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 500mA 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 micro-USB connector. Four small mounting holes allows this charger to be easily embedded into a project.
Project 1. Light of Earth - A BMI160 gyroscope accelerometer based 3D Printing LampA light can be turned on by knocking on the table.
