Note: Do not include 18650 batteries, Please Buy alone.

   Features

• Adapting various interfaces via cables, easy to integrate into mobile robots or industrial control equipment
• I2C bus communication, monitoring the batteries voltage, current, power 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 and Jetson Nano
• Batteries warning indicators, easy to check if the battery is connected correctly
• Comes with online development resources and manual

   Specifications
