96 V Battery Management System

I have a projcect BMS for electric vehicle. It will be 96 voltage. I am thinking to use nearly 27 battery packages. I decided to use passive battery system according to my resear ch. I need some intagrated circuits that can be the best intagre. I found a couple like max14921, ltc6802... Do you have anyone who work on this topic or on these intagres ? Your suggessions are really important for me. Thanks you from now.

I'm designing a BMS board base bq76940, and i hope it can archive a 300V+ BMS system by serial connect a few board.

I researched bq series. But, specially texas instrument products are really hard to programme and use. Did you look or research ltc6802. I like this. But, I am still not sure.
