These are the same cables that I make in my big three kits, but here you can order each cable individually. This allows you to get more custom lengths for your own wiring needs. You can make your own big three or big four kits this way.  

I use EB Flex copper welding cable. Extremely flexible, copper 30g strands, made in USA, rubber jacket, covered in Techflex brand flex loom, and heat shrunk with my adhesive lined heat shrink.

Ring terminals are optional on both ends (if you want only one end crimped then please specify when ordering and I will include a wire ferrule instead of ring for the second end).
Ring terminals are tinned copper with a large contact patch for best current transfer. 5/16" opening on the ring. You can drill these out with a step bit if you need larger openings. If you need a smaller 1/4" ring opening then please specify in the special requests.
