Open source lithium battery management board, charging 5V2A, discharging 5V/1.52A or 12V/0.76A

This DIY LiPo super charger can charge a single LiPo battery and protect it from overvoltage, overload and short circuit. In addition, it can boost the battery voltage to 5 V or 12 V. The boosted output voltage is protected by an "eFuse" IC with a maximum output current of 1.52 A at 5 V and 0.76 A at 12 V. The charger part of the circuit requires a +5V power supply, which can be connected via USB-C, or simply solder two wires to pads on the PCB. Additionally, other connections can be soldered to pads on the PCB or use individual pin headers.
