Shirbly 1/0 AWG Flexible Battery Cable Red + Black 1.5ft Pair — OFC Copper, Pre-crimped 3/8" Terminals

Shirbly 1/0 AWG flexible battery cables are a pair of 1.5-foot, oxygen-free pure copper power leads finished with pre-crimped 3/8" (M10) round-hole terminals, built for high-current battery, inverter, solar and welding connections.

These cables combine fully annealed OFC (oxygen-free copper) conductors, solvent-resistant EPDM insulation and tin-plated copper lugs to deliver durable, low-resistance connections where reliable power transfer matters. The set includes one red and one black 1.5 ft lead, both fitted with crimped closed-end lugs and supplied with 3:1 dual-wall adhesive heat-shrink tubing sized for 3/8" studs.

How does this cable handle high current and heat?

The 1/0 AWG conductor is made from 1703 strands of 0.2 mm AS copper wire and is fully annealed to maximize flexibility and conductivity, minimizing voltage drop under load. Insulation and lug materials are chosen to endure wide temperature ranges and resist common solvents.

• Rated for up to 600 volts for many DC and low-voltage DC systems.
• Works between -58°F to +221°F (-50°C to +105°C) for hot or cold environments.
• Tin-plated copper lugs resist corrosion in outdoor or marine use.

What makes installation quick and secure?

Each cable arrives with both ends factory-crimped to 3/8" (M10) round-hole terminals so you can bolt them in place without additional lug crimping. The included 3:1 dual-wall adhesive heat-shrink tubing creates a sealed, strain-reducing cover over the terminal area to protect connections from moisture and abrasion.

• Pre-crimped lugs eliminate the need for lug tools or soldering during install.
• Closed-end lug design protects the conductor from corrosive elements.
• 3:1 adhesive shrink provides a thicker, more durable seal than 2:1 tubing.

Can these cables be used outdoors, on boats, or in vehicles?

Yes—materials selected for the cable and lug construction support outdoor, marine and automotive applications. The EPDM insulation is solvent resistant and the tin coating on the copper lugs improves corrosion resistance in damp or salt-rich conditions.

• EPDM jacket resists oils, fuels and many solvents typically encountered in vehicles.
• Tin-plated lugs reduce oxidation on exposed terminals for longer life.
• Temperature rating and voltage rating suit battery banks, inverters, welders and solar installs.

What accessories and quality checks are included?

Shirbly supplies each cable pair with dual-wall adhesive heat-shrink tubing sized to cover the 3/8" stud area and help ensure a weather-resistant joint. The manufacturing process uses high-strand-count copper for flexibility and consistent electrical performance.

• Pair includes one red and one black 1.5 ft cable for proper polarity identification.
• 3:1 dual-wall shrink tubing included for both cables to seal terminals.
• Shirbly offers customer support for product concerns and post-sale service.

Who is this for: These Shirbly 1/0 AWG battery cables are intended for installers, hobbyists and professionals who need short, high-current power leads for battery-to-inverter, battery-to-welder, battery bank linking, or high-amperage automotive and marine connections. If you require flexible, low-resistance wiring with pre-terminated lugs and weather protection for compact runs (1.5 ft) where space and reliable contact matter, this pair fits those needs. If you need longer runs or different terminal sizes, consider measuring your system first and choosing appropriate AWG length or terminal variants.
