I want to put a power inverter in my car trailer just to run some 110v flourescent lights. With the 7 pin plugs there is supposed to be a wire that charges a battery like on a camper. My trailer has a small battery to run the break-away brake so I'm assuming that stays charged when it is plugged into a running tow vehicle. My question is, can I put a battery in the trailer to run the inverter and have the battery charge when I am towing just like a camper? Anybody ever try this? I'm assuming it can be done and probably isn't all that hard to do. Thanks!

We used to do that with our old trailer before we got a generator.We wired from the battery on the tow rig to a seperate plugin on the rear bumper then wired from the battery in the trailer to a plug on the tounge of the trailer.That kept the battery up to run the winch and toolbox lights.It's a good idea to unplug it while you are at the track if you use a lot of lights though because it can drain your tow rigs battery "voice of experience"
