From the project

Single-cell Li-Ion Battery management system with I2C interface

Integrated battery management solution for 18650 Li-ion batteries. It can measure remaining energy in the battery, perform a charging cycle from a USB-C power source, and protect batteries against overvoltage or overdraining conditions.

Charging, balancing, termination (temperature protected) Gas-gauging (temperature compensated) Over-voltage protection Over-current protection * Under-voltage is not protected - the module is constructed to power the device until battery death
