Charger 2 click is a LiPo/Li-Ion battery charger with the additional monitoring IC onboard. This Click board™ as a whole, offers unpreceded battery charging and monitoring solution for 3.7V LiPo/Li-Ion batteries, with the capacity measurement/gas gauge function, for up to 7000 mAh. It provides measurement data via the I2C interface and two signaling LEDs on the Click board™ itself. It features two dedicated ICs - one for charging the battery and one for monitoring its status. The charging function is performed by the STBC08, a standalone linear battery charger IC, while the monitoring of the critical battery parameters is done by the STC3100, a battery monitor IC with Coulomb counter/gas gauge.
