I would go with 2 6-volt golf cart batteries, they can handle being drained of power, normal car batteries can’t.

Also I would keep any lead acid battery outside as they give off explosive gas when charged. If you are going to put them inside use gel-cells or AGM batteries. They don’t give off gas. But they really need a charge controller as they can’t handle being over charged.
