Lithium Battery Charger V1.0

If you need to charge LiPo batteries, this simple charger will do just that, and do it fast! The Lithium Battery Charger can charge 3.7V LiPo battery at a rate of 500 mA per hour. It is designed to charge single-cell Li-Ion or Li-Polymer batteries. Check the datasheet below to see if it will work with your battery.

The board incorporates a charging circuit, status LED, connector for your battery (JST-type used in the batteries we carry), and a Type-C USB connector. Two small mounting holes allows this charger to be easily embedded into a project.

V1.0 update content:

1. PCB silk screen printing is upgraded from V0.2 to V1.0

2. Add current pad selection on the back of the PCB and select the appropriate charging current by shorting the pad (100mA, default 500mA, 700mA, 1000mA)

3. The charging interface Micro usb port is updated to Type-c port, which is more convenient to use.

4. Add two output interface terminals, 3.3V and 5V, which can be used to power other devices.

5. Added reverse connection protection pad function, mainly used when the battery is completely discharged, the charging indicator light and the full power indicator light will light up, and normal charging cannot be performed. After the reverse connection protection pad is welded, normal charging can be performed, but the module will lose the reverse connection protection; after the short-circuit protection pad is disconnected, the reverse connection protection function can be restored.
