There are two different ways that you can attach the four 12 volt batteries to your 1983 Blue Bird Wanderlodge. You can attach them in series or parallel. Attaching the batteries in series will increase your power output. Attaching the batteries in parallel will keep power output the same but increase the capacity. The best way to wire them is all going to depend on how you use them. However, I recommend wiring them in parallel so you do not end up with a 48 volt system that would be difficult to run.

I have attached a photo that shows how each battery will need to be wired in order to make them series or parallel.
