WindyNation's battery cables are manufactured using our Power-Flex Welding cable, which is a highly flexible industrial grade electrical copper cable. WindyNation's battery cables are excellent for battery bank wiring, inverter cables, grounding cables, RV & car wiring applications, golf cart wiring, and any other application where a highly flexible pure copper conductor is required. Our battery cables are available with pre-attached cable lugs with 5/16" or 3/8" diameter mounting holes. Polyolefin heat shrink tubing is applied at the cable lug attachment point to form a protective seal.
