Green Smart BMS: Intelligent Battery Management System

The project originated when the author purchased an electric motorcycle for his daughter and replaced its original lead-acid gel battery with a lithium battery pack. Due to the lack of smart, cheap and easy to configure lithium battery management systems on the market, the author decided to make one himself.

Schematic PCB

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.
