Many thanks for producing this video as it saved me the cost of a new battery. I had to open the battery and used my bench power supply set to 0.05A constant current to get each of the three cells to 3.7V before trying to remove the PF in BMS with the Arduino Nano. Purchased the AN especially for this fix and it was a great learning experience and will no doubt open up a few more projects to enjoy.
what happens if you use 5v phone charger with a TP4056 to charge the cells?? did I screw them up? because I got them up to 4v but the arduino IDE is stuck on Unseal/FAS ...
First of all, I would like to express my gratitude to the developer who generously shared the Maverick Air battery recovery code and provided an easy-to-follow explanation. My battery had not been used for about 6 months, and one of the two batteries had low voltage, causing the battery management system (BMS) to lock the battery, preventing it from charging, and the green LED was not functioning, as described in the video.
Following the instructions in the video, I purchased an Arduino Nano and the necessary cables to prepare for coding. Since one cell of the battery had dropped below 3 volts, I disassembled the battery and individually charged the three cells using the 1-cell lithium polymer battery charging function of an RC battery charger. After charging the 3 cells to the same level of 3.7 volts, I prepared the program and files as instructed in the video. There were many trials and errors in the process. Even though I followed the video, the file did not upload, and the red transmission LED on the Arduino Nano did not blink. Despite trying to change the transmission speed, as suggested in other comments, the file still did not transfer. Finally, changing the COM port from COM4, as mentioned in the video, to COM7 allowed the upload to succeed.
After a successful upload, following the remaining steps outlined in the video resulted in the battery coming back to life perfectly. I then charged the recovered battery with a DJI charger and successfully completed a flight. Since the voltage of the three battery cells in my case did not drop significantly, there seemed to be no impact on the battery performance. If not using the battery, it seems advisable to charge it at least once every three months. Charging until the green LED shows two bars should be sufficient; it doesn't need to be fully charged. I hope everyone can successfully recover their batteries.
Was able to recover two batteries with your guide and software. Thank you very much.
Thanks a million!! This worked great for my 3 batteries and my drone is back in the sky!! 😊
Thanks for this great instruction video. It felt like a miracle to see the green battery leads flash like in the old days. At first I encountered some trouble with Xloader, but uploading with a baudrate of 57600 instead of 115200 was the solution (took a while to find out 🙂). Also the use of TP4056 was a succes . I bought 2 for nearly 1 euro! Connected it to the usb out of the Mavic charger and within a few minutes I had charged the 3 cells from 2.40 -1.21-1.51 to 2.85-2.82 and 2.89. This was enough to properly run the HEX. Thanks a bunch ! While typing this the battery indicates it is fully charged. Greetz from the Netherlands.
I can confirm, using the default baudrate (57600) worked for me. I was able to restore 2 batteries using arduino nano clone.
Very good my friend. It worked like a charm. I just had first charge the cells to at least 3.2V. Thank you so much for sharing this work with the community!
Great program that has worked for me. Due to a lack of battery power, I also had to open battery case and manually charge each of the 3 Lipo batteries. The Ardunio UNO R3 (ATMEG328P) worked fine after trying the software on a NANO "every" ATMEGA4809 chip set.😅
Thank you, Circuitschool
it works perfectly after opening the battery pack and recharging each element alone above 3.7V. Well done and thank you !
How did you take the top off of the battery and what charger did you use ?
If you get stuck keep retrying and or adjusting wires I Took some retrying multiple times but I finally got it to take. I had issues with the xloader device settings not seeing my device so I ahead to change it to the cc01 and not the cr03. Even though it said the 4854 bytes were uploaded.
I finally was able to get it to work.
The two batteries that weren't responding had to be opened up (found a pretty quick disassembly video on youtube) and I used a TP4056 board from Amazon (you can get like a 5 pack next day for like 6 or 7 dollars.
I soldered a bunch of breadboard jumpers to all the pads on the board, and powered the board with the 5V out from my Arduino Uno.
Placed a push button switch in line to the power to the TP4056 board so that I could control when I was actually charging.
Hooked up a voltage meter across the Bat+ and Bat- leads on the breadboard so that I could read the voltage of the battery.
Cycled on and off charging for a few seconds at a time by using the button, and then periodically checking the voltage. All 3 cells charged pretty quickly from about 2.7ish to about 3.2 before starting to slow. Charged all 3 cells from one battery up to 3.5 (took a WHILE), and then decided to test the unsealing script again and it worked. Finished charging in the charging cradle once it would recognize.
Charged the second battery's 3 cells up to about 3.07, and the script was also able to recognize and unseal the battery, so try with about 3.05-3.1 volts instead of waiting a long time to try to get to like 3.8 as the guide says.
Other than that, it works.
Would love to see the code, interested in what's going on behind the scenes.
Would you have a link to that video you mentioned to show how to take the case apart?

You're really awesome, thank you!👍You saved my Mavic Air 1 battery.🙂
I had to use the TP4056 charger, charged the battery's 3 cells up to about 3.6V, and after the script was also able to recognize and unseal the battery. Xloader wasn't working at 115200, so i just left it in 57600. I used an Arduino Nano clone (cheaper) and it was fine.
Greetings from Hungary!
what happens if you use 5v phone charger with a TP4056 to charge the cells?? did I screw them up? because I got them up to 4v but the arduino IDE is stuck on Unseal/FAS ...
Dji Mavic air battry cell hold 4v in each cell so it okay
Normally 3 cell battry fully charge 12.6v but Dji battry hold 13v
MUCHAS GRACIAS. SI FUNCIONA. BATERIA RECUPERADA. SALUDOS DESDE CHILE
Thanks for sharing this! How long did it take you to charge the individual cells with TP4056?
To have a good contact with the battery, use metal tape that we use to make lithium battery packs (this takes soldering very well) cover with a welding film on 8mm, solder one end of a strap wire above
cut with scissors to have the pin of the strap like a flag (the flag being the ribbon).
you now have a connector that ensures a good connection.
I think it must be possible to do it with a piece of tin can (I haven't tried)
So I did everything perfectly but the battery light still didn't come on even when pressing the button. I had to take apart the battery. No need to drill holes or anything crazy. Using a pen knife you can carefully ubdo the back of the case by working near the connector. It will open like its on a hinge and you will see the BMS board at the top. There are three cells that each should be over 3 volts. There are 6 total pads. 3 on the right and 3 on the left. Each two pads should show you the voltage using a volt meter. Find the cell that is low. Usually one will be under 2 volts. Make sure to take note of the positive and negative side and take a 4 volt battery supply and connect Pos to pos and neg to neg. Do this for only a few seconds using some wires. No need to solder anything then check the voltage. Keep doing this until the voltage is over 3 volts. The program should now work and you can charge fully using the DJI charger.
Thanks to OP and comments here like this one for the help!
I had to open the battery and get the cells up to 3.6v before I could reset the battery using the arduino as in the video, although I flashed the arduino via the command line on my mac using avrdude, installed using like so:
> brew install avrdude
plug in your arduino to a usb port and use this to discover its location via
> ls /dev/tty* | grep usb
> avrdude -p m328p -b 57600 -P [INSERT YOUR USB DEVICE LOCATION HERE] -c stk500v1 -U flash:w:Mavicair_pfreset_circuitschools.hex
2 batteries saved, thanks!
Hi, do you have it for a inspire 1 battery? Thank you
hello can i use this your work on dji mini 1 battery that hasn't been charged for 2 years?
Can you change battery capacity with this too or do I need cp2112 to change capacity values. I’m trying to make a Dji mini 2 battery with 3500mah lipo cells
What is the board that you're using Do I need that or can I just soldier the pins
Will this method work for the dji mavic pro. I work in a hospice and we were gifted one but the batteries are non responsive.
We are going to use it to check the gutters and roof of our building, that is if I can get it working again - not sure if it works though so not wanting to buy a new battery etc.

Hello quick question waht is the white board that the tp 4056 sits on?
Hi, your codes work wonderfully
I've tried resetting the cycle number and work perfectly.
Is it possible to customize the cycle number to 7 or 10?
Thanks
My battery total voltage was 7,8v (3v, 3v and 1,8v). Charged it with balance charger and first it didn´t work, but when i powered up the "charger side positive pin" jumping directly from battery it worked. BMS does not seem to power up itself again from battery side even if voltage is enough high
Youre awesome, thank you! it worked on my spark. xloader wasn't working at 115200, so i just left it in 57600 and it worked. And then in arduino serial monitor, 115200 worked
hi, i have dji spark and arduino uno. I need to reset the battery, it seems that cp2112 is needed on the internet to reset it, but I don't have it. can i do it with arduino uno can you help me?
@@enestelkes I'm not sure what cp 2112 is, but an uno will definitely work. I just looked up what cp2112 is and I don't think you need one because the uno should have i2c compatibility. a nano/pro mini is practically the same as an UNO, and that's what I used
@@nickkirastoulis4617 thanks, I tried it for Spark with Uno, but it stays on "Unseal/FAS ...", I don't know what to do.
by the way i did 57600 as you said but "uploading" remained, so i did 115200
It works! I'm using all the same setup except Arduino Uno. Also the charging of battery when it's stuck at "unseal" was a lifesaver! Thanks so much :)

It would be good if you tried to open the battery of a Mavic Air 2 and transfer it to the battery of a Mavic Air 1 to increase its flight time, since one has more milliamps than the other.
PD: Good video 🎉
I would like to do the same but with MAVIC PRO 1 battery. Is there an .ino file ready to upload to arduino and use a software to unlock PF?
ciao posso usare questo tuo lavoro su batteria dji mini 1 che non e stata caricata per 2 anni?
Hello can u help on a phantom 4 battery
Here's how i charged individual cells: I used a regular battery charger designed for AA batteries, connecting two wires with positive (+) to positive (+) and negative (-) to negative (-). Then, I checked all three cells by referring to images online that indicate the positive and negative terminals of each cell. After checking the voltage of each cell, I discovered that one out of the three had a voltage below 2V. I charged that particular cell up to 2.11V (while the other two cells were around the same range, 2.11V to 3V). Charging just that one cell was sufficient. I reconnected it to the chip, ran the software, and it worked like a charm.
Similarly, with my second battery, the voltages were similar, except this time the bottom cell was below 2V. I charged it to 2.11V, ran the software, and everything worked perfectly. The batteries now look brand new and function flawlessly.
Did you have to take apart the battery to individually charge them? If so, is there a tutorial on how to do that?
Is this possible with the Dji Mini 2 battery?
Thanks
Hi! Is this method works on DJI Spark?
Does it also work on mavic pro batteries... ?

Hola , tienen el método y código para una batería dji mini 2 ?
Hello, do you have the method and code for a dji mini 2 battery?
Obrigado pelo vídeo tutorial de como restaurar. Comigo deu certo da seguinte maneira:
Tinha a versão do arduino ide atual e não deu certo. Tive que baixar a versão 1.8.18 igual a do vídeo.
Outro detalhe a taxa de transferência o baud comigo não deu certo o valor de 115200, funcionou com a taxa de 57600(xloader). Tive que alterar a taxa no arduino uno para 115200, pois de fabrica veio em 9600.
E por último Tive que abrir a bateria e carregar cada célula até a voltagem de 3.85v ou superior para voltar a vida. Pois quando fiz o procedimento, não acendia igual a parte final do vídeo. E ao elevar a voltagem para os 3.85v, ao ligar novamente no computador, a bateria acendeu novamente e estou conseguindo carregar novamente.
Obrigado🙂👍🏼
great video, do you think this can be used for the batteries of the dji spark ? thanks and greetings from belgium -Domi

Genial, me llego hoy un arduino nano supongo chino por mercado libre argentina, parecido a amazon o ebay de eeuu. y funciono al segundo intento, cambiando de puerto com e instalando los drivers ch340g.
Hello friend. For some reason I'm not being able to download the hex file completely. And xloader is failing to upload bytes to Arduino. Any suggestions?
Hello guy, can you please send the code to configure my arduino (nano) to a usb to a SMBUS ?
Thanks for the video ! I'm trying to repair my 3 DJI Mavic Air batteries, but i'm stucked on "Unseal/FAS". I've also bought a lipo charger and charged the cells to a correct voltage, but nothing changes. The thing I'm doing different from the video is using a "DCcduino" Arduino UNO Chinese clone, should this be a problem ?
may be there is any connection problem, please check the wiring and try. It works with any arduino clones.
Can you reprogram the BMS for custom battery for example if i get some 4000+ mAH batterys ? Do you have a tool for that ?
My cells are at 1.6v , 2.5v , 2.5v so i guess its dead. And if im going to replace them i was thinking of getting the best cells i could get
Helou friend work for mavic 2 mini ?
Is the code work on mavic pro battery? Thanks
Hello, I uploaded the code but got nothing in the serial monitor(using 115200 baud rate)
Normally I dun comment to RUclips videos. But this tutorial just saved 2 of my Mavic Air batteries. The HEX file is zipped and password protected. The password is reveal on the website. Go check it out.
hi i am stuck in unseal fas even i chargfe the battery in 2nd step all cells is 4 vlots now why nothing happens if unsealing
Thanks so much, it works with uno and Dji Mini 2 battery as well.
Thank for the info: I am trying to reset a battery of my Mini SE (same one as Mini 2) but I'm stuck at "Unseal/FAS ..." Now I know I need to recharge the cells
The same code that was used in this video also works for the Dji Mini 2?
@Angelo-krto, Yes, after balancing the cells, batteries were still locked. I used Arduino uno and the code on two DJI mini2 batteries. Both are working now properly.
@@ludmilkostov4067Okay thank you for replying.
I’m trying to make a custom battery pack for my Dji mini 2. I saw some 3500mah lipo cells on aliexpress specifically for the Mini 2. If replace the original lipo cells from the pack with the 3500mah cells will this same method work for unsealing & sealing the pack?
And can you rewrite the new 3500mah capacity in the bms for the drone to recognize the new capacity?
@@Angelokrto Usually BMS's don't care about capacity of the cells, but voltage and balancing. I saw youtube clips where people put additional battery pack connected with wires to the original BMS. Unsealing should work, but I haven't tested it with new batteries (I charged the original cells separately to the same voltage, without de-soldering them from the BMS).
Hi, i tried this past it works. Now i replace the cells and tried this again but now its stuck at unseal/FAS no blinking leds.😢 please help
Hi, How can I get the code for mavic 2 pro?
How do you open the Mavic Air 1 case/cover without marking the plastics much, to get to the cells.
It has strong glue pads sticked hardly, You need to pull slowly to avoid damage, but still we get small scratches on platics, better use an old credit card or guitar picks

With many thousands of Mavic Pro and Mavic Pro Platinum owners having the (now) very common 'Battery Error' in many of our original DJI batteries, have you given any consideration to creating a data upload file for both these Mavic batteries similar to what you have done for your Mavic Air battery so we can use your Arduino procedure? I for one, am very interested in obtaining such data file specifically for my Mavic Pro Platinum battery; even if you charged a (small?) fee for doing this for interested Mavic Pro / Pro Platinum owners! There is total confusion on what Pins 1 & 10 in this battery actually are; e.g., in the only "reliable" Mavic Pro / Pro Platinum complete pinout [[which are completely different for all other Mavic models battery pinouts]] I have come across on the Net, Pin 1 is shown as RXD (UART Receive) and TXD (UART Transmit), BUT do Pins 1 & 10 also actually correspond to the SCL & SDA pins respectively (or even vice versa), and if so, which is which?? I am not knowledgeable in UART understanding! I know there are SCL & SDA locations on these batteries internal circuit board however, you have to essentially destroy the battery casing in getting access to this board - also, it is a time-consuming exercise and one that carries a fairly high "danger risk" for the inexperienced (and experienced alike) to attempt dismantling the battery casing! I've tried the CP2112 board procedure which failed every time stating 'battery not connected or similar error message' and come to the conclusion Pins 1 & 10 (SCL & SDA) are NOT connected to these UART designated external pins???? Appreciate your (or any of your viewers) advice here, please. I have three Mavic Pro Platinum batteries and all three show absolutely no puffing or damage or other adverse observations and all three can be discharged (for the defective DJI battery via the USB - battery adapter) and charged fully! The only difference is that the defective battery shows the "Battery Error" fault which, therefore, prevents the drone from flying!!!! Clearly, IMO, the issue is solely that the PF Flag is blocking the battery from operating!!! Having received the "Over current flashing code" during charging this battery wherein the charger actually put out more current than it should have(??) and repeatedly does this for the few times I repeated this process, I no longer use this charger and am waiting on delivery of a new one! Greatly appreciate your help in resolving this wide-spread issue with Mavic Pro Platinum batteries, please. Cheers from Down Under and Seasons Greetings to all.
