To use the 6-volt battery you need to purchase 2 batteries and connect them in series which is positive to positive and negative - to negative - and then run the positive and negative to the coach. In parallel the voltage stays the same and in series it is doubled. The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity. So if you are wiring two 6V batteries in series you will simply connect the positive terminal of one battery to the negative terminal of the other.
