I am connecting my 2 batteries in parallel straight to the bus bars instead of to eachother via + to + and - to -. My question is. I have a battery shutoff attached to the bus bar as seen in picture below. Do i need to attach the two + wires from the batteries to the same node as the shutoff wire is attached to on the buss bar or can I attach it to any of the positive nodes on the busbar? Also if I attach it to the open node on the busbar can i attached both of the positive wires to the same node?
