How to run a Pi Zero (and other Pi’s) from a LiPo Including low battery @Raspberry_Pi #piday #raspberypi
Super useful hack from Daniel Bull posted on Google Plus, via raspberrypipod.
Including low battery automatic shutdown (to stop your SD card from getting corrupted), push button start, and automatic power supply off when the Pi is shutdown to stop your LiPo from going flat.
I’ve included full instructions on how to do this including circuit diagrams here:

Beware. The low power pin will go as high as the battery voltage. So with the used LIPO it will put 4.2Volts on your 3.3Volt input of your PI. I’ve done something similar with my Pi, but I’ve put a diode (1n4148) to lower the voltage and a resistor to lower the current between LOBat and GPIO.
