I didn't see one battery in the cars I could get at , the picture on eBay is the circuit board that looks like a battery , seems the battery's go under the seat , when I say heavy I mean it's hard work for 2 people to lift up the rear with the gearbox and motor in but doable, but there's not much to get a good hold of and mud might of made it harder or perhaps I'm a whimp who knows , my opinion the roofs that have been jumped on are not creased so would pop out with a rubber hammer , one car has battered panels and a door bent open but rest are ok really for cars that have sat for years
