TP5100 5V 2A Lithium Battery Charging Module

The high-efficiency TP5100 switching charging module is designed for lithium-ion batteries. The board accepts a wide input voltage range from +5V to 18V, so it can be powered by a variety of AC adapters and other power sources. The PCB includes a pad for setting the 4.8V charging mode by soldering a bridge (solder short connect). A built-in LED indicator shows the charging status at a glance: the red light stays on during active charging, and the blue light signals that charging is complete or that no battery is connected. Features: Product type: switching module for charging lithium-ion batteries Specifications: input voltage from +5 to 18V, charging current up to 2A, optional 4.8V charging mode set by shorting the solder pads (solder short connect) Indication: dual-color LED indicator (red during charging, blue when fully charged or in standby mode) Purpose: safe and efficient charging of lithium cells, with overheating and overload protection
