Today I finished replacing the single 12V battery on our 2018 White Hawk 26RK with two 6V golf cart batteries. The factory cables were too short to reach the batteries, so I used a dual PowerPost cable connector to connect the factory cables, and the two cables I built to reach the batteries. I did not want to mess with the factory cable connectors. That way we can go back to factory settings and a single battery if we ever decide to upgrade the trailer, without have to cut and replace cable terminals. While I was at it, I also added a battery disconnect to the battery box. I "borrowed" part of this idea from an installation I saw at another forum.
