The device will be pre-programmed with a fixed max current limit of 3.5A. Everything runs automatically and will charge up to the max capability of the connected USB PD power supply if the max current output limit exceeds the input power supply. Lower current limits can be programmed as well.
Charging current is decided by the USB PD Source capability. First, it checks the available voltages from the source, then selects the voltage that will result in the highest efficiency for the regulator based on the number of cells. For instance, using a 30W supply with a 20V 1.5A (30W) capability and a 4s Lipo battery at 15.0V. The charging current will be 30W/15.0V=2A. As the battery voltage increases, the max charging current will decrease. 30W/16.0V=1.875A.
