I have a battery pack using the BQ20Z65-R1 to monitor the chagrining of the Li-battery. I got a Cell Overvoltage error and the charging was aborted. I am a novice and would like to know where to start looking for cause.
I was also told that BQ20Z65-R1 is being replaced by BQ40Z50-R1. Is this a direct drop-in replacement?
Thanks.
