DC Cable Extender for Marine Battery Chargers — 15 ft / 30A
When your on-board battery charger can't reach a bow, center-mount, or stern battery compartment, this 15-foot DC cable extender bridges the gap without any cutting, stripping, or splicing. Designed to work with all on-board marine battery chargers, it installs in minutes and delivers a secure, weatherproof connection rated to 30 amps.
Built with corrosion-resistant tinned 12 AWG copper wire and gold-plated hardware, this extender is made to hold up in the harsh marine environment. Dual inline waterproof fuses protect the wiring at both ends, and color-coded leads with slide-and-snap insulated connection covers make installation straightforward even in tight spaces.
