BQ27750: How to setting the value of Qmax and Design Capacity?

Part Number: BQ27750

Hi TI experts,
How to setting the value of Qmax and Design Capacity? To follow typical value by battery spec or minimum value? As I know, Qmax will update during learning cycle, but Design Capacity always fixed. SOH is calculate by FCC/Design Capacity, I don't know these value are typ or min, would you help me to check? Many thanks.

hi Che yi

Qmax will be updated by the gauge when learning completes. you do not need to modify it. Design capacity should be set to the typical value specified in the manufacturer data sheet.

thanks
