Ancor Battery Cable Assembly, 4 AWG (21mm²) Wire, 5/16" (7.93mm) Stud, Black - 18" (45.7cm)

The Ancor Battery Cable Assembly, 4 AWG (21mm²) Wire, 5/16" (7.93mm) Stud, Black – 18" (45.7cm) is purpose-built for reliable power distribution on your vessel, from center console fishing boats to cruising yachts. This marine-grade battery cable assembly handles the demanding electrical demands of starting systems, auxiliary loads, and charging circuits where corrosion resistance and conductivity are non-negotiable. Whether you're replacing a worn cable or upgrading your boat's electrical infrastructure, this assembly delivers the dependability that keeps you safely powered on the water.

Built with Ancor's premium UL1426 tinned copper cable, this 4 AWG assembly features fine-stranded conductors that maximize electrical conductivity while resisting the salt spray and moisture inherent to marine environments. The tinned copper construction prevents oxidation and corrosion—critical factors when operating in saltwater or brackish conditions. Pre-assembled with a 5/16" stud terminal, the 18-inch length accommodates typical battery-to-starter and battery-to-bus configurations on most recreational and commercial vessels without unnecessary slack or strain.

Anglers and boaters who log serious hours on the water recognize that battery cable failure is a silent killer—it compounds every electrical problem downstream. This assembly is compatible with standard marine battery terminals and charging systems rated for 4 AWG applications, making it suitable for single-engine outboards, twin-engine center consoles, and larger cruising platforms. Installation is straightforward: verify your existing stud diameter matches the 5/16" specification, secure connections with a torque wrench to prevent loosening, and ensure cable routing avoids sharp edges and moving parts.
