The SparkFun Battery Babysitter is an all in one single cell Lithium Polymer LiPo battery manager.

It s half battery charger, half battery monitor, and all you ll ever need to keep your battery powered project running safely and extensively. The Battery Babysitter features a pair of Texas Instruments LiPo management ICs: a BQ24075 battery charger and a BQ27441 G1A fuel gauge.

The charger supports adjustable charge rates of up to 1.5A, as well as USB compliant 100mA and 500mA options. It also features power path management, guaranteeing power to your project even if the battery has died.

The self calibrating, I2C based BQ27441 G1A measures your battery s voltage to estimate its charge percentage and remaining capacity.
