The 3.7V Li-Ion battery charging module is a compact and efficient solution, designed to charge a single Li-Ion cell up to 4.2V using a linear charging circuit.
Power is supplied through a USB Type-C connector, compatible with any phone charger or power bank that provides 5V, making it extremely easy to integrate into DIY projects, portable devices, wireless headphones, or toys.
The module features two status LEDs: one lights up when the power source is connected, and the other indicates that battery charging is complete.
The default charging current is 600 mA, providing a balance between charging speed and cell safety. Thanks to its extremely small dimensions (10 x 7.5 x 5.2 mm) and standby current below 1µA, this module is ideal for low-power applications.
The module handles battery charging only and is not connected to the load or discharge voltage. Use it together with a BMS if discharge protection is desired.
Specifications:
Input voltage: 5V DC (via USB-C)
Charging voltage: 4.2V ±1%
Charging current: 600 mA
Supported battery: Li-Ion 3.7V (single cell)
Standby current: < 1µA
Operating temperature: -20 ~ 85°C
Dimensions: 10 x 7.5 x 5.2 mm

Usage:
Connect the 3.7V Li-Ion battery to the BAT+ and BAT- terminals, carefully observing polarity.
Power the module through the USB Type-C connector with a 5V source (phone charger, power bank, etc.).
The power LED will light up immediately, confirming that the source is properly connected.
The module will begin charging in constant current mode (600 mA) until the battery voltage reaches 4.2V.
After reaching 4.2V, the module automatically switches to constant voltage mode, gradually reducing the current until it falls below the preset threshold.
When charging is complete, the dedicated LED will light up, indicating that the battery is fully charged.
Disconnect the USB-C source after charging is complete if the module is not integrated into a system with automatic power management.
Warning!
Do not use this module for batteries with a nominal voltage of 3.2V (LiFePO4).
Do not exceed the 5V supply voltage on the USB-C connector.
Do not short-circuit the battery terminals.
Always check polarity before connecting.
