How to Recover Dji Mavic Air battery
HTML-код
- Опубликовано: 1 май 2022
- Start from the simplest way, stepwise recover a locked Mavic Air battery due to prolong storage.
We don't need to fully disassemble the battery, just open the top cover to expose the electrodes of the cells. Basic soldering technique will be required.
Extra hardware:
CP2112 board will be needed to unseal the battery.
Extra software:
DJI battery killer, that use with the CP2112

after not using my dron for over 2 years. my 2 batteries where not responding, nor charging. today I got the CP2112 board. last night I opened my first battery and charged to 12.5v 300ma. and this morning the second one. I then tried deleting the flags but was not able as the video describe I jumped the battery cell to the + side of the package. connected to the dron using the USB and was able to update the firmware on both, then able to delete the flags. now I am charging. great to have found this article. saved over 5000 Mexican Pesos on 2 batteries
Can you show where to jump it? I’m kinda confuse i have the same issues with my battery.
Hello sir iam from Philippines how to get the link of dji battery killer tools software..can you help me get a software..thank you
Wish I had known this was possible last year. Thanks for the time and effort. 👍
Great tutorial. Thanks. As mentioned in comments, I opened the battery case easily and it kept the whole thing as new once closed back. My batteries were dead low. I had to charge them for a long time (I went ended up charging up to 12.5v to be able to do the soft update. I did the soft update with the DJI GO 4 app instead of DJI Assistant. That unlocked my batteries as well as unsealed them at once. I still went through the DJI Battery killer process at the end to be sure. Now all 3 are all good as new. You rock DSJay!!!
Thanks for making the video, worked for me. One cell was down to 0.6v !!! but after connecting to a charger and getting the pack up to about 3.5v per cell, I was able to unseal and then finish off on the original charger. I found it was not too difficult to open the battery case.
THX for this great Video, you're the man. One of my Mavic Air Batteries was totally dead, no loading no signs of life.
I ordered the CP2112 Board, but it couldn't communicate with the battery, but a working one did.
So I opened up th eBattery, one cell had 2,2V the other two 3,2V. So I loaded it wth a 12V and 200mA, till it arrives around 12V.
After that the CP2112 recognized the Battery and I could do the work with the DJI Battery Killer.
After that I could load the Battery at the charger and now it is fully loaded.
Greetings from Toronto. All I can say is - Thank you! Very clear step by step instructions. I was able to resurrect my dead Mavic Air battery. I had to use that DJI Assistant-2 to (re)load the firmware, though. But, worked - in the end.
I had 3 batteries. 2 didn't need the firmware trick but the last one did. So weird.
Thank you I will tray this, I am waiting for the CP2112, I was able to open the case with a thin screw driver, there are 3 clips on each long side and 2 on each short side
Thank you! It’s working again!
thank for the video fixed all batteries, but the casings come apart easy no need to drill
Thank you so much. Amazing video!
You helped me a lot and saved me $100. Thank you.
Hi, where did you get the wires with the correct connectors from?
You don't need to Dremel and hack at the battery case, it comes apart quite easily with a small plastic wedge or gently with a blade in the corner to get it started.
Couldn't get the batteries to charge beyond 12V with my power supply, so the killer couldn't read the info and I wasn't able to force update, so I decided to try and read *while* the external power was still connected, and hey it worked. Thanks for helping me save $200 👊
Same problem the battery stocks at 11 volts what did you do
it works like a charm for my battery. Thank you mister...
i did not drill the battery cover. i just removed it by releasing clips on the up side.
using the software failed at unsealing step. so I charged the battery using the same charger. however the charger stopped at 11.38V.
it was enough to connect the battery to CP2112 board and do unseal and clear PFs.
I recharged the battery using dji charger and tested all cells. measures show 4.35V for every cell. I don't know why.
Now it's up to mount the battery on the drone and do some stress test before a flight.
😄😄😄
What "same charger"?
@@jameslovell8682
dji charger
Where to get the software! Please help
@@prabalbhatia469
just search for dji battery killer in google
Cool video, Thanks a lot!
This worked perfectly for me - thanks for the instructions.
The casing can be separated fairly easily, though, without drilling into the top!
how did you open up the casings without drilling?
Yeah, how????
@@ZenMountain small screwdriver theres 3 clips on each long side and 2 clips on short sides. It's fairly easy to pry open.
Exactly. Small screwdriver to create the gap, slide it all along the edge to loosen it. Then with the small one creating the gap insert a large flat head that you can twist with. If you work your way all around gently it comes apart with minimal tool marks and less chance of damaging certainly versus drilling! I recovered 3 x Mavic Air batteries today by manually charging them and using an Arduino to unseal/clear pf/reseal. Can be done with a cp2112 adapter as well. The BMS wouldn't respond over the serial connection until about 12.10-12.20V so be patient.
Thank you so much!!
From what I understood, the BMS disconnects the positive source from the connector to essentially "seal" the battery pack. Bypassing the BMS, and connecting the positive source directly to the connector powers up the drone, and allowing the BMS to be unsealed by the drone. I wonder if this technique works on all DJI's battery packs and drones. This can probably allow you to replace the cells, and reactivate the BMS.
Gracias saludos de Uruguay pude recuperar un bat nueva compre un dron que lo trajeron de España y una batería nunca le cargo al dueño anterior lo compre y me propuse ver si podía recuperarla ....ví todo tu vídeo compre el cp2112 se conecto seguí los pasos que hiciste y quedó espetacular 19min de vuelo al max 9% tuve algunos inconvenientes torpes como falsos contactos en el cp saque la ficha que viene y soldé los cable al cp y use los pines de las ficha del cp las soldé a la punta de los 3 cables para conectar ala batería y un éxito muchas gracias
how can i find software could help me friend? is it for mobile download?
Superb video, and DJI really rip you a hole with these small batteries costing $140 in Australia , a decent power tool battery 4 x the size is cheaper than that!
1:04 thanks a lot for sharing will definitely going to try, from what these small yellow, green and purple cables called
Hello, thank you for sharing such valuable info. I live in South Africa and where there is no Cp2112 board available, is there any other alternative to reset a battery for MINI 2?
i got one of ebay from china
I'm happy that it can be fixed. I'm just too dumb to actually do it.
Thanks
I have the same drone batteries and i just used a small thin plastic pry bar and got the battery packageing apart without having to drill.
I'm getting my battery to 12v and forcing the firmware update. Each time I try it's gets to 99% and then it says error, battery must be more than 50% charged. How do you get around this problem? How long do you guys find it takes to charge the battery with the low charge .5A current? Thanks.
Did you find a solution? I am having the same problem
Красавчик!
Great video, so useful and clear....🤔😏😀😀😀🇬🇧...However you didn't click on the "Reset Chip"....This would have allowed a full charge on the charger without opening the battery up?..😏🤔
can you list other adaptors i can use available in uk please
What are the wires types needef
can we use a CP2104 adaptor please
Thanks for the tutorial! I'm also getting an "Error: could not perform smbus read 0x00". I changed to all ground pins and tried on 3 batteries (2 dead and 1 working). Same error for all ground pins for all 3 batteries.
Hi. Hope all is well. This is also happening to me. Did you ever find a solution to this problem
@@orlystreco2911 I found the solution. I just did a 10 secs video how i fixed the error - ruclips.net/video/x_MaDqLKW8g/видео.html

will it work for TB50 batteries?
i ordered the cp1221 chip and nothing, then i ordered hobbie charger and charged by method shown in video, well not as shown in video cuz he drilled holes in battery i just opened battery up and charged as shown in video. took less than 30 mins to bring 2 dead batteries back to life. Only problem is i have 2 new dji batteries on the way. Thanks for the video.
Thanks for the video. I finally received my CP2112 but the only battery killer software I could find won't open on my PC. Any guidance or alternate sources would be much appreciated. Cheers
Can I use ftdi for this?
Is there any tips you can offer?
graet video... do you know if works with the tb60 matrice 300 battery? thanks
Are you will to do this for us people that have no idea
What version of windows are you using, 7 or 10?
does it work for Mavic pro too?
speak man!!
I'm just wondering, what driver are you using for the CP2112? I've just purchased a CP2112 and when I connect it to my computer, I'm always getting this "Unknown USB device (Device descriptor request failed)" And thus unable to run the battery killer app.
I've tried uninstalling the device driver. But everytime I plug the chip into the computer again, i still get the same message.
Just hoping if you can point me in the right direction for the correct driver. Thank you very much.
There are 2 exe files. Make sure your clicking on the correct one. I first recieved error also. Then tried other exe..on wi dows 10
What are those wires called so I can buy them?
Hi are you doing this for other people who have not the competenc/ tools and wisdom to do this like me for sure not for free and for sure it could not work with garantie but at this moment i could not find someone who can do it for me so are you able to help ?
So my mavic air battery was not charging no lights, not turning on nothing dead. So got the board, connected to dji killer but got the error, nxt opened the battery as shown above shouldered as above in the video still error, nxt what I did is disconnected the negative solder and rather then bypassing , connected the board to the battery ( cp2112) still showed error, while connected to pc touch the positive soldered wire to the positive point to 1st left on the battery terminal and then on pc read info again and it should come up. Then do as above. Thanks
BIG QUESTION - If on connects power between first 4 pins and last 4 pins on drone - WILL IT FLY?? (probably not...)
Such an amazing video. Thanks so much for this. I have a question, My battery has stopped at 11.3 v and I tried charging it several times for around 5 minutes but seems it's not charging. Is it damaged or do you have any idea on this? But I charged it from 2.9v to 11.3v thanks to you!!. If you can give a help, thanks so much!! Also I was using laptop charger. But it didn't get heat I was monitoring.
may be you can try to update the battery firmware with 11.3v to see if it can be unlocked.
@@dsjay It didn't work bro. Charged to 12.8 v but when it's updating software says 50% is not enough. I think there is more than 50% but it says so.
Same problem.
No need to click "Reset Chip" ??
I have a problem, after connecting the cp2112 to the battery, connecting to the program, the programmer burned out for the second time. just goes CPU smoke in cp2112. The battery works, but the cp2112 no longer works
Very good ! does anyone knows if is used tungsten solder to sold the cells ? A friend sad to me that the solder to use has to be for aluminium.

Thanks for a great video! Can you tell me the names of those connector cables I would need please? Thanks
He used DuPont Cables
Is it okay to update the firmware for dji mavic air?
Hello, Thank you for the video. It helped me a lot. I managed to get one of my Mavic Air 2 batteries working, but the Mavic Air 1 battery has one of the cells discharging very fast after a charge. Do you know how to fix this??
ruclips.net/video/buiQl98vvP0/видео.html
This recovery method simple allows the BMS to clear and start using it again. If one of your battery cells is damaged from being discharged and won't hold a charge there's no way to fix that short of replacing the individual Lipo cell which would have to match size, etc... Not worth it likely.
I try to connect mavic air battery but show " ERROR : could not perform SMBus read 0x00 "
How to fix?
Please..🙏
As many other people including myself it looks like there in no solution for that problem.
Hi folks..I am getting an error saying unable to ‘Unseal/FAS’ Battery..any idea how to resolve this?
Wouldn't it be cp2102 instead of CP2112?
Where can i download the software?
thanks. how about dji spark batteries?
I think DJI batteries should work in the same way. The CP2112 works with several DJI batteries. We just need to know the structures of different type of DJI batteries so that with minimal crack down the battery case to preserve the battery.
Video para mavic pro 1 please
Hello there, I’m using the same charger but it stops when it reaches 11.58v and I cannot push it to 12v. I haven’t set any safety stop or whatever
If it reached 11.58v, you can still try to update the firmware as I shown. My first attempt was also at the similar voltage as you.
link ?
it is applicable in DJI mini 2? i removed the battery and change the cell but badly .it didnt turning on. even i connect it into CP2112. but can read . even my other battery cant reat. it is the battery software problem?? thank. 💚
Sir cp2112 adapter bay
Hola de Uruguay.... compre un cp2112 en china viene en camino mirando las preguna y repuestas comentan sobre el cable el mio viene sin cable ,,, consulto es un cable USB comun verdad que sea una entrada para el cp2112 y otra para el puerto de la pc ? no es un cable especial no?
you can try to search "Dupont wire". it makes you easier to connect the battery and the board.
When I click "Read Info" I get "ERROR: Could not perform SMBus read 0x00" are my batteries broken? They are about a year old but weren't used for maybe 6 months

i get this message ERROR: Could not open device can anyone help me
Same issue here, did you ever find a solution?
It is work for MP1? Answer please
So far I don’t have MP1 on hand for trial, I think theoretical, DJI batteries work in the same way. The question is does the CP2112 work with MP1. You may need to search it. You can download the DJI battery killer, there will be sample pictures of connection with dji batteries.
Is it worked for your MP1?
I have the MPP with 3 batteries, 1 year not used. I charged their cells individually up to 4.00V. But no luck with CP2112. It shows "ERROR: Could not perform SMBus read 0x00".
Would appreciate if you can help me.

dosnt work on mavic air one battery just comes up SMBus read 0x00, even tried it on a working battery and it comes up the same
Worked for me and my mavic air one batteries..... your connection has to be good. I actually soldered the connection to the solder points inside the battery as I had to open it up to charge it.
Will you do mine for me please 🙏
Where did you buy cables for cp2112 ore does it follow when you buy cp2112? Thanks
Search “Dupont wire” you can find it like Amazon, and Aliexpress.
My CP2112 did not come with the wire.
We don’t find dji battery killers apps

Hey, fix my battery!
Tôi muốn mua bo mạch CP2112 và phần mềm . vậy anh có thể Gửi cho tôi và giá bao nhiêu $ vn đống ?
thank you for your reply. May be you can get the CP2112 from Aliexpress or Amazons. For the software, you can check the 2 links posted in the descriptions. You should be able to download it. However, #Michael Maklaud told there is a new version.
what do you use to charge the battery? can you attach link here? thanks🙂
It was B6 Lipo charger. It is not a must to use that kind of charger, even old style NiCd charger will work. We just need to carefully select a safe mA value and keep monitoring the battery during charging will be ok.
