Oh so adorable, this is the tiniest little lipo charger, so handy you
can keep it any project box! Its also easy to use. 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. 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 back, 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.
