My camera with the lithium batteries just went dead tonight on day 90. It lasted longer than any of my cuddeback solar cams by twice as much. You’re running 6 volts to your G series? I was told they were a 9 volt camera and that’s what I’ve been using without any issue but 4 of the 1.5 volt D cell batteries is obviously 6 volts. Guess I should step the voltage down to 6 on my G series before I smoke the camera.
