DON’T FISH LIKE A CAVEMAN!

What do you need to get the most out of your ice-fishing electronics and maximize your day on the ice? Power.  Reliability.  Light-weight efficiency. 

The Norsk Lithium 15Ah Battery delivers.  Our best-selling lithium ion battery pummels the competition.  On its watch, most common sonar units with screens up to 7″ thrive with over 15 hours of runtime.    

Weighing in at merely 2.6lbs, Norsk’s 15Ah lithium battery is more than three times lighter than a lead-acid battery equivalent.  

When your flasher tells you the best bites are waiting across the lake, you don’t want to be stuck hauling acid across the frozen water.  You need to pack up and move.  Quickly.   

The compact size (5.94 X 2.56 X 3.66 In) is expertly designed to be the perfect drop-in replacement to upgrade your ice-fishing electronics and provide the performance you deserve.  

THE NORSK ADVANTAGE

Outdoor fishing enthusiasts engineer our batteries.  We make the best rechargeable lithium-ion battery – because we want the best technology to power our passion.  

We don’t have time or money to waste on cheap, unreliable, ancient batteries.  

The Norsk 15Ah lithium ion battery will run for more than 1,000 charge cycles and comes with a two-year limited warranty.  

STANDARD LITHIUM ION BATTERY FOR HUMMINBIRD!

The Norsk 15Ah lithium ion battery is the standard power source for Humminbird’s Ice Helix 7 CHIRP GPS G4 All Season

No battery on the market can compete with what Norsk Lithium offers. 

BATTERY MONITORING SYSTEM (BMS)

The Norsk 15Ah Lithium Battery comes equipped with a BMS system that makes it fool-proofed and worry-free.  

The BMS won’t allow the battery to receive a charge until its internal temperature has warmed to a safe 32F.  Once it’s safe, the BMS will allow the lithium battery to recharge, and you’ll be on your way!

Our advanced BMS technology prevents your Norsk 15Ah lithium ion battery from overcharging.  

Even if you completely hook up your lithium-ion battery charger to the wrong terminals, the BMS will prevent it from receiving any charge.    

The BMS ensures cell balancing during discharge and charge cycles, low and high voltage cutoff, short circuit protection, and high-temperature protection. 

DUAL USB PORTS

Just because cavemen caught fish doesn’t mean you must fish like a caveman.  

The Norsk 15Ah Lithium battery’s patten-pending, dual USB ports allow you to enjoy the outdoors in the 21st century. 

These allow you to power your cell phone, go-pro, or nearly any USB-compatible device while your lithium battery powers your fish finder.  

BATTERY POWER INDICATOR

The Norsk 15Ah lithium battery has an enormous runtime.  But it will run out of juice.

With the LED power indicator, you can know when.  Just press the button, and the LED Power indicator will let you know how much power your lithium battery has left. 

THE RIGHT LITHIUM CHEMISTRY FOR THE RIGHT APPLICATION

Lithium-ion chemistry is the best choice for maximizing your ice-fishing experience.  Many lithium batteries will use LiFePO4 in their ice-fishing applications.  

We also use LiFePO4.  It’s excellent.  But it has a slight weight problem.  

Lithium-ion chemistry provides exceptional power while also offering a significant weight advantage.  Lithium-ion batteries have one of the highest energy densities of any battery technology currently available.  

The Norsk 15Ah lithium battery is remarkably potent – and so light – you’ll barely notice it when you charge across the ice to the best spot for feeding time!

    15AH Lithium-Ion Battery

    dave.koonce (verified purchase)

    This battery has a lot of juice !! Long lasting power when used with my Helix Ice 7. My first outing was on Mille Lacs and I had about 16 hours of use in two days and it still had 3 out of 4 lights left on the power indicator. Having the two USB ports allowed me to charge up my phone too… I can see multiple uses for having those ports for sure !! I ordered this battery on-line and it was shipped out the next day via Spee-Dee Delivery … Fast Turn Around !!

    I had this out for a day and a half trip on the lake and ran my Helix 7 the entire time. I also ran lights off the usb port for multiple hours. This still had a charge when I left.

    I love this battery. It was shipped super fast! I used it in my Vexilar for two days and its still shows 4 out of 4 for charge left in the battery. I’m amazed at weight difference compared to my regular Vexilar battery.

    Could have given it a 5 star

    JOHN (verified purchase)

    I am impressed with the light weight in the standard size for ice fishing locators. After using it this winter I am still confused how the voltage indicator on my Lowrance unit drops .1 volt per hour and is down to 11.3 volts after 7 hours but the indicator on the Norsk battery still shows 3 of 4 lights on. I was told by Norsk that my unit was not calibrated for a Lithium battery however Lowrance disagrees. This is the only reason I did not rate 5 stars.

  13. My Favorite Battery By Far!

    mannyt (verified purchase)

    Can’t get enough of these batteries – I actually bought 2. One for the house and one for fishing! The USB’s are a huge added bonus – my wife uses one to charge her phone next to the couch.

    This is by far the best battery on the market for running our ecallers. Long run time and so light makes for easy in and out of muddy fields in the spring. We charge once every three days now instead of every night. 👌👌👌

  17. Light in weight

    Vince Riedl

    Shipping was done in a timely manner. (2-3 days) I really like how light my 15ah battery is compared to my older lead acid batteries. The USB ports incorporated are a good idea, I’m sure they will be popular. Im just waiting on some decent ice to run the Helix 7 and check out the run time on the battery.

    I worked with Jakob who was incredibly responsive. He sent me various products so we could quickly troubleshoot and solve the problem with the charger for my 15H battery which I use with my Humminbird fish finder.

  22. Great Customer Service

    Dave Inman

    Left charger at cabin. Battery at home without charger lost charge eventually. Tried charging with other chargers and even went to a Battery Store and nothing worked. Finally thought to call Norsk customer service and they sent out a replacement Norsk charger at no cost. Battery immediately charged back up. I am amazed that it worked and that Norsk customer service was so responsive. Great Company.
