Thanks everyone for your response. Jimmy, the fourth drawing in the article shows a very simple hookup arrangement for series and parallel connections. Steve, good idea to exit the ground and positive from different ends of the grouping. Forest, Costco sells International deep cycle golf cart batteries for only $90 with 232 amps. When you rebuild your rack, move the top tray up two inches to give a little more room in the bottom tray to hold the 11" batteries. I am replacing the caps on the new batteries with a low profile, gravity feed, automatic watering system. I am still curious about the dual positive cables, one out of the last (or first) battery in the line one one out of the middle battery in the line. Guess I will go with the way they are currently connected, except I will change the ground to the last battery and the positive to the first.
