I want to pull ten amps out of a little 35 ah battery for one hour and then fully recharge. Will this heavy draw destroy the battery? I know it is a small battery.
OK, if it's just a camper shell, we are talking about a drastically smaller space than even most truck campers. 250w might do the trick if it's just a little chilly.
As others have mentioned, a 12v heater probably makes more sense but still need a bigger battery. That or some higher wattage 12v bulbs as most of the energy turns to heat anyway.
