Re: House Battery on Trailer?
My race car trailer, (An aluminum Featherlite), has electric brakes which require an electric source to actuate the brakes in the event that the trailer becomes separated from the towing vehicle. So, it has a battery on the trailer which is charged by a dedicated prong on the 7-prong plug. I just plug it in and go, and the trailer battery charges automatically. Not sure why it doesn't overcharge, but it has worked perfectly for 5 or 6 years, even if I don't use it for a few months.
