I have an Adafruit Micro Lipo Charger and a small 500mAh LiPo battery and have been just using it to charge the battery so far.
Is it possible to connect the charger directly to a Raspberry Pi and have the pi powered by the usb while plugged in (and charging the battery) but then using the battery power whilst not plugged in? Or is that asking too much? ;)
All the best,
