SparkFun – USB LiPoly Charger – Single Cell

SparkFun: PRT-10161

Description: If you need to charge LiPo batteries, this simple charger will do just that, and do it fast! The USB LiPo Charger is a basic charging circuit that allows you to charge 3.7V LiPo cells at a rate of 500mA or 100mA. 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, selectable solder jumper for 500mA or 100mA charging current, external LED footprint, USB input, mounting holes, and various holes for your own connectors. We include a single JST-tpye connector which connects directly to our LiPo batteries. The connector comes unsoldered, so you can use it or not.

There is also a ‘SYS OUT’ which allows you to connect the charging circuit directly to your project so you don’t need to disconnect the charger each time you want to use it.
