Bigger the better.
I make my own from #1 welding cable and swage/solder/shrink copper ends to them.
Ground should be same size, you can't have too many.
I use copper antisieze on all the connections.

If you're of a mind to build your own, use welding cable in the appropriate size (I use #2). It has better insulation that takes higher temps and has many more individual wires which carry more amperage.

You should not solder battery cable terminals. Battery cables put a decent amount of leverage on the terminal, which can break the joint. Crimping the cable instead allows it to flex; and this is how store-bought cables are built. The proper way to build battery cables is with a crimper designed just for that purpose.
