Ancor 4 AWG Tinned Copper Battery Cable Assembly — 48", Red
A ready-to-install battery cable built for the demands of the marine environment. This 48-inch red positive cable is assembled with premium UL 1426-rated tinned copper wire and factory-crimped tinned copper lugs — delivering a corrosion-resistant, high-current connection right out of the box. No crimping tools, no guesswork.
Each lug end is sealed with Ancor's adhesive-lined 3:1 heat shrink tubing, locking out moisture, salt, and corrosive vapors at the most vulnerable point of any cable run — the termination. Rated to 600V and 105°C, this assembly meets the rigorous standards required for marine electrical systems.

Parts Desk Insights
This 48-inch red assembly is the most popular length for battery bank connections on mid-size powerboats and sailboats — long enough to reach across a typical battery compartment without splicing. The 4 AWG gauge handles up to 95–100A continuously, making it well-suited for trolling motors, inverters, and starter circuits on smaller engines. If your run is shorter, the 32" version (189135) keeps things tidy. For higher-draw applications like large inverters or twin-engine starters, step up to the 2 AWG, 48" assembly (189147). Always pair red (positive) cables with the matching black negative (189136) for a complete, code-compliant installation.
