1 year ago Hi mefistotelis, I'm currently facing a rather peculiar issue with one DJI Mini 2 battery. The PF flags are definitely off, the XCHG and XDSG on, and the battery isn't functioning - it blinks three times and stops. If you have any suggestions or advice regarding my battery issue, I would be grateful. Thank you in advance!

Battery not charged - all leds flashing 3 times per second. I replace battery elements and when use this command:
$./comm_sbs_bqctrl.py -vvv --dev_address 0x0b -c BQ40z307 -b smbus:1 --short monitor StatusBits

I think the problem is [ TCA=1] and [ TDA=1]. No problem to unseal BQ chip, but can't find how to clear this flags. Any help please
