thinking of going away longer period off grid, have recently changed both batteries, we still have the old batteries which are in a reasonable condition.
we are taking a trailer on the back of the van , if we take old batteries as a back up power source what would be a suitable way to connect them into the van 12v system if needed.
obviously i wouldn't have thought using jump leads/
any other way apart from actually replacing batteries in the van
