s usually over 100° on my patio. Do you think it would be okay to store them in a metal insulated thermos while out of town or could that be worse and go boom!

Good info.

Really appreciate your video. I would like to know where can I purchase a metal or a stainless steel big box for my batteries I have 8x 4S 6700 TRAXXAS lipo battery’s and the 2x 3S 14,000 and 2x 4s 10,000 Spektrum lipo battery’s i use the Traxxas and Spektrum smart chargers as well as the Lipo charging bags when charging them I normally do it on my kitchen island however, looking at this video that is a good idea to put it in my smoker I need a metal box or stainless steel to travel and keep in a safe place since these batteries are pretty dangerous, big and powerful

I have been using lipo battery's for 15 years. I have always understood the dangers of lipo's. However I have not understood the severity or the fact that when a call is damaged mear exposure to the air will cause an explosion and fire. I have been using a Venom multi chemistry charger and lipo batteries for Nine Years. Yes those batteries are nearly 10 years old now. I Have Been Lucky! I say this because though they are hard case batteries, at least two of them are bloated, and have been for a long time! I have thrown out some lipo's because they stopped working. I take them to the recycling center where they have a storage box for battery disposal. I have been running Traxxas 4tec 2.0s since the cars hit the market two+ years ago. Do to the Traxxas ID system of batteries and chargers that is what I have been using. I tend to buy cheap,BUT I have never used cheap lipos. The Traxxas system prevents me from from doing so. That is a good thing. I have been tempted to buy cheap lipo's but have not done so. I have what I believed was a safe charging station, but watching the video has prompted me to do some improvements, And stop using my old Venom batteries and disposing of them properly as I have always done. Ten years is a Good run for them, time to let them go!

Thanks, good video.

The batteries we bought for my girlfriend's Armma Nero are puffy as hell, they barely fit in the battery area's in the Nero. They've been like this from almost new. I know there in a bad state, I store them in a kevlar bag that's in a metal military ammo can to limit the amount of oxygen and potential damage. No Idea why they've been like this either? I have some pretty high end chargers and balance them regularly. I also use these in my Airsoft guns as well and haven't had issues with those, except one that didn't work at all when I bought it. These batteries always make me nervous and I've done electronic repairs for 30 years and have a decent amount of understanding of them. I think they should be more stable than they are. I can tell you from experience, never buy the cheep Chinese Lipo's are so incredibly inconsistent and not worth the risk. This is a great and need I say a necessary video to watch for people who use these batteries just for the heads up. I know of two people that actually lost their vehicle's to Lipo fires because they didn't know they batteries were compromised . So for me , the only time my Lipo's come out of the Lipo bags and ammo cans is for actual use. They are stored and charged in the bags and cans because I absolutely don't trust them. There are other better alternatives, but are more costly. Usually the same chargers for Lipo's have programs and settings for them as well. Sorry for the long post, again great video's and information, cheers!

This is making me reconsider even getting into RC......

How do you balance charge a battery with usd micro cable

Jesus man I'm new to this stuff, I'm sleeping next to my tank right now with one of these batteries, time to move it,😂😂😂😂😂 thanks mate.

Do i have to worry if the lipo battery is low batt and i just store it on the shelves is there tendency to explode even though im not charging it and how big is the damage .. because i have lipo battery for my drone and im gonna be out of time for a while do i have to throw them away and just buy a new one when i get home

Thanks man I appreciate. Now I'm more worried abt my puffy drone lipos.

From what I understand you need a class D fire extinguisher for a lipo fire. I looked into a Class D and they wanted about 600 bucks! I wish the fire departments or Gov would subsidize some of that cost somehow to make safety affordable. Also apparently extinguishers have shelf life's and need to be replaced every so many years. I've found that the best place to store lipo's is a unused fireplace with the flew open and the batt's inside ammo cans or fire proof containers etc. This way they are away from heat in the summer and in a fire proof location with a vent.

I have a question. My drone just crashed into the tree. Fortunately, LIPO battery didnt explode but the plastic cover is cracked. I just wonder how to dispose it properly and if there is any chance of explosion even if I just keep it somewhere, without touching it. Also, can LIPO battery catch on fire even when isn't being charged? Many drones come with a suitcase and after every flight I take the battery out of the drone but keep it in the same suitcase for storage,

I just bought a wltoys 144001 for my 12 year old nephew.... he is not getting it. I'm glad I didn't give it to him yet !!! It has no name 2s 2600 mAh packs . And a cheapo USB charger. I left them both unattended in my bedroom on my computer for 3 hours at a time. Thanks for this video

I store my batteries in a sliding tool box.. i always charge on top a metal surface... only had 1 that burnt up during charging.. i had alot of brushless esc catch on fire about 4 so far lol

If you still reply to comments i just bought a drone and it is a tiny lipo battery. I charged it it got to max and then the light turned off about 5 mins later my sister said whats that smell? It was the battery. But i used a UK charger head on it. The smoke came from the charger port to the battery head or wher the light is. Was the problem the UK power head or something else? Im in EU btw. And should i still use the battery?

Army ammo box is good, just be sure to latch the lid. Find good size ones for $15+ at surplus stores, peddler malls, gun stores and shows, ect.
