We have 65 Freedom Rangers on order, with our chicken wagon built on a hay wagon almost complete. We will be using this wagon in one of our meadows. In the wagon I will have a closet with the electronics. I plan on having an RV power converter/distributions panel I will have indoor/outdoor RV style lighting coming off a 12v Deep cycle battery with a solar panel on the roof to keep it topped off. Im having trouble figuring out the best way to use the wagon with the battery to charge the fence. I already own a small 120v fence charger so I though about just running a 12/120 converter from the battery but I think that would use to much power? I do have a power source 120 power source about 250ft away through a bunch of trees to an outlet at our well but again, that may be to far or not? Maybe an outdoor rated extension cord? Any thoughts on this?
