Pacer Green 4 AWG Battery Cable - 50'

The Pacer Green 4 AWG Battery Cable – 50' is purpose-built for marine electrical systems where reliable power distribution between battery banks, inverters, and engine starters is non-negotiable. Whether you're outfitting a center console, sport fisher, or expedition cruiser, this heavy-gauge cable ensures the low-voltage, high-amperage circuits that power modern marine electronics and propulsion systems stay clean and fault-free. At 50 feet, you have the run length needed for most single-engine or twin-engine installations without mid-span connections that introduce voltage drop and corrosion points.

Four-gauge (4 AWG) copper conductor delivers the cross-sectional area required to handle sustained 100+ ampere loads with minimal resistance loss—critical when you're firing a 200-horse outboard or running a 3,000-watt inverter through the same cable run. The Pacer Green jacket is UV and oil-resistant tinned copper construction, designed to withstand the salt spray, fuel splash, and temperature cycling endemic to marine engine compartments. Unlike automotive-grade cable, marine-rated products like this meet ABYC (American Boat and Yacht Council) standards for insulation thickness and flame propagation, ensuring compliance with most insurance and coast guard inspection requirements.

Boat electricians and serious DIY installers choose 4 AWG when running main battery feeds, emergency generator circuits, or auxiliary DC systems on vessels 25 feet and larger. The 50-foot length accommodates transom-mounted batteries, engine room remotely mounted alternator isolators, and helm-to-engine-block ground runs without splice joints. Pair this cable with marine-grade battery terminals, shrink-wrap adhesive-lined tubing, and stainless hardware to complete a system that will outlast the boat's original owner. This product is not recommended for engine starting cables under 3 feet—use dedicated starter cable for those runs—but it excels as a trunk line for distributed power architecture.
