Hi Ian,

The customer needs to use the GPCCHEM tool to find the best chemistry id.

Here is an example.

Device / Family #3

Generic Chem ID Device/ Voltage/ Chemistry max DOD error, %

3230 bq27426: (default) 4.35V LiCoO2 2.75

3142 bq27426: (ALT-CHEM2) 4.4V LiCoO2 3.02

1202 bq27426: (ALT_CHEM1) 4.2V LiCoO2 11.37

Best generic ID 3230

Also, the customer needs to create a golden image by themselves.
