Wiring batteries

[Lifted Monte Carlo]

It was said to hook batt's up in both series and parallel.  My question is this, what would you then recommend for connecting the batt's?  Such as cables, metal rods, straps, etc....

I feel copper strips are the best for best flow.

If copper tubing (metal rods) are at 100% copper, then that is a good choice too.  Thing is, bare metal for a positive is asking for trouble.  But would be Ok on the ground side. You could always cover up the bare metal. I used to use mtal strips for the solinoids.

Next would be thick cables, battery cables with crimped ends might have some resistance. The thicker the better.

Ground straps in my opinion are questionable, but if made of silver plated copper, then that's good.
