Hi and welcome to MHF.
As Jean says, the leisure batteries are usually joined together, but 80% is low anyway unless you are using power somewhere or not recharged, is the fridge sparking?
"There's no power for my waterproof" no idea what that means I'm afraid.
Did you turn on the new gas cylinder?
