ProMariner 51815 Universal DC Cable Extender, 15 Foot, 30 Amp, Ring Terminal

The ProMariner 51815 is a 15 foot DC cable extender built to universally extend the reach of onboard marine battery chargers that use ring terminal cables. When a standard charger's cables cannot reach a bow, center mount, or stern battery compartment, this extender adds the length needed to complete the connection without cutting, stripping, or splicing any wire. It is rated up to 30 amps and constructed from corrosion resistant tinned 12 AWG copper wire with gold plated hardware for a reliable, long-lasting connection in a marine environment.

Installation is designed to be fast and foolproof: the cable is color coded so the correct polarity connections are easy to identify, and slide-and-snap fully insulated connection covers protect each joint once connected. Dual inline waterproof fuses are built into the extender for added wire protection. Because it is universally designed for marine chargers with ring terminal cables, the ProMariner 51815 works with a wide range of onboard charger installations rather than a single specific model.
