MAVIC 2 battery error
First I would like to thank you for the tools. Second I encountered an error while trying to repair my Mavic 2 battery. Any help will be highly apreciated. Here it is what error I got:
root@raspberrypi:/boot/dji# ./comm_sbs_bqctrl.py -vvv --dev_address 0x0b read BatteryStatus

The program works because when trying to read the other battery that I have it can read it ok! This battery functioned ok since 2 weeks ago when for no reason stopped working. I tried to revive it by charging-discharging it but when plug into the drone I receive the same message : Battery signal error. I understand my BMS is kinda heavily broken and I am looking for any solution that would help me get the BMS up and running. The battery is charging when plugged into the charger. Otherwise is not starting at all. If I remove the battery while charging it can operates for couple of seconds but it shutdown almost immediately. Thank you
