Drake, I found the information available online at the Copper Development Association website to be valuable for DC applications:

Where do you find the specifications relating cross sectional area to amperage? Section 366.23 of the NEC allows 1000 A / sq. in. of cross sectional area of the conductor. Is that a good rule of thumb, or is there something more specific to battery busing?

Each battery has 2 terminals which will be about 2 1/2 inches away from the terminals they will be wired to. Standard battery jumpers would be ridiculous in this situation. Busbars would be clean and efficient. Concorde doesn't have a solution. Does anyone know of a source for busbars?
