Grove - LTC2941 - Coulomb Counter 3.3V/5V

Description of product: Grove - LTC2941 - the-counter of coulombs - the meter of the rehargeable battery I2C level 

A module designed forreading the level of rechargeable single-chamber Li-Pol batteries, from 3.3 V to 5 V inreal-time. Thanks to this module, you will be able to count the number ofused amper-hours. When you use a fully charged rechargeable battery, you can check the status of the battery and its remaining percentage just like on the phone display. You can use this module to monitor the rechargeable battery charging process.
