Description
The TP5100 4.2V / 8.4V Lithium Battery Charging Board is a high-efficiency charge management module designed for safely charging single-cell (1S) or dual-cell (2S) lithium-ion batteries. Powered by a switching-mode charger IC, it delivers stable, fast, and efficient charging up to 2A, making it ideal for modern electronics projects.
Unlike basic linear chargers, the TP5100 uses a high-frequency DC-DC architecture, reducing heat generation and improving efficiency—especially useful when charging from higher input voltages.
This module supports the complete lithium battery charging cycle, including pre-charge, constant-current (CC), and constant-voltage (CV) stages, ensuring battery longevity and safety. On-board indicator LEDs provide clear charging and full-charge status.
