Hi,
This may be basic question about battery pack. Basically VSS pin is connected to cell -, but in this case, the supply current of bq40z50-R1 is not flowed sense resistor so supply current can't be measured. I understand that this should be current measurement error but it's very small (tens of uA) so this error is ignored. Is my understanding correct?
