Description: If you need to charge LiPo batteries, this simple charger will do just that. 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 mini-USB connector. However, we do not recommend this charger with a 110mAh battery.
Note: This version uses a mini-USB cable. We also have this charger with a micro-USB connection as well.

The device doesn’t have load sharing, meaning that it’s not designed to be used in an embedded system, i.e., charging the battery while also powering the battery-powered circuit. If your load circuit consumes too much current (not tested, but guessing on the order of a milliamp), the charge may never “finish”. The data sheet shows a simple circuit modification to allow this. The device works as designed, just keep that in mind.
