Step up to the ultimate in screen brightness, clarity, and unbelievable runtimes

It’s no longer a hi-tech niche product for just a few early adopters. Yes, the use of forward-facing sonar on the ice has gone mainstream with unit costs lowered and the technology optimized for hardwater use. And to those using it, they can’t imagine fishing without it now. Rather than potentially drilling hundreds of holes on an outing, they’re drilling a few and finding fish to set up on top of or intercept.

And with manufacturer and third-party shuttles, backpacks, and sleds optimized to carry the new technology, it’s no longer a matter of how to make the open-water technology work on ice. The biggest problem, really, has been power. Standard flasher batteries don’t make it in this world, and many anglers have found that out the hard way, getting stuck in mid-bite with dark, unusable units. Not fun.

Enter Norsk Lithium®’s take on the entire dilemma, years in refinement to produce two batteries specifically for FF Sonar ice fishing shuttles that provide the ultimate in screen brightness, clarity, and simply unbelievable runtimes. On a weekend trip and forget to plug in your unit after a full-day on the ice? No problem. There’s still going to be juice for another fish-filled day.

THE GOODS: NORSK LITHIUM 14.8V 30AH and 14.8V 50AH

For starters, these two 14.8V batteries provide 20% longer runtime over 12.8V batteries, plus the optimal voltage for manufacturer brightness and clarity specifications. Speaking of manufacturers, the crowd is divided with some ice anglers using Garmin® Panoptix™ or Livescope™, Humminbird® MEGA Live 1 & 2, and Lowrance® ActiveTarget™ 1 & 2.

Want to know the exact runtime these two batteries will produce? Check out the Norsk Lithium Runtime Calculator here and choose the 30AH or 50AH battery from the drop-down menu. From enough power for one dusk ‘til dawn day or a multi-day trip on one charge, Norsk has your power needs covered.

Designed to fit most shuttles, both the 30AH and 50AH batteries are great for extra runtime and the needs of high-power draw FFS units. Plus, you get some great features like use of the Norsk Guardian® App and Deep Sleep™ Advanced Storage Mode.

Once you put one of these batteries inside a shuttle, depending on the design, you might not have easy access to the built-in battery meter to check your status. With the Norsk Guardian® app on your smartphone you can easily view your runtime via the built-in calculator and know down to the minute how much charge you have remaining.

And Deep Sleep™, besides being a great feature for storage, helps anyone using a black box like Garmin and Lowrance users. These black boxes are always drawing current so with Deep Sleep you can ensure there is no stray voltage running your battery down when not in use without disconnecting the battery terminals.
