Blew up a Tattu at our club just 2 weeks ago by dumping current into the pack at 20amps and at 30volts just using the main lead on an extention and telling the charger its a 8s lipo... without a balance lead....
Let me correct you, “if your battery is puffy” take it outside immediately and dump it in a bucket of water with a wet rag over the top, leave it there overnight away from any flammable objects (preferably in your driveway just in case there is a fire or it gets out of hand so others can see it). “If your battery gets hot while charging” either turn down the amperage but if it’s already lower than 1.5 Amps, (on most lipos) dispose of it immediately at the closest battery disposal if your lipo has any of the other signs mentioned in this vid. A lot of these videos fear monger beginners but if you take all the right steps your batteries can last for years and you won’t have to worry about it catching fire at all. Unless any of these signs have popped up and you have good habits you only need to check resistance bi-monthly if you want to be extra safe. Personally I have never checked resistance in the 3 years I have owned LIPOs but it’s definitely a good habit to get into for newer people. And YES ALWAYS CHECK AFTER CRASHING PLEASE!!!
18:47 ... so i'll just keep peering over the edge... (lol) glad to see it's not ALWAYS going to erupt, but yeah it can happen at anytime with a tiny short with the cell from an impact and the built up gas and self oxidizing scenario - poof. thanks for "taking one for the team" there
I've been using lipos since they were a thing... never had an issue. Last year I got 2x CNHL new batts. Put them on gentle charge in my condo.... (I'm in Thailand....there's no smoke alarms or fire protection or anything in the entire 300 unit condo). I was playing on my PC when suddenly couldn't see for smoke. I grabbed the charger threw out to balcony where one continued to burn itself out. Took me a few weeks for my lungs to recoup from the smoke inhalation. I still have no idea why one just went bang...especially brand new...and in parallel charge with another, which, to this day is still working fine. Since then I have bought a big steel toolbox, charge outside and never more than 2 at a time.
So basically Lipo battery are not really dangerous unless u keep an eye on the screen of your charger... A really good informational video broodie bro! Thnx...
I wouldn’t say not dangerous as they will always have a risk to them, but you can indeed lower the risk of things losing control by keeping an eye on them ✌️
My brother had a large battery explode inside, around highly flammable materials. Thankfully he got it outside before the other cells burst into flame.
A coworker of mine lost her house to a fire caused by a lipo battery being charged. Her son was charging an RC car battery in the garage, and no one thought anything of it. They decided to run some errands, and when they came back, the house was already fully engulfed with the fire department already on scene. The house was a total loss. Fire investigators determined that the source of the fire was what used to be lipo batteries on a charger. It took the better part of a year to get everything sorted out. Between lodging, insurance, losing nearly everything they owned, having to buy a new house... in addition to the obvious toll to her emotionally, which was clear to see every day when she came into the office. Just be careful. Know the dangers and take all the reasonable precautions, but enjoy the hobby. Best.
Very informative. Thanks. I think, For a 2200 mAh (2.2 Ah) battery, let's assume it's a standard 3-cell LiPo battery with a nominal voltage of 11.1V (3.7V per cell). Wh=2.2Ah×11.1V=24.42Wh
Awesome! I've heard mixed things about salt water, some positive, some negative, I'd still opt for a battery discharger personally as that way you know for a fact that the voltage has drained out before any corrosion can happen from the salt water.
Not necessarily a 'bad thing' but I would never recommend picking one up now. It's much better to use a charger that's a bit smarter, shows you the voltage and resistance of the individual cells, and also allows for higher amps when needed. 4-button chargers are still okay, and if you have one you can certainly still use it, I just found a world of better change when I switched to a budget 'smarter charger' ✌️
The old iMaxB6 was a 4button charger, that had a repuation for miss-reading cell voltage, overcharging cells and starting fires. Smart Chargers, like Hota, are better for your lipos, more intelligent, easier to use, and less likely to miss read 👍
i have a habit of charging my lipobatt after resting for an hour even if it has 70-80% of charge am i doing it right? is it safe for my battery? because i have charging it in 22% empty stage that takes 4-6hrs to charge
I know first hand, Take care of your lipos....I had 4, 6s lipos go bad, all today...one cell in each is bad...4 lipos in one day, because i did not take cre of them last year when I first got them! geat video buddy
What if I need to walk away and don't want to leave it charging? Can I stop charging it and not damage anything? Obviously not use the battery until fully charged.
i keep mine in a spare ammo crate now... try to keep them indoors for temperature control when not in use, and i try to keep them discharged, also id have like if u explained the SIMPLE relationship between Watts, Amps, and Volts, and the basic math used to calculate them, took me 5 min to learn this in flim school, and its VERY useful info for ALL work involving batteries and electronics, also your video assumes we are using a High price, smart charger, i think by that point, your already aware of the things presented in this video, however i NEVER SEEN a smart charger, most people use what they need, dont use more than 3s, well buy a 3d 20 dollar battery charger, and so on, theres no resistance numbers however the chargers do have built in resistance controls, again this is useless to thosse starting in the hobby and not buying super expensive chargers
@@BrodieReed Thanks a million. I like to be safe, but I like to get my craft back into the air ASAP like everyone else. Impatience does not mix with LIPO!
Lower c is safer, and will do less damage to the chemistry than 1C, but takes longer. I generally charge at 1C at home and 2C if i'm in a hurry (typically charging 20 packs on a pair of 4way Hota F6 chargers)
this video is the reason i went for the avata instead of anything else xd im hoping to upgrade in the future for some gerpc with a o3 unit maybe? is there anything better?
haha, well at the end of the day, the Avata still runs off of LiPos, so the risks do still apply. Albeit the safety features included with DJIs smart batteries do take a lot of the numbers side out of it. Most larger FPV drones can have an O3 unit now, the BetaFPV Pavo series is a pretty good place to look I'd say if you've already got an Avata. Have a look at the Pavo35, I'm testing it out currently and am loving it: bit.ly/48gHOJ7
You’d be working with other live cells. If you shorted one of them it would most likely cause something dangerous, and your hand/face would be close to the battery as you work on it. I wouldn’t recommend at all
I rly wanted to get into fpv drones after watching days worth of videos but this one kinda makes me consider not to get into it, sems like alot of things to think about and remember
Not if you get an DJI Avata 2 🙂 - They use Lithium Ion batteries which are as safe as a mobile phone battery - Less to think about if you’re concerned and less fuss.
@@cnewland82 true but that one with the fly more pack is 1 355 USD for me with the wierd single hand remote so quite abit more expensive than one like those in the video
Unfortunately I didn't have to poke a hole in mine. Flames about 1.2 meters high. Scary shit. Learn your batteries kids

That's fun! Usually get a real nice fireball when overcharging 💥

Did you over charge it? Did you put it near any highly flammable material? And was it crappy
@@HugothegreatYT Was sitting on a marble top wall unit. It was 13 mins into a charge at .6a rate. Crappy? Obviously, it burst into flames.
@@LostCloudx4 hmmm maybe you wher putting to much volts
I love your videos!! They're well thought out and put together.
Glad you like them! Thanks ✌️

At least you remembered what a lipo was called
Im gonna start selling Brodie Bars if you aren’t careful
@BrodieReed don't tempted me, do I get them free?
I’ll give you a discount of $2 off your first purchase
@BrodieReed I'll take it (I love how we are haveing a convo in your comment section)
Why not aye ✌️
Very deep cover on battery topic. nice 😍 I throw it into a bucket of salt water to dispose my batt
Awesome! I've heard mixed things about salt water, some positive, some negative, I'd still opt for a battery discharger personally as that way you know for a fact that the voltage has drained out before any corrosion can happen from the salt water.
4 button charger? Is that supposed to be a bad thing?🤔

Yep! I put another one to rest today as well lol, mistreat em, they'll mistreat ya back 😅
What’s the best way to extinguish a lipo fire if one does occur?
You can't really extinguish a lithium fire.
how do you charge your xt30 lipos?
Those black and purple batteries are the same ones that exploded on me lol
What if I need to walk away and don't want to leave it charging? Can I stop charging it and not damage anything? Obviously not use the battery until fully charged.
Wow never knew it was that dangerous! Thanks!
Well, I'm super glad to hear, they certainly are a serious topic!
Wait why do u charge it to 4.2 when there is 3.7 volts per cell? Am I missing something?
how did you come up with 4.20v charge
Doing an experiment with no shoes on. 😂
Just gotta send it you know 😎
@@BrodieReed the newzealand way o.s.h approved jandels used in severe conditions
Absolutely, I also use my safety glasses for all experiments too 😎
ReelSteadyGo and the gopro Hero 12 will work , or is the missing gps data making ReelSteadyGo not work anymore with the hero 12, would you know ?

Is it marginally safer to charge at slightly less than 1C, or is this just wasting time?
I would say the slower the safer technically, but 1C is a pretty standardised charge rate which weighs up time to safety
@@BrodieReed Thanks a million. I like to be safe, but I like to get my craft back into the air ASAP like everyone else. Impatience does not mix with LIPO!

So I land at 8v?
Depends on how many cells, lipos want to above ~ 3.6v per cell. When flying you can go down to ~3.5 and it will recover to 3.6v on its own.
Why can't you replace a dead cell?
You’d be working with other live cells. If you shorted one of them it would most likely cause something dangerous, and your hand/face would be close to the battery as you work on it. I wouldn’t recommend at all
Christ just drop the ground.
