Raspberry Pi enthusiasts but would like to be able to projects using a battery, may be interested in a new Raspberry Pi HAT which has been created by Mark Chin based in Canada in the form of the Pi18650 HAT
The Pi18650 has been created to provide a HAT which plugs into the 40 pin connector on the Raspberry Pi and allows you to operate your Raspberry Pi mini PC without the need for a power cable.
The Raspberry Pi battery HAT is capable of supporting various capacity 18650 Lithium Ion batteries. Watch the video below to learn more.
The Pi18650 holds a single cell lithium Ion 18650 form factor battery which should have an integrated battery protection circuit. 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. It also includes a charging IC which can charge up to 1A from the USB Micro connector and has a battery monitoring IC which communicates to the Pi via I2C. We have coded a Python script using I2C SMBUS for you to read the battery status. Charging LEDs show the status of the charging process. The Pi18650 can also be used with other development and SBC boards. Any DC power adaptor up to 6V max can be used with the charger.
