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.
PowerBoost 500 Charger – Rechargeable 5V Lipo USB Boost @ 500mA+: PowerBoost 500C is the perfect power supply for your portable project! With a built-in battery charger circuit, you’ll be able to keep your project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects. (read more)
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.

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.
