Hello.

Is it possible to use the BQ76952 to connect two LiFePO4 battery packs in series for battery balancing?
The batteries are two LiFePO4 (12.8V) 20000mA.

Hello,

BQ76952 only supports a minimum of 3S, however, the BQ76907(BQ76907 data sheet, product information and support | TI.com) and BQ76905(BQ76905 data sheet, product information and support | TI.com) can both support 2S for LiFePO4 batteries and offer cell balancing.

Please take a look at the datasheets and other supporting documentation to see if they suit your needs!

Best Regards,
Alexis
