Product description
Protected Li-ion / Li-Po charger module for charging a single lithium-ion or lithium-polymer cell (3.7 V). The module uses CC/CV charging (constant current/constant voltage). Power can be supplied via USB-C or VIN (4.5–5.5 V). A 2-pin JST connector or solder pads are provided for battery connection. The module features built-in protection against overcharging, over-discharge, and short circuits. Two status LEDs indicate the charging status. Suitable for battery-powered projects using Arduino, ESP32, Raspberry Pi Pico, and other microcontrollers.
The module can supply loads up to 1 A and features separate outputs for the load, allowing the battery to be used while it is charging. Four mounting holes simplify installation in both prototypes and finished designs. Please note that the module does not provide reverse polarity protection, so the battery must be connected with the correct polarity. Supplied with: Pin header (not pre-soldered).
