Spartan Power 4/0 AWG welding cable
The Spartan Power Single Red 4/0 AWG cable is a four‑foot heavy‑duty welding lead built for high‑current battery and inverter connections. It suits installers wiring RV, marine, solar or fleet‑truck systems that demand pure‑copper conductors and reliable crimped terminations.
4/0 AWG capacity and 1000 V rating
At 4/0 AWG the conductor comfortably handles the heavy starter and inverter loads found in large mobile and off‑grid installations. The UL 1232, 1284, 1338, 1346 and 10269 approvals and 1000 V rating provide headroom for most DC distribution tasks, while the VW‑1 and moisture‑resistant jacket protects against abrasion and environmental exposure.
Upgrade from smaller gauge battery leads
Builders replacing 4 AWG, 2 AWG or 1/0 AWG cables gain lower voltage drop and cooler operation under sustained high‑current draw. The lifetime crimp warranty and adhesive‑lined heat‑shrink terminals make the step up worthwhile when existing leads run hot or show terminal fatigue.

Questions about this item
Will the 4/0 AWG cable fit the 3/8-inch ring terminals on my existing battery posts?
The cable assemblies use either 5/16-inch or 3/8-inch ring terminals depending on cable size, so the 4/0 AWG version should match standard 3/8-inch battery posts.
How can I verify the crimp quality after installing the cable?
The Lifetime Crimp Warranty covers any crimp issue for free repair, giving you a direct way to confirm workmanship if a connection ever feels loose or shows heat.
Does the 4-foot length come with heat-shrink already applied or do I need to buy adhesive-lined tubing separately?
The cables arrive cut to length and ready to use with adhesive-lined irradiated polyolefin heat shrink already installed on the terminations.
