Ancor Marine Grade™ Tinned Battery Lugs — 5/16" Fastener, 1/0 AWG Cable (2-Pack)
Built for the heaviest electrical loads on the water, these Ancor Marine Grade™ Tinned Battery Lugs are engineered for 1/0 AWG cable — the gauge used in high-draw applications like trolling motors, windlasses, and large inverters. Pure copper construction maximizes current flow, while the tin plating provides lasting corrosion resistance in the salt-air and moisture-rich environments that define marine use.
The closed-end barrel seals the wire tip against moisture ingress, eliminating one of the most common causes of connection failure in marine electrical systems. Whether you're terminating a battery bank, replacing worn lugs on a high-output alternator, or building a clean shore power connection, these lugs are rated for the job.
Compatible Applications
- Trolling motor and electric motor battery terminations
- Windlass and anchor winch wiring
- Large inverter and converter hookups
- High-output alternator connections
- Battery bank and dual-battery system builds
- Shore power and generator wiring

Parts Desk Insights
1/0 AWG is a heavy-gauge cable used in high-current runs — typically 100A and above — making proper termination critical. These lugs are the right choice when you need a permanent, low-resistance connection at a battery post, bus bar, or motor terminal. The closed-end design is especially important at this gauge: large-diameter wire bundles are more susceptible to moisture wicking, and an open barrel leaves the wire tips exposed. Sold as a 2-pack, which is well-suited for a single battery connection (positive and negative) or as a matched pair for a motor run. For full system builds, consider stocking the 25-pack battery lug options alongside this product for smaller gauge runs.
