Lithium ion polymer (also known as 'lipo' or 'lipoly') batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 500mAh for a total of about 1.9 Wh.The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly. The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 3.0V. It will also protect against output shorts.
However, even with protection it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 500mA or less. Like most lipos, the battery does not have thermistors built in. This is why we suggest charging at 1C or even less - 100-500mA max in this case, which is how much you can get from a USB port. Polarity matches all Adafruit LiPoly/LiIon chargers and boards, other brands may have reverse polarity and can destroy your battery.

Additional safety notes:
Do not use a NiMH/NiCad/lead-acid charger!
Do not abuse these batteries
Do not short, bend, crush or puncture.
Never charge or use unattended.
Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring, or possibility of short circuits.
