new scamp lovers here— we are uneducated in the rv battery department. All I know is my jeep has to be jumped every time now after leaving the scamp plugged into the tow vehicle overnight. An accident that I'm seeing now is gonna cost me! Took the jeep on a few hour drive (no scamp) to see if i could get it charged up again, but no dice. It's my understanding that the four prong that came on the jeep is not the right thing to charge a deep cycle marine rv battery as came with our scamp (which had been sitting dead for a while) as we drive. With the o'reilly adapter to seven prong it works great for making the lights and turn signals work on the road, but this set up will not charge the trailer battery as we drive right? Also Inside the scamp is a fancy 45AMP converter that has ability to do whats called a three cycle charge if my research is right, but is this for shore power charging only? or does it also have somethin to do with charging while driving?
If anyone could be so kind as to explain the basics to me and/or recommend a good new battery for the scamp I would greatly appreciate it! We want to do a good bit of dry camping, are interested in buying a new battery under 400$ for the scamp and also down the line do a solar panel when we get a little cashflow, so we'd like a battery that would be good for solar + dry camping for a couple nights with the furnace going! Any advice appreciated, many of the other answers regarding wiring have been helpful to read but more complex than i'm able to follow
