BQ76PL455A-Q1: Cell and IC Stacking.

Part Number: BQ76PL455A-Q1

Hi,

I am using LiFePO4 cell with 19S, understand from previous thread that as long as each cell (and the max stack voltage) are within the datasheet spec, any battery chemistry can work. I would like to get further advise for the below.

  1. For stacking design how’s the arrangement of the battery cell in 19 series? Will it be 10s & 9s combination or 16s & 3s combination?
  2. For stacking design is there any issue during assembly? For example to connect the 1st stacking IC first follow the 2nd stacking IC or vice versa.
