mavic pro battery authentication failed

[charlyd]

Hi i made a custom mavic pro 1 battery.
it charges ok i checked it with dji battery killer. i also cleared PF bit back to green. now to me it looks ok.
i even connected it with a newly bought EV2300 interface. but one way or an other i am missing something because when i stick it in the drone i can not take of "battery authentication failure". what do i need to tweak to get this battery to work. it is a higher capacity battery kit(3) 11000mAh instead of 3850mAh. can somebody advise me on what to do or to check to fix this issue the controller keeps messaging " battery authentication failure ", can not take off. the batteries are connected to an original DJI battery bms controller board.

the batteries are connected to an original DJI battery bms controller board.

but is it a compatible one? Place the Battery on a LINUX machine.
Use the lsusb command in the Linux terminal to verify if your CP2112 device is recognized.
