Hello Akshay,

Yes, this could work. You would need ~23 3.2V cells to have a 72V pack so yes you could use 12 channels of one BQ79616, and 11 of the other. (please note we have the BQ79612 as well which is a 12-channel version). THE BQ79631 could act as a UIR sensor and monitor the current and control the switches/relays/do insulation measurements.
