For now, I have something like a heat shrink over them. They are ment for going over anderson connectors. I plan to hot glue the ends, so water will not get in. Then I'm still not sure about the other wire connectors, on how to insure they are water proofed. I already sprayed the inside of the heatsink that goes over the controller, with 2 coats of rust paint. As only the outside was painted black, and the undearneath was exposed metal.
