LION1CELL02

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

LION1CELL02A

This is an open-source hardware design, one of the modules from the MLAB labolatory system.

LION1CELL02 - Single-cell Li-Ion BMS power supply with I2C interface

LION1CELL02

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.

Features

  • 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

Connection

The module could communicate on the I2C or HDQ bus.
