Thanks cuppa. Ran it on mains last night so will see what happens today no charger with me for ark pack so hope today tops her up. No dick smith stove on today.

Thinking I might have to somehow add power from car to rear battery. Auto elec said my dual battery solenoid is rooted and not switching so may look at something that will do all three if such a beast exists. At least the solar is a top up.

Thanks
