DON’T SETTLE FOR CHEAP KNOCK-OFFS AND ANCIENT TECH
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 20.8Ah Battery delivers. Our lithium ion battery pummels the competition.
Weighing in at merely 4.2lbs, Norsk’s 20.8Ah lithium battery is three times lighter than a lead-acid battery equivalent. With Norsk powering your passion, you can be mobile on the ice.
When your sonar unit shows you that the best bites are waiting across the lake, you shouldn’t be stuck hauling acid across the frozen water. You need to pack up and move. Quickly.
The compact size (5.9 X 3.85 X 3.70 In) is expertly designed to upgrade your ice-fishing electronics and provide the performance you deserve.
Even with the efficient size and weight, the Nork Lithium 20.8Ah battery delivers unmatched power and runtime.
Our high-quality lithium-ion battery cells provide maximum power without any degradation. This lithium ion battery will light up your live imaging units with the same effectiveness from its first 10% to its last.
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 20.8Ah lithium ion battery will run for more than 1,000 charge cycles and comes with a two-year limited warranty.
STANDARD BATTERY FOR THE HUMMINBIRD ICE HELIX 9 MEGA LIVE
The Norsk 20.8Ah Lithium Ion Battery is engineered to meet the demand for high-power draw digital units with larger displays and is optimized for all-day performance.
This is the best lithium ion battery for Humminbird Mega Live, Garmin Livescope, or Lowrance Active Target.
BATTERY MONITORING SYSTEM (BMS)
The Norsk 20.8Ah Lithium Battery BMS makes it fool-proofed and worry-free. As a lithium ion battery ought to be.
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 also prevents your Norsk 20.8Ah lithium ion battery from overcharging.
Even if you 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 them.
The Norsk 20.8Ah 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 20.8Ah 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 20.8Ah 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!

Great battery! Had it powering my Humminbird Solix 10 G3 on a fly-in fishing trip – all day usage was not an issue. Even better than the battery was the customer service, charging became an issue, without hesitation they resolved the issue!

As the 2024 kayak tournament season kicks off, I’ve been pleasantly surprised with how durable this battery is! I’ve gone multiple 8hrs days of fishing with out having to recharge. This is a great option for when camping out for a tournament and I do t have electricity to recharge the batteries for me electronics.
