How to Recover Dji Mavic Air battery

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

[@andywu7583]

Can you show where to jump it? I’m kinda confuse i have the same issues with my battery.

[@blacksmithz1]

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

[@bfr0g]

Wish I had known this was possible last year. Thanks for the time and effort. 👍

[@dkbbass403]

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.

[@cobra71ger]

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.

[@Plafimodon]

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!!!

[@PremMenon]

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.

[@Unsta]

I had 3 batteries. 2 didn't need the firmware trick but the last one did. So weird.

[@myseattle]

Thank you! It’s working again!

[@rafaelcontrerascabrera6059]

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

[@todvanced7842]

Thank you so much. Amazing video!

[@scottgiles7566]

thank for the video fixed all batteries, but the casings come apart easy no need to drill

[@redone4684]

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. 😄😄😄

Hi, where did you get the wires with the correct connectors from?

[@Mr.SisterFisster]

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.

[@M.R.C.R.]

Cool video, Thanks a lot!

[@whiteobama3032]

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 👊

[@azilsorveto7180]

Same problem the battery stocks at 11 volts what did you do

[@KerrynBartlett]

This worked perfectly for me - thanks for the instructions. The casing can be separated fairly easily, though, without drilling into the top!

[@daniellegabriel3382]

how did you open up the casings without drilling?

[@ZenMountain]

Yeah, how????

[@shortaj1966]

@@ZenMountain small screwdriver theres 3 clips on each long side and 2 clips on short sides. It's fairly easy to pry open.

[@Unsta]

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.

[@gerardopereyra3989]

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?

[@viniciuss.nakadomari8798]

Thank you so much!!

[@patrickjeromeobaldo2450]

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.

[@stevegreen7638]

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.

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

[@swetch80]

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.

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.

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.

[@user-ot6jk8jo9z]

kzbin.info/www/bejne/mKbMgp9vbduphpI

[@Unsta]

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 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.
