ACCEL Lightning Battery Cable allows your racecar to have the same amount of energy and power running thru your battery cables at half of the weight. The 4, 2, and 1/0 gage cable is half the weight of traditional battery cable. This allows you to lighten up your car or add weight were it will help the car handle better. The wire is available in 20 and 100 foot spools to re-wire one or several racecars.
