Tinned 12 AWG copper, a 30 amp rating, dual waterproof fuses, and color-coded slide-and-snap ends that go in without cutting or splicing. Simple fix for a charger lead that came up short.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eHere's the situation this cable solves. You mounted your on-board battery charger somewhere convenient, up under the console or back in a lazarette, and then you go to wire it to the battery bank and the factory charger leads come up a few feet short. The Guest 27515 gives you 15 more feet of properly rated DC cable so you can put the charger where it makes sense and still reach the batteries clean.\u003c\/p\u003e\n\u003cp\u003eIt's built the way marine wiring should be. The conductor is tinned 12 AWG copper, so it shrugs off the salt air and damp that eats plain copper alive. The hardware is gold plated for a low-resistance connection that stays that way. And the whole run is protected by dual inline waterproof fuses, so a chafed wire or a bad connection trips a fuse instead of cooking your harness.\u003c\/p\u003e\n\u003cp\u003eThe part boaters actually appreciate is how it goes in. No cutting, no stripping, no splicing. The ends are color coded and use slide-and-snap connection covers that fully insulate each junction. You match red to red, black to black, snap the covers closed, and you're done. It's rated for 30 amps, which covers the draw of just about any on-board marine charger you'd bolt to a boat this size.\u003c\/p\u003e\n\u003cp\u003eThe terminals are universal ring terminals, so they land on standard battery posts and charger studs without adapters. That's the universal part. It's designed first for Guest on-board chargers, where it mates right up to the factory leads, but the ring ends drop onto most any charger and battery setup you'll find on a boat. Twelve and twenty-four volt charging systems are both fair game. You're simply extending the DC run, so the voltage of the bank isn't the concern, the current is, and 30 amps covers the vast majority of on-board chargers out there.\u003c\/p\u003e\n\u003cp\u003eWhere does it earn its keep? Center consoles and bay boats where the charger lives under the leaning post and the batteries sit way back in the bilge. Sailboats routing a charger lead from a stern locker forward to a bank amidships. Any install where the factory cable just won't stretch. We've put these on plenty of boats where the only other option was buying a whole new longer charger or, worse, relocating the one you've got. Repowers and battery-bank upgrades are another common one, where the new bank ends up farther from the charger than the old setup ever was.\u003c\/p\u003e\n\u003cp\u003eThere's a real safety angle to the fusing too. A DC charging run is live any time the charger's plugged in, and 15 extra feet of cable is 15 more feet that can chafe, pinch, or get pinned under gear over time. The dual inline fuses mean a fault opens the circuit right there instead of feeding a short all the way back to the charger. If a fuse ever does blow, you've got a clear signal that something needs looking at, and swapping it is a two-minute job with no tools.\u003c\/p\u003e\n\u003cp\u003eA couple of install notes from experience. On a 15 foot run under a real charging load you'll see a little voltage drop, so keep your main battery cables sized properly and this extension does its job without complaint. Give the connections a shot of dielectric grease when you put it together, especially on a saltwater boat. And anywhere the cable passes through a bulkhead or rubs a stringer, add a bit of split loom or conduit so it doesn't chafe over a season of pounding. Small stuff, but it's the difference between a clean install and a callback.\u003c\/p\u003e\n\u003cp\u003eOne thing to be clear about. This is a power-only extension for on-board charger cables. It carries DC current from point A to point B and protects it with fuses. It isn't a data cable and it doesn't add any features to your charger. It just gets the power where the factory leads couldn't reach. For that job it's exactly the right tool, and it'll outlast a lot of the boat around it.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e15ft length adds reach where factory on-board charger cables fall short\u003c\/li\u003e\n  \u003cli\u003eTinned 12 AWG copper conductor resists corrosion in the marine environment\u003c\/li\u003e\n  \u003cli\u003eRated 30A, covers the draw of most on-board marine battery chargers\u003c\/li\u003e\n  \u003cli\u003eDual inline waterproof fuses protect the run from shorts and chafe\u003c\/li\u003e\n  \u003cli\u003eColor-coded slide-and-snap insulated connection covers, no cutting or splicing\u003c\/li\u003e\n  \u003cli\u003eGold-plated hardware for a low-resistance connection that lasts\u003c\/li\u003e\n  \u003cli\u003eUniversal ring terminals land on standard battery posts and charger studs\u003c\/li\u003e\n  \u003cli\u003eWorks on 12V and 24V on-board charging systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Guest reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow long is the extension?\u003c\/summary\u003e\n    \u003cp\u003e15 feet.
