Ancor Red 4/0 AWG Battery Cable - Sold By The Foot

The Ancor Red 4/0 AWG Battery Cable—sold by the foot—is the marine-grade electrical backbone every serious boater and angler needs for reliable power distribution. Whether you're running a high-demand trolling motor, installing a secondary battery bank, or upgrading your vessel's charging system, this tinned copper cable delivers the low-resistance performance required for safe, efficient power transfer in saltwater and freshwater environments. Battery cable sizing matters; undersized conductors cause voltage drop, dimmed lights, and weak engine cranking when you need it most.

This 4/0 AWG cable features ultra-flexible Type 3 stranding manufactured from tinned copper—a corrosion-resistant alloy that resists the galvanic attack of saltwater and the electrolysis that degrades standard copper in marine service. The tinned finish preserves conductivity and extends cable life through countless engine vibrations and thermal cycles. At 0.9 lbs per foot, this cable offers the gauge needed for high-current applications—engines, alternators, and bow-mounted electric motors—without excessive weight penalty. The flexible stranding reduces fatigue from vibration and allows for routing through tight spaces and sharp bends without kinking or breaking internal strands.

Professional installers and experienced anglers choose Ancor marine-grade cable for main battery runs, alternator leads, and high-amperage distribution systems on center consoles, offshore sportfishers, and utility boats. Purchase only the length you need—buy by the foot to eliminate waste and cut costs on smaller projects. Pair with tinned lugs, heat-shrink boots, and proper crimpers for code-compliant installations that pass survey and insurance requirements. Ancor's marine-grade designation means it meets ABYC standards and carries the durability reputation trusted across the boating industry.
