Supermaxx89 - I generally wire my dean's similar to your diagram. The difference is on my setups, the wire that connects the rear of your batteries in your diagram is run from dean's to dean's. basically, it accomplishes the same thing. Positive from the controller to a positive Deans, Negative from the controller to the negative of another Dean's, and a wire connecting the two Dean's plugs together (positive to negative). No Harness required, and the batteries can be charged like normal.
