I am not satisfied with using 8D starting batteries for my house needs, and I am switching to twelve 6-volt deep cycle golf cart batteries. Attached is a photo showing how my six 8Ds are connected.

The batteries are numbered 1-6 with all grounded at the negative terminal of battery 3. As to positives, arrow A shows the positive cable from battery 3 goes to the cutoff switch and apparently supplies the house needs. However, arrow B shows that an additional positive cable connected to battery 6 which seems to be connected directly to the inverter.

From a previous posting I saved an article by Smart Gauge Electronics which shows different ways to connect multiple batteries, and the worst way is to have all of the batteries connected and the exit cables connected to one battery.

I would appreciate comments regarding the correctness of my existing setup. Would it be better if I had different grounds for the two bands and not all connected together? Should positive from one bank go to the cutoff and the other to the inverter, and should all positives be connected as they are now?
