Designed for Raspberry Pi series, compatible with Raspberry Pi 3 / 3B+ / 4B, etc.

I2C bus communication, monitoring the batteries voltage, current, power, and remaining capacity in real time

Multi battery protection circuits: over charge/discharge protection, over current protection, short circuit protection, and reverse protection, along with the equalizing charge feature, more safe and stable

Onboard 5V regulator, up to 5A continuous output current, more sufficient power source for Raspberry Pi

5V USB output, convenient for powering other boards; Batteries warning indicators, easy to check if the battery is connected correctly
