Ever since I added my Eachine ProDVR to my EV800 googles, I have been getting a black screen randomly while flying. I think it may be an issue where the DVR is causing too much load (amp draw) on my lipo (I think the lipo was bad to start with…) causing it to sometimes drop in voltage; thus, effecting the LCD screen.
I plan to add a second lipo just for the DVR through a toggle switch. I’m not super good at EE, but would this wiring work or would it cause a floating ground because of the video and audio wires? I’m not sure, but I think the video and audio wires would flow current one-way only?
