I'm planning to build a robot similar to one described here. The pi and the controller are going to be powered from powerbank. However, as big fan of live coding I am (there's gonna be some LISP involved), I can't stand the fact that for developing I will probably have to turn it off, plug powerbank off, plug mains in, start (powerbank can't serve as source while charging).
What are my options here to avoid needless restarts?
Should I just try and plug the powerbank to the 5V pin (as described here? This would free the microUSB, but it seems to be a bit dangerous (no idea how stable powerbank current is)
Backfeed with powered HUB somehow (as much as dangerous as previous option)?
Connect powerbank to the mini driver and then mini driver 5V out to raspberry pi 5V pin - this could be safer because the mini driver would secure it? (no idea if it would)
