Lithium ion polymer (also known as 'lipo' or 'lipoly') batteries are thin, light and powerful. This battery is ideally used for portability of your prototype With Charging protection circuit The battery includes following electrical characteristics. Output voltage – 3.7V Capacity – 3000mA Internal resistance 80 mOhm Charging constant – 250mA (0.5C) Dimensions Cable length – 10 mm Connector JST-PH – 2P Do not over charge or fully discharge. 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 this 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 batteries we sell do not have thermistors built in. This is why we suggest charging at 1/2C or even less - 500mA max in this case which is how much you can get from a USB port.
