XS Power has a reputation of manufacturing the highest quality and highest performance batteries on the market, and now you can get that same quality and performance throughout your entire electrical system with the new XS Power XS Flex and XP Flex power cable. The XS Flex line of power cable is XS Power's flagship power cable. It is available in Blue (XSFLEX0BL-50) and Clear (XSFLEX0CL-50) and in both 50' spools or in 1' increments. The XS Flex Cable is 100% Pure Oxygen Free Tinned Copper Cable with a massive 4,704 strand count. Just like everything else XS Power does the XS Flex Cable exceeds the industry CEA-2015 cabling standards and is True AWG cable. The high strand count and soft touch cable jacket allows the wire to be super flexible and easy to use in any installation.


XS Power's Big3XS kit includes heavy-duty 1/0-gauge oxygen-free copper cables that replace your vehicle's battery ground-to-chassis wire, the chassis-to-engine block wire, and the alternator charge output wire. Another bonus is that the ring terminals are already crimped to the wires, so you won't have to replace the stock grounds unless you want to improve them or double up.
