PCB Inside battery pack? #3
Description
It seems like you are using a 4S 14.8v lipo battery, but the wiring doc states there is a PCB inside the battery pack as well. Can you share more details on this? Is it required?
I also noticed you are providing the panels 4V instead of 5V. Is there a reason for this?
(I am also hoping for 3D models of the frame, but not as big deal as the tech details)
