Hi
the issue i have is the battery is dead after it hadnt been charged for a sometime. the DJI software has locked it from charging. i have tried directly charging the cell brining it to voltage then trying to charge it wouldnt work, i then got the CP2112 board and accessed the BMS to unlock it, it does everything but unlock the chip so im thinking if there is a way around this or if someone has sucess with a similar situ. Thanks

If the cells have gone below 2v they are goosed, plus even if you replace them with new cells you won’t be able to unlock the BMS

I checked the cells and they were both at 2.5v then when charged via bypass it came to a good 3.6 each. So i need to clear the pf on chips basically. Its rubbish Dji have locked it.
