Adafruit Micro Lipo - USB LiIon/LiPoly charger - v2

This little lipo charger is easy to use just simply plug in the gold plated contacts into any USB port and a 3.7V/4.2V lithium polymer or lithium ion rechargeable battery into the JST plug on the other end. There are two LEDs - one red and one green. While charging, the red LED is lit. When the battery is fully charged and ready for use, the green LED turns on.
