This Lithium Ion battery charging module is perfect for charging single cell 3.7V lithium batteries such as 18650s. Built around the TP4056 and DW01 integrated circuits, this charger module is ideal for charging 18650, Li-Ion, Li-Polymer, and other lithium batteries. The module charges at a 1 Amp current, switching to constant voltage charging mode when nearing the 4.2V cut-off voltage. With built-in protection circuitry, this module offers more than just simple Li-Ion charging. If the battery voltage drops below 2.4V during discharge, the protection IC disconnects the load, preventing battery damage.
