Ancor Red 4 AWG Battery Cable - Sold By The Foot

The Ancor Red 4 AWG Battery Cable is the backbone of reliable marine electrical systems, whether you're wiring a center console, cruiser, or auxiliary power setup for extended time on the water. Sold by the foot, this heavy-gauge cable delivers the amperage capacity needed for engine cranking circuits, main battery feeds, and high-draw accessories without voltage drop or heat buildup. Any experienced boater knows that undersized or corroded battery cables create starting problems, navigation failures, and safety hazards—this product eliminates those risks.

Manufactured by Ancor with tinned copper stranding, the 4 AWG Red Battery Cable resists corrosion and electrolysis—critical advantages in saltwater and high-vibration environments where bare or galvanized copper fails quickly. The ultra-flexible Type 3 stranding flexes without cracking or fatiguing, essential when routing cable through engine compartments, along stringers, or through tight deck penetrations. The red insulation identifies positive circuits, preventing dangerous miswiring during installation or troubleshooting. Four-gauge wire carries substantial current (up to 100+ amps in short runs) while remaining flexible enough for real-world boat installations.

Anglers and boaters upgrading charging systems, adding auxiliary battery banks, or replacing corroded factory cables rely on this specification for dependable performance. The per-foot purchase option lets you buy exactly the length needed—typical runs from battery to starter solenoid, main bus bar, or remote switch may require 6 to 20 feet depending on hull layout. Pair this with quality marine battery terminals, fuses rated for 4 AWG, and proper grounding practices to build a system that starts reliably and powers electronics through full offshore days. Compatible with all standard 4 AWG marine terminal lugs and battery post adapters.
