Looking for a method to monitor a 24s battery with 3.7v Lifepo4 cells. Does anyone have any suggestions for a path to get this accomplished.

Hi Richard,
You could monitor the cells with 2 BQ76952 using a stacked design such as was used with TIDA-01093. The bottom part's coulomb counter could be used for watching charge, BQ76952 does not do gauging, your MCU would need to determine SOC. You could use a stack level gauge such as the la BQ34z100-G1 for gauging if desired, see TIDA-010030 as a reference. With a stacked design you will need to combine the FET control signaling if using it, low side control can be simpler, see https://www.ti.com/lit/pdf/sluaa84 for some low side drive circuit ideas if needed.
