I m customizing lead-acid battery at 48V, 44Ah, How I match cell chemistry in BQ34z110 as I didn't got any documents regarding cell chemistry matching? Also, it is better to use this IC or Bq34z100-G1 for lead-acid battery soc/soh determination?

Hello,

The BQ34Z110 is designed for lead acid batteries, I would use it for your application.

You can follow the FAQ E2E post on how to setup the gauge for different chemistry types: https://e2e.ti.com/support/power-management/f/196/p/733183/2707029#2707029?jktype=e2e

Same method as for bq34z100-g1 can be used in bq34z110 for cell chemistry matching?

Hello,

Yes similar methods can be used. The bq34z100-g1 uses the newer bqStudio software and has newer firmware, if you are starting a new design the bq34z100-g1 is recommended, after checking we recommend the bq34z100-g1 now because those reasons.
