Alex the Giant, Ell C Introduction
The SparkFun LiPo Charger Plus is the souped-up power option in the SparkFun line of single-cell lithium polymer (LiPo) battery chargers. With this iteration, we've changed the input charge connector to USB-C and provided charge rate selection as well as optional thermal protection. Charge, power, and done LEDs clearly indicate the status of your charging process.
