iGreely 4 AWG Battery Cable Pair 2FT (Red & Black) — Pure Copper, 5/16" Ring Lugs, Ultra-Flexible

iGreely 4 AWG battery cable is a flexible, heavy‑duty pure copper power lead with pre‑crimped 5/16" ring terminals, sold as a 2‑foot red and black pair for automotive, marine, RV and solar use.

Built from fine‑strand pure copper and covered in durable EPDM insulation, these 4 gauge leads are engineered for demanding environments. Each cable is rated to 600V and tested to operate across a wide temperature range, and the closed‑end 5/16" lugs simplify installation while protecting the conductor from corrosion and contaminants.

How does this cable handle high‑current and repeated flexing?

The conductor is made from 673 strands of 0.2mm AS pure copper, giving the cable both excellent conductivity and exceptional flexibility. That fine stranding reduces work‑hardening and fatigue when routed through tight bends or around battery trays.

• 673-strand pure copper core for improved current flow
• Ultra-flexible design for tight routing and vibration resistance
• Pre-crimped lugs to maintain a consistent electrical connection

What protection do the lugs and jacket provide outdoors?

The 5/16" ring terminals feature a closed‑end design that shields the conductor from moisture, acid and solvents commonly found in automotive and marine settings. The EPDM rubber jacket is abrasion‑resistant and rated for both high and low temperatures to keep insulation intact under stress.

• Closed-end copper lugs guard against corrosion and contaminants
• EPDM jacket is waterproof, flame‑retardant and abrasion resistant
• Temperature range −67°F to +221°F (−55°C to +105°C)

Which installations and projects is this 4 AWG cable suited for?

This pair works well wherever a short, high‑current connection is required — battery to starter, inverter to battery bank, or short runs in solar and RV power systems. The 2‑foot length is convenient for tidy battery connections and small‑space wiring layouts.

• Automotive battery hookups, starters and grounds
• Marine and RV battery banks and inverter connections
• Solar arrays, golf carts, distribution panels and DIY wiring

Who is this for? Electricians, mechanics, boat owners and DIYers who need a short, robust 4 AWG connection will appreciate iGreely's balance of flexibility, corrosion protection and easy installation. If you require longer runs or different lug sizes, iGreely offers other gauges and configurations to match system requirements. Purchase with confidence knowing the cable is designed for demanding environments and backed by customer support for replacements or refunds.
