Li-Ion cell charger TP5100 1S/2S 4.2V/8.4V up to 2A with protection

The TP5100 Lithium-Ion (Li-Ion) cell charging module is a flexible solution for 1S or 2S systems, offering a customisable configuration by soldering a jumper on the board. It allows charging with a maximum current of up to 2A and is equipped with an LED to indicate correct operation. The jumper marked SET allows the module to be put into charging mode for two cells, raising the charging voltage to 9V. This compact and economical module features protection against overheating, current overload and undervoltage. In addition, it offers an output for connecting an external indicator LED, making it an ideal choice for small, cost-effective projects using one or two Li-Ion cells. Specification:

* support for 1S and 2S Li-Ion cells (soldering the SET jumper switches the module to 2S mode)
