If you look on Google, there are pictures that show how to properly
connect battery banks.

You can just make parallel cable wires with crimp on terminals, but if
you want to add another battery, you then have to modify the cable
assembly to accommodate the new battery. The bus bar or terminal strip
works quicker and multiple bus bars can be added without too much trouble.
