Shirbly 4 Gauge Battery Cable – 20ft Red & 20ft Black, 4 AWG Pure Copper OFC Wire

Overview

Meet Shirbly’s 4 Gauge Battery Cable, a versatile power lead designed for demanding environments. Built around a pure copper core and protected by a robust EPDM insulation, this two-color set (red and black) provides a clear, durable path for DC power from automotive batteries to solar arrays and generators.

Key materials and ratings

• Pure Copper Wire Material: Fully annealed OFC core with 673 strands of 0.2 mm copper wire delivers low resistance and flexible handling.
• Heavy Duty Performance: Rated up to 600 volts and engineered to perform across a broad temperature range: -58°F to +221°F (-50°C to +105°C).
• EPDM Insulation Sheath: Heat, wear, tear, moisture and oil resistance with a soft, bendable profile for easy routing in tight spaces.
• Wide Applications: An excellent option for automotive leads, solar systems, and generators, especially in DC circuits where copper is preferred.

Performance and durability you can count on

The two-conductor design paired with a high-grade copper core enables efficient power transfer and reliable starts in vehicles and off-grid setups. The color-coded red and black conductors help keep polarity correct, supporting neat, safe installations.

• Excellent heat resistance and stability across a wide range of conditions.
• Soft insulation aids bending and routing in engine bays, panels, or exposed harnesses.
• Clear polarity with two-color design reduces installation errors.

Real-world use cases

Envision replacing a worn lead on a truck battery, wiring a portable storage system for a solar array, or powering a remote generator. This kit’s dual-length design provides flexibility for different layouts and setups, while the copper core aims to minimize losses in demanding DC paths.
