Trick For Puffed, Bulging Or Swollen Battery LiPo Cells? DJI Mavic Drone.
Вставка
- Опубліковано 3 жов 2024
- After the expensive batteries on my drone began to puff up dangerously, I tried a simple trick to extend their useful life.
** 2 YEAR FOLLOW UP!!! **
Not only did this trick extend the batteries life, but they actually continued to improve (as far as holding their shape) after repeated cycles.)
Just passing it on to you.
Please use extreme caution if trying this trick, and let me know with a comment if you also had good luck with it? - Наука та технологія
I work for a drone survey company we use large LiPo and gas powered helicopter drones for survey, and we have several DJI drones including Mavic's, Matrice's, and a huge DJI Flycart. Along with the battery powered UAV's the survey instruments and electronics the UAV's carry are also powered by LiPo batteries, we have literally hundreds of different sized LiPo's stored in our workshop and out with crews working in the field on survey. If any of our LiPo batteries start showing signs of swelling and getting puffy they are disposed of straight away no question even if they seem ok when tested on one of our smart battery chargers, it's just too risky messing around with lithium batteries that are showing signs of aging, the cost of replacing them is nothing compared to the potential cost of the damage that a battery failure or lithium fire can cause.
" let me know if your drone catches on fire LOL" If my memory still serves me, fiery objects in flight seem to be a re- occurring theme in your life Walt! I was folding a plastic dry cleaning bag my wife left on our bed and my mind drifted off to a young Walt Noon in Riverside and the balloon escapades of the 1980's.... Which inspired this search, glad to see you are doing well!
Poked mine with a pin and it burst into flames and filled my house with smoke
I did a chat with DJI and they replaced my two batteries. I had to give them the serial numbers and take photos of the bulging and then I had to take a video of me soaking them in the salt water. And then two days later they emailed me a discount coupon for two free batteries and you use that at their store. I did this about a month and a half ago. I think they're worried about the bulging batteries and like you said having one pop out and crash the drone.
I recommend disposing of the battery properly
I just contacted DJI and they replaced 2 of my swollen batteries. Following their instructions it took 15 minutes!
Can you point me in the right direction for getting them replaced I've got 2 that swole up?
Same
@@MichaelNel123 I just went on ali express and they are being sold for 50$ and they arrive in like 3 weeks I bought one and it works like the original if you still need one id recommend doing that
Is proof of purchase absolutely necessary? I bought my drone used and therefore providing proof is difficult, though I don't see why it matters that I personally bought it. What should matter is that DJI sold it and that would be proven by the serial number.
Just get rid of it, it's not worth crashing the drone or risking your house, car or plane to catch fire during transport. Part 107 drone pilots (if this is the case) and recreational drone pilots should know better, don't tamper or attempt to solve problems with bad products that may endanger someone's life.
My DJI air 2 battery bulged at 65 cycles itself. The specs say it shouldn't bulge till 200 cycles. 🤦
mine Too
my bulged at 45 cycles
8 cycles, 13, 15 and 19. All Mavic air 2 batteries. Dji don't care.
I have a air 2s and it bulged at 30 Cycles second at 40 cycles!
Don’t mess with lithium batteries in any way. My apartment went up in flames from a bigger battery (without me doing anything to it in particular, just using the personal electric vehicle in a dynamic way, but no physical impact done), and it’s NOT fun. Thank god nobody died. Having been researching li battery safety a lot, I would say just dispose of them some official way, get a new one, and never tinker with them or force them if you have no idea what you are doing. They can easily catch fire and very badly so. I would’t trade the savings on the price of a new battery for the risk of a violent and possibly deadly fire. That said, even a new battery can catch fire but here there definitely is a sign of deformation so the risk is higher.
I can’t complain. I’ve had my drone for 1.5 years before it start swelling. I have 3 batteries, 2 of them extremely swollen, and one is just a tiny bit.
Now it’s been 5 years how I have it, so I’m scared that they will start fire… DJI should have policy to replace the batteries on half price if You return the old ones… I’ll never buy DJI product again!!!
I believe they will replace them I've heard anyways
"I can't complain" turns into "I'll never buy DJI again ..... lol
Dumb advice. It’s bulging because it’s about to die. Replace it immediately!
Respectfully/modestly… I began in applications of Li-poly in 1999 with RC aircraft.
“Puffing Lipos” have been our nemesis’ for 23+ years now.
Thank you.
i think a lot of the bulgin is jus tthe air in the covering getting hot and swelling up..... ive noticed my batterys are swollen when the drone has been flyin gand batterys drain and get hot, leave them to cool down and the swelling goes, this is proof its the trapped air in the covering that causes the problem.
just replace the cells its more safer than putting a clamp...
The right way is changing cells as the battery board and even then you must know how to reprogramme its cycles and production date
Yes prone to fire those bad those batteries can burst into flames in your closet or the trunk of your car....... Am I wrong that's one of my big concern's is with a Chinese knock off battery they can start a fire when they discharge......
In other words I'm really concerned about any lithium ion battery causing the fire anywhere anytime
Thanks. I was concerned as well. My batteries were straight from DJI. Chinese, but OEM. Will keep a close eye, and store defensively for thermal runaway. From what I've read, the bulging does not necessarily indicate impending failure.
Why would you keep using a bulging battery? That's a sign to get rid of it ASAP!
Not very sage advice I'm afraid. After many years of flying RC planes I can advise, any bulging Lippo batteries should be fully discharged ASAP (below 2.5v per cell) and disposed of. That of course is if you value your aircraft and or Home dwelling. At least keep them in a detached shed.
Battle of the bulge...?🤣
Have you reported this to DJI? They should not be selling any batteries that needs clamps to prevent them from bulging. If I feel like getting a drone I will not buy a DJI. Thanks for the video:)
It does seem to be a common problem, as I've seen many complaints. The batteries were a couple years old before this started, so well outside warranty. I don't mean the video to scare anyone off from DJI. The drone is nothing short of phenomenal! The reason I bought from DJI was that I crashed a friend's drone and DJI immediately fixed it and at a very fair price. That took my main fear of buying a drone away! Because, they are expensive, and you know you are going to have crashes. So, the fact they were fair and fast in taking care of my problems made a BIG impression on me. I would give their repair centers an A+, though their communication if you have issues can be slow.
One of my Mavic Air batteries recently started bulging like this, but it was already a 4 or 5 year old battery. My other 3 batteries are just fine. So don't let that deter you from a dji drone.
Huge red flag at 1:20.
Sorry, my english isn't very good. When do you use the clamp? After flying, during charging? Or After charging? Thanks a lot. I opend at on battery the cells with a needle 😮
Did u get any answet?
@@sphinxletherman8991 No, but I a Shop repaired two of my batteries
you clamp it then put it on charger but not too tight clamp, you can needle it but you need to be carefull and do outside
DJI replaced mine. My drone disconnected mid air because of that
Awesome job!!! Very nice video my friend.........keep going!
I'm going to try a heat gun, and then clamp it, maybe it will stay. 150 bucks a pop, and all my dji batteries are bulging. I did have one fall out of the sky, and that was probably why. Luckily I had the DJI replacement insurance
put mine in the freezer with clamps..24 h later came out super slim. waitnig for it to defrost. this is not going to end well at all
So... How did it end?
That bulge is hydrogen gas build up. Be careful with that, most batteries have advances to vent that off now, if you use items that still have this happen they are old tech.
good to know.
Great advice. I did this while charging next to the budgies cage, but the thing exploded and killed the budgie outright. Poor thing didn't stand a chance.
Please don't feel bad, as the wee swine would chirp all night, often making it difficult to sleep.
I now have another battery showing signs of bulging, so I might try your advice next to the hamster's cage.
🤣
ths is splendid .take care!;))
Thank you! Hope it helps!
i recommend using the bloated batteries as a makeshift incendiary grenade

Trying to keep my battery flat, I managed to short it accidentally, and the battery burst into a Ball of Flames, Be very careful with DJI battery packs, They are absolutely a waste of money and don't last very long. I am lucky if I had 14 Flights with the battery pack. My advice, They need to sort this issue out in the battery packs
Flat, what do you mean? Using the clamp method ?
Bruhhhh ....
You’re playing with fire literally, mine bulged like yours and luckily my fully charged one became hot after the charge so I tossed it onto the lawn from
10 feet away on grass and it exploded flames were 3 feet high . You’re liable to burn down your home .
Wow, mine did this yesterday. I was about to toss it across the lawn as well
Thank you so much for your video, this was super helpful for my bulging DJI batteries. :)
I have three and all three are swollen.
I pierced them.
Now they work perfectly.
Did you just pierce the plastic housing or right into the battery bag?
@@chain.driven
Pierce them from below.
Just the plastic.
a foul smell came out.
@@krassiyonov4804 that works too but there will be a chance of your battery failing mid-air
If this is your attitude, you should not be allowed to handle drones. Or anything else that can potentially hurt other people when not maintained properly. Grow up, dude.
He may not be giving the best advice about these batteries, granted. However, I don't think it has anything to do with immaturity lol. That was kind of a dumb thing to say.
this is extremely dangerous stop doing lol the puffing caused by gases inside of the lipo layers . Li-ion constructed often being able to vent out and built in hard case when case is soft it designed to be able to puff mean no vent even to out so if you push it probably you generate a microhole where the gases escaped if oxygene can go in later it will be a nice firework… It might work until the hole is very small for a while as the airflow is low but in time it is innetiveable if enough oxygen came in a small reaction will elarge the hole and more oxygene will come in an here comes the fireworks. the first thing you should do charge this thing in totally fireproof place lithium burns very high temp it will even damage concrete hard , and if it start in fear you might try to play a firefighter and that will cause more heat as this reaction will be even more hot if you add water the best thing you can do is to extract the battery from the case and insert a new one. I was trying to find tips how to build new bepop batteries as i have the same issue btw with puffing the battery carecteristic also change so it will be failing when you try to pull out more amps . I would like to now if your flat or drone cstched fire already …

@@dalegreer3095 haha Please write in hungarian… And from phone, but thanks for trying to read it
Nooooooo, do NOT do this. Replace the cells or dispose of the battery
