You can adjust the R6 resistor value to adjust the output voltage and the R8 resistor to adjust the current, and adjust it according to your own battery.
The heat generated when powering 3A is huge. A heat sink is needed to cool down. There will be time to release a second version to solve the heating problem.
It generates a lot of heat and needs to be installed with a heat sink. The charger needs to have a 5v3a power supply. According to actual tests, there is no problem at 3a maximum power for 30 minutes. Once the heat dissipation is done, there is no big problem.
The second edition has been updated
Attached is the ip2312 specification sheet.
