Pacer Black 4 AWG Battery Cable - 50'

The Pacer Black 4 AWG Battery Cable — 50 feet — is purpose-built for marine electrical systems where reliability and amperage capacity cannot be compromised. Whether you're running a new dual-battery setup for extended cruising, upgrading an aging starter circuit, or installing an auxiliary charger system, this heavy-gauge cable handles the demands of saltwater and freshwater environments alike.

At 4 AWG, it delivers the current-carrying capacity needed for high-demand applications without voltage drop across longer runs—critical when every amp matters for reliable engine starts and equipment performance on the water. The 4 AWG copper core provides superior conductivity and corrosion resistance in harsh marine conditions, while the black PVC jacket shields the conductor from UV exposure, abrasion, and moisture intrusion. Pacer Group's marine-grade construction ensures the insulation remains flexible in cold water and holds up to the vibration, heat cycles, and salt spray that destroy lesser cable.

The 50-foot length eliminates mid-run splices on larger vessels, maintaining consistent impedance and eliminating weak connection points where corrosion initiates—a common failure point in battery systems. This cable meets marine industry standards for safety-critical DC power distribution. Boaters upgrading from undersized cable (8 or 6 AWG) will immediately notice improved starting torque and faster charging response—signs that adequate amperage is reaching the engine.
