9.2.3.3.2 Fast Charging Current

The fast charging current is configured to 2000 mA (Fast Charging: Current) by default, which is conservative for the majority of 4400-mAh battery applications. This should be configured based on the battery configuration, cell manufacturer's data sheet, and system power design requirements.
