I built my cables and they have SB connectors in between that I can unplug and add an extension in, also run the NAPA connectors. I can pull in front of a vehicle and run my cables from my batteries to the back of my pickup and hook onto the other vehicles batteries and start them. No turning around on a highway or were ever to jump them. Made from heavy gauge welding cable.
