Sea-Dog 4/0 AWG Red Battery Cable, 50 ft Tinned Copper Spool — Product description

Sea-Dog's 4/0 AWG battery cable in red, on a 50-foot spool of tinned copper. It's the positive-side heavy cable for high-amp DC runs, and it's UL listed and ABYC certified so it meets the standards a surveyor or insurer looks for.

This is Sea-Dog's 4/0 AWG battery cable in red, wound on a 50-foot spool. It's the positive-side cable for heavy DC runs, the wire you reach for when you're feeding a big inverter, a bow thruster, a windlass, or running from the battery bank to a main bus on a larger boat.

The conductor is tinned copper, not bare copper, so it stands up to the salt air and damp that kills untinned wire in a few seasons. Every strand is coated, which keeps corrosion from creeping up under the insulation where you can't see it. That's the difference between a connection that holds for years and one you're re-doing next haul-out.

It ships without terminals, so you cut it to the exact length you need and crimp on your own lugs. It's UL listed and ABYC certified, so it meets the wiring standards that matter on the water. Pair it with the matching black 4/0 for your negative run and you've got a clean, code-compliant DC feed.

Frequently asked questions

Does this cable come with terminals or lugs?

No. It ships as bare cable without terminals so you can cut it to length and crimp on the lugs your install needs.

Why tinned copper instead of plain copper?

The tin coating on every strand blocks the corrosion that salt air and moisture cause in bare copper. On a boat that means connections that stay tight and low-resistance for years.

What is 4/0 gauge cable good for?

4/0 is heavy cable for high-current DC loads: main battery-to-bus runs, inverters, bow thrusters, windlasses, and large house banks.

Is this the positive or negative cable?

Red is conventionally the positive conductor. For the negative side, run the matching black 4/0 cable.
