Ancor Red 4 AWG Battery Cable - 25'

The Ancor Red 4 AWG Battery Cable – 25' is a marine-grade tinned copper conductor designed to deliver reliable power distribution on boats, offshore vessels, and RVs. Built from Type 3 ultra-flexible stranding and wrapped in Ancor's proprietary vinyl insulation, this 25-foot battery cable resists the corrosive environment of saltwater boating while maintaining its flexibility even in extreme cold. The 600-volt rating and resistance to battery acid, gasoline, oil, and UV radiation make it the standard choice for serious anglers and vessel operators who demand long-term reliability below deck.

The 4 AWG gauge supplies substantial current capacity for high-draw applications—battery banks, alternators, inverters, and main power distribution on mid-to-large vessels. Tinned copper stranding prevents electrolysis and corrosion that degrades performance in saltwater environments, a critical factor for anyone running extended offshore trips or keeping a boat in service year-round. The cable's exceptional flexibility resists fatigue from vibration and repeated flexing during vessel operation, extending service life far beyond standard marine cable. At 4.7 lbs per 25-foot spool, installation is manageable without requiring heavy equipment.

This cable is essential for weekend fishermen upgrading their electrical systems and for professional charter boats, commercial vessels, and serious cruisers who rely on stable power delivery for navigation, fish-finding electronics, and safety equipment. Whether you're running a new battery bank, replacing deteriorated cable in a legacy system, or building out auxiliary power on a larger vessel, the Ancor 4 AWG marine-grade specification ensures performance in saltwater conditions where standard automotive or general-purpose cable fails. The 25-foot length covers most main power runs without requiring additional splicing.
