Power Supply for Raspberry Pi 3, Raspberry Pi Pro V1.1 UPS HAT I2C Lithium Battery Expansion Board

Description:

This is a power expansion Board especially designed for Raspberry Pi, which enables to
use the Raspberry Pi with a moveable power source. It's more convenient to use external
3.7V Lithium battery or 3.7V 18650 Lithium battery;

Specification:

• Supports I2C Output with Capacity & Voltage Reading Function;

• Two power supply modes: GPIO power output and USB power out;

• Support Raspberry pi or Android & Apple Phone or Pad or other electronic device charging;

• Supports charging while discharging,(it's stable output, the maximum output current can up
  

  to 1.8A while charging, but the chip heat will become larger.
  

  Maybe you can place a external heatsilk on clip.)

• With 4 LED power indicator;

• Standard dimension of Raspberry Pi HAT;

• Removable battery, The external lithium battery requirements: 3.7V lithium battery;

• Built-in power path management, perfect support charging While discharging.

• Intelligent 3-stage charging (trickle, constant current, constant voltage), it can effectively extend the battery life.

• Maximum discharge current: 2A, Maximum charge current: 1.8A;

• Output protection: overcurrent, short circuit, undervoltage protection;

• Input protection: overvoltage, overcharge, undervoltage protection
