Hi

We are planning to use BQ27542-g1 for our POS design. Our  battery specs as below. Please confirm the following queries.

1. Can we use 2S cells (3.7V/5200mAh) battery.

2. We have got the CHEMID of our battery is 1280 with BQ27411-G1A.  Can we use same CHEMID with BQ27542 IC or again CHEMID generation is required.

3.  BQ27542-g1 ----this is one time programmable or can we re-program multiple times.
