Adjust the R6 resistor value to adjust the output voltage, and adjust it according to the charging voltage marked on your battery.
Adjust the R8 resistor to adjust the charging current according to your own battery capacity.
The thickness of the board should be as thin as possible to facilitate heat conduction between the layers.
When charging at 3A, the chip generates a lot of heat and needs to be properly dissipated and a heat sink needs to be installed.
