This small charger will allow you to recharge your batteries polymer Lithium Ion 3, 7V/4, 2V using a simple USB port. The batteries are connected on the Adafruit Micro Lipo with a conecteur JST 2 points. Two LEDS are present, a red that illuminates during the load and a green when the charge is complete, in short, it's easy to use.

The load is done in 3 steps:
