Ancor Red 4 AWG Battery Cable Spool, 100-Foot

The Ancor Red 4 AWG Battery Cable is a 100-foot spool with Type 3 ultra-flexible construction, rated 600V.

Four gauge is the size most boats use for windlass feeds, thruster circuits and sub-panel supplies. A hundred feet is enough for both the positive and return on a typical foredeck circuit, or for two or three shorter runs, and that makes it the common length to stock.

Tinned copper stranding protects against corrosion and electrolysis where salt and moisture reach the conductor. That protection matters most at the ends, where the insulation is cut and bare copper would otherwise wick moisture up inside the cable.

Ultra-flexible Type 3 construction improves routing through battery compartments and machinery spaces while resisting vibration fatigue. Premium vinyl insulation stays flexible in extreme cold and resists salt water, battery acid, oil, gasoline and UV, rated 105°C dry and 75°C wet. Explore more battery cable.
