Re: Question about six volt GC batteries
Adding bus bars does not add to the complication - it keeps the batteries neater and easier to check fluids as well as cleaning of the tops. There is nothing messier than a bank of batteries with wires going every which way from the posts. As far as wingnuts go, they can't be wrench tightened to the proper torque and this can lead to loose connections and the problems that brings. I think many with small outboard boats like the wing nuts but they have no place on a proper marine battery installation.
I recently installed a bank of 8 golf carts and a large inverter on a 48' boat. Positive from one end of the bank and negative from the other end to draw the bank down evenly. The only extra connection was a temp sensor which went to a battery in the middle. The main posts had only one connection each which went to buses. A neat installation that is simple to service and trouble shoot if necessary.
Trojan batteries have studs - and you only need one per battery. The standard stud works very well.
