I plan on connecting 4 kinetik hc1800 together with 2in x .25in copper or aluminum bar from the hardware store. Would like to do bus bars with built in inputs but due to the placement of the batteries, the bar may require some flex due to the curvature of the boats hull. Hence the quarter inch thin 2 inch wide bar. Anyways I would like to have bat terminals with 6 1/0 gauge inputs and one 8 gauge input and obviously a hole for fasting to the battery with the bus bar between the battery and the terminal. I want the terminals to be long ways so all of the terminal will rest on the bus bar for maximum contact and all of my wires will come off the same direction. Need one for pos of for neg. What would something like this cost? Alum and copper price please. Also I want the wires to connect from the outter edge of the battery, not lie over top of the batteries. Do you see what Im trying to describe?
