## Description

Charging module for 1S or 2S Li-ion batteries, compatible with 4.2V cells and 8.4V packs, quickly selectable via SET jumper. Provides fast charging with programmable current up to 2A, accepts wide 5-18VDC power supply and allows the connection of a bicolor LED to display the charging status. Includes integrated protections for safe operation in DIY projects and industrial applications.
Lithium-ion battery charging module in 1S or 2S configuration, with TP5100, compatible with both single 4.2V cells and double 8.4V cells, with the possibility to select the battery type via the SET jumper.
This module is ideal for applications requiring fast charging, with a current of up to 2A, which can be set by replacing an SMD resistor.
The module can be equipped with a bi-color LED indicator (red/green) that provides real-time visual feedback on the charging status.
Specifications:
Supply voltage: 5-18VDC (recommended up to 15VDC)
Compatibility: Li-ion batteries 1S (4.2V) and 2S (8.4V)
Charging current: Programmable between 0.1A and 2A
Switching frequency: 400KHz
Indicators: Bi-color LED, optional
Integrated protections: overcurrent, undervoltage, overheating, short circuit, reverse polarity
Pre-charge current: Programmable between 10% and 100%
Dimensions: 25 x 17mm
Usage:
Connect the power supply to the module input (make sure the voltage does not exceed 18VDC, we recommend a maximum of 15VDC).
Select the charging mode (4.2V for one cell or 8.4V for two cells in series). The factory setting is for 1S. For 2S, bridge the pads marked SET.
Connect the battery to the module output, respecting the correct polarity.
Attach a bi-color LED if you want to display the charging/charged status.
