TP5100 Li-ion battery charging board
TP5100 Li-ion battery charging board with CC/CV charging and protection features—ideal for Li-ion/ Li-Po DIY projects and portable devices.
The TP5100 Li-ion Battery Charging Board is a high-efficiency charging module designed for Li-ion and Li-Polymer batteries. Based on the TP5100 IC, it provides constant-current/constant-voltage (CC/CV) charging, ensuring safe, reliable, and fast charging with automatic termination when the battery is full.
The board supports input voltages up to 8V–30V and adjustable charging current according to battery capacity, making it ideal for DIY battery packs, portable devices, Arduino/ESP32 projects, and IoT applications.
With overcurrent, overvoltage, and short-circuit protection, the TP5100 charging board ensures safety for both the battery and the power source. Its compact design and easy-to-use interface make it a popular choice for hobbyists and professionals developing battery-powered projects.
