Oh so handy, this little lipo charger is so small and easy to use you
can keep it on your desk or mount it easily into any project! Simply
plug it via any MicroUSB cable into a 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. Seriously, it could not get more easy.

Charging is performed in three stages: first a preconditioning
charge, then a constant-current fast charge and finally a
constant-voltage trickle charge to keep the battery topped-up. The
charge current is 100mA by default, so it will work with any size
battery and USB port. If you want you can easily change it over to
500mA mode by soldering closed the jumper on the front, for when
you'll only be charging batteries with 500mAh size or larger.

For use with Adafruit LiPoly/LiIon batteries only! Other batteries
may have different voltage, chemistry, polarity or pinout.
