So I had a bit of fun creating a power source that allows me to go off grid and also allows me to be on grid if available. It inclueds the Epic PWRGate charger and power failover. A PWRcheck keeps tabs on the juice left in the battery and to power/charge it all a 30 amp fixed/adjustable power supply from PowerWerx or when the sun is up a 200 watt portable solar panel. The battery is a 76.5 AH Li-ion battery I built from scratch. The Go Box has my focus controller, a headless P.C., Powered USB hub and allows connectivity via ports in the rear of the box for USB, AC power and DC power for the mount and camera. I’ve attached a picture of the insides for your looking pleasure and will upload more photos once I get a chance to take them.
