The Pi18650 DUAL BATTERY HAT holds two single cell lithium Ion 18650 form factor batteries which should have integrated battery protection circuits. The boost circuit maintains the voltage to the Pi at 5.1V for battery voltages of 3.7V to 4.2V. The jumper allows you to disable power to the Pi and Isolate the battery circuit or start the Pi. This jumper can be used with an external relay providing automatic control from circuit or system. It also includes two charging IC's which can charge up to 1A from the USB Micro connector and has two battery monitoring IC's which communicates to the Pi via I2C. We have coded a Python script using I2C SMBUS for you to read the battery status along with a shutdown script for low battery voltage. Charging LEDs show the status of the charging process. The Pi18650 DUAL BATTERY HAT can also be used with other development and SBC boards. Any DC power supply, adaptor or solar panel up to 18V max can be used with the charger. Use a good quality USB Micro cable as we found the flat style thinner cables did not work well with the charger and current was limited. The thicker round USB Micro cables work well.
