Hello. Very new to this. I bought a hobbyking drone kit and PXFmini with raspberry pi0 and almost have it figured out. I have a battery that is connected to Hobbyking power module v1.0 and that connects to PXFmini and powers the PXFmini and the raspberry PI0. My question is: when I plug the power cable directly into the raspberry PI0 from an external power source, will that charge the battery back through the PXFmini? Or do I need to plug a special charger into the power module v1.0?
