The battery on a camper (or trailer) has nothing to do with vehicle brakes. It's strictly for use by the camper/trailer.
It supplies power to all the 12volt systems in the camper- but if you have nothing powered by 12 volt, get rid of it.
That's some BAD advice right there! If the camper becomes detached from the tow vehicle it loses the 7-pin connection and the power it gets from the tow vehicle. The breakasway switch will activate the brakes BUT only if there is a battery to power the brakes. This is REQUIRED BY LAW. You will see even utility trailers, if they are large enough to need brakes, they will have a battery even if it's a 12v dry cell.
