Shirbly 4 Gauge Battery Cable Kit – 5ft Red + 5ft Black 4 AWG Pure Copper Wire for Automotive, Solar, Generator

Overview

Meet the Shirbly 4 Gauge Battery Cable Kit, a practical dual-conductor solution designed for demanding DC connections. The kit arrives with two 5-foot runs, one vibrant red and one deep black, delivering 10 feet of high-current copper wiring. Built with pure copper and a robust EPDM insulation sheath, this cable is ready to meet the needs of automotive battery banks, solar installations, and generator circuits without compromising flexibility or reliability.

Material quality you can feel

The conductor is pure copper composed of 673 strands of 0.2 mm AS copper wire, chosen to balance conductivity with pliability. The insulation uses solvent-resistant EPDM rubber, paired with a polyolefin jacket for an extra layer of fire resistance. The result is a cable that remains soft and bendable, even when routed around tight engine bays or panel mounts, while standing up to tough conditions.
