Tommy, thanks for the feedback. Are you saying that we shouldn’t let the battery pack stay plugged into the USB charger? That we can easily do.
However, I’m more interested in completely disconnecting the battery, then connecting power from the USB charger to the Piper’s board and the screen, similar to how I power my Raspberry Pi Zero when I’m developing on it. Is that feasible, or is the output from the battery somehow rectified to the Piper and screen that the USB charger cannot reproduce?
