Battery reset pointer appreciated #298

Closed nc1914 closed 1 year ago

nc1914 commented 1 year ago

Hi. I’ve followed the excellent youtube video using a PI to access i2c, and reset the low battery flags CUDEP and CUV, which has resulted in PF=0, resealed my (Mavic Pro) battery - but it still acts like it’s dead. I have no leds, no response to the switch or the charger. Have I missed a flag please? It’s charged to 11.5v now, had gone rather low in storage… Many thanks for your help, Nathan.

No idea. The documentation of BQ30Z55 is available, with that and the ability to read status of the chip it is possible to figure out what was tripped. Closing.

Hi, thanks for your reply, eventually I found out that holding the power button down for 30 seconds reset the bus and the battery is now working normally again.NathanOn 9 Jan 2023, at 13:33, mefistotelis @.***> wrote: No idea.
