Datasheet

Solder the backpack on with the extra long header so that it can still plug into a breadboard,
or clip the long header leads short afterwards for a slim package. 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.
