Hello. I recently installed the Windcamp battery in my my 817 and have a quick question. I know to charge the Windcamp from the new charging port on the new hatch but Can I use the rear power plug on my my 817 as another power source with the Windcamp hatch in the off position? My goal is to use the full size battery or power supply as my main source of power and the Windcamp as a secondary power source if needed. I assume this is what most people do, I just didn't want to do any damage... Sorry for the dumb question.
