Ultranautics Wiring Diagram. You can clearly see three sets of batteries each of which is 8 volts. First thank you for taking the time to comment.
What immediately jumped out at me is that you are using four 4 6 volt batteries following a diagram specific to parallel setup when you are most likely running a 12 volt system and need to follow the parallelseries diagram for your setup which is found on a different post. In the lower right corner you will see all the wiring running through the on. The batteries are numbered 1 thru 6 and connected in series positive to negative to create the needed 48v output.
