Norsk Lithium® Launches a Huge Free Update for Their Norsk Guardian™ App
The smartphone has become an indispensable tool for modern anglers, offering GPS-enabled mapping apps, cameras to document catches, and social platforms to track bite patterns and connect with fellow anglers.
Norsk Lithium® has redesigned its Norsk Guardian™ App to enhance the user interface, delivering an improved user experience for controlling, monitoring, and organizing Norsk Lithium batteries. Unlike other apps anglers rely on for mapping or social networking, Norsk Guardian™ focuses on providing real-time performance metrics, health alerts, and seamless connectivity to ensure batteries perform at their best—whether on the water or off the grid.
Norsk Lithium listened to customer feedback and responded by adding Bluetooth® to the 14.8V line of Portable Sonar Batteries (Gen3), a feature previously only available in the Marine Battery line. This upgrade is a game-changer for hard water anglers, providing seamless connectivity to their portable sonar systems. With Bluetooth® integration, the Norsk Guardian™ App now connects to all Norsk Lithium Marine and 14.8V Portable Sonar Batteries (Gen3), allowing users to monitor key performance metrics and receive critical health alerts, ensuring peak performance in any season.
The main dashboard has been completely redesigned. Now you can sort your batteries into four categories; Marine, Recreational Vehicle, Sonar, and Off-Grid. Once you connect to a battery you can assign it to a group within those four main categories. These sub-categories give you more control over your marine battery setups. For example, suppose you separate your batteries into a trolling motor group and a starting battery group. In that case, you can put your trolling motor batteries into Deep Sleep and leave your starting battery on with an automatic bilge pump for overnight docking. You won’t find this level of functionality in any other lithium battery app.
“It’s the only app that allows the user to display battery data from batteries connected in serial or parallel. We’re the only app that allows users to connect and view data from multiple batteries at one time and display it all on one page,” says Norsk VP of Strategy & Development, James Holst.
Holst continues: “You look at your phone and you have all the battery information from an entire boat battery installation – even 6, 8, or 10 batteries in one boat – and they’ll all be visible on one screen and you can see what they’re all doing at one time. Other battery apps require users to connect and disconnect to monitor each battery’s health. Or, if they do allow you to connect to more than one battery, they cannot monitor batteries connected in series or parallel. They only show you standalone batteries.”
Many anglers are putting together shuttles for their live imaging sonar systems. Instead of guessing how much time you have left from a shuttle voltage meter, you can let Norsk Guardian™ handle the math and tell you exactly how much time you have left down to the minute with the Runtime Calculator. Check your remaining runtime in seconds and get back to fishing.
The Norsk Guardian™ App offers an impressive array of features, providing serious anglers with powerful tools to enhance their time on the water.

NEW! ACTIVATE DEEP SLEEP™
With the Deep Sleep™ feature in the Norsk Guardian™ app, you can easily disconnect power from your batteries’ terminals, eliminating phantom current draws and preventing fully discharged batteries. This convenient feature saves you from having to manually activate battery disconnect switches, ensuring your batteries remain charged and ready to use. Perfect for seasonal storage and traveling.
NEW! ACTIVATE EMERGENCY START RESERVE [ESR]
Norsk Lithium® Starting Batteries offer an Emergency Start Reserve [ESR] that allocates 25% of the battery’s capacity as a reserve available on demand so you’ll always have the power to start your outboard motor. With the Norsk Guardian™ app, you can easily access [ESR] from the convenience of your phone or with the power management button on top of the battery itself.
NEW! INTEGRATED LIVE CHAT
Norsk Lithium® is committed to delivering exceptional customer service. Users can connect directly with a US-based Norsk Lithium representative through the app for troubleshooting assistance or to address any general questions—all from the convenience of their smartphone. This commitment ensures every customer receives the support they need, whenever they need it.
Holst concludes: “The Norsk Guardian™ app is also not a re-skinned app. It was built from the ground up to control our batteries. It allows users complete control of all major features and functions of the batteries, like Deep Sleep™. With the press of one button of the app you put all of the batteries in your boat to sleep and ready for storage up to a year. Nobody but Norsk has these capabilities. It’s about ease of use, convenience, and peace of mind, something we understand as anglers ourselves.”
NORSK LITHIUM ® MAKES BETTER THE BEST WITH IMPROVED FEATURES & LONGER WARRANTY
“Everything about our portable battery line-up has been re-designed and improved,” says Norsk Lithium VP of Strategy & Development, James Holst. “And we’ve been able to make all of the improvements to the features, internal components, and overall safety of our products without having to raise our prices.”
Starting with the 14.8 volt line, over the past couple of years discerning anglers have gravitated to Norsk’s higher voltage “orange” batteries due to the increased efficiency and longer runtimes for running everything from 7-inch displays up to 15-inch screens with live imaging/FF sonar and MEGA 360.
The first feature the company has added is Bluetooth® technology, allowing users to connect to the battery via the Norsk Guardian® app, providing anglers the runtime calculation to determine how much longer they can keep their sonar units powered.
“At a glance, you can see the state of charge which is super important with lithium batteries because it’s the only reliable way you can check the remaining runtime of the battery. Case in point, like when a battery is enclosed in a sonar shuttle that has a built-in voltage meter. In this common scenario the angler might be lead to believe that the built-in voltmeter is a good way to check remaining runtime, but nothing could be further from the truth. For example, if the voltmeter shows 13.7V you could be anywhere from a 30% state of charge to a 70% state of charge because the discharge curve is so flat.”
Monitoring the state of charge via the free Norsk Guardian app available for both IOS and Android provides an estimated runtime calculation that is highly accurate and adjusts as the demands of the sonar unit change as is the case when the user adjusts screen brightness.
For those that don’t want to use an app to check state of charge, all 14.8V Norsk portable sonar batteries come with a built-in battery meter that can be used to quickly check state of charge with the push of the Battery Management button found on the top of each 14.8V battery. `The built-in State of Charge (SOC) Indicator panel is incredibly handy and easy to use — and does a lot more than simply show the user the current SOC when they push the Battery Management button. For instance, the SOC Indicator panel will also indicate if a charge is taking place and show the current SOC as the battery accepts the charge. If you’re at 25% state of charge, one light will flash and when you’re at 50% state of charge two lights will flash, simulating the feature set of power tools like drills that you already use at home.
Norsk also added two IPX8 waterproof USB ports to the battery, which means if you expose the battery to water through ice fishing or kayak fishing all you have to do is wipe them dry and you’re good to go. The batteries have an IP67 rating so they are waterproof down to four and a half feet of water for 30 minutes.
“That’s overkill in some ways, but we wanted to build the absolute best lithium battery for the sloppiest conditions an ice angler might encounter.”
Holst continues: “Norsk Lithium has also upgraded their battery composition to LG cells, the highest quality lithium cells on the market today. And we’re so confident in the build quality of our portable sonar batteries that we’ve extended our base 2-year warranty to 4 years on our 14.8V batteries, which can be extended to six years if the customer registers their battery through the Guardian App. Consumers are going to love the value of having 6-year coverage on a portable sonar battery.”
The extended warranty isn’t just for Norsk Lithium’s 14.8V 32Ah and 50Ah batteries either. Their 12.8V 10 and 15Ah batteries now feature a 4-year warranty. Long gone are the days of replacing your sonar batteries every year.
Every Norsk Lithium Portable Sonar Battery now comes with an upgraded charger that matches the battery case color of the specific model – green for green 12.8V batteries and orange for orange 14.8V batteries so users can’t use the wrong charger. And even if someone were to use an orange charger with a green battery and vice versa, the battery chargers are “smart” to prevent accidentally damaging the battery.
Norsk Lithium has also added cold temperature protection, so if the battery is too cold to charge, you can connect the charger and it won’t start charging. All you have to do is let the battery warm up naturally and when it reaches a safe temperature for charging the charger will automatically turn on and charge the battery normally—no customer interaction required.
Shuttle-Ready Wiring
New for 2025, Norsk also added full SAE connections from battery to charger so if you’re putting a battery in a shuttle It comes with the included SAE wiring cable set required without buying anything extra.
Increased Safety & Easy “Summer-izing”
“We’ve tremendously improved the safety of our batteries, too,” adds Holst. “Every portable sonar battery now uses internal cell racking as opposed to lithium battery manufacturers who only wrap their cells in paper and tape with little if any space between them. Cell racking provides space between cells for cooling, minimizing the chance that something could go wrong. We’ve also managed vibration to keep our cells where we want them in the battery case which is made of the same polycarbonate material that bulletproof windows are composed of. The ABS plastic used by a lot of other manufacturers actually absorbs water; not the case with our material,” offers Holst.
“We also added Deep Sleep to our portable batteries, an automatic storage setting you can engage from a button on top or via the Guardian app. So, all you have to do to ‘summerize’ the battery is remove connectors from the terminals and hit a button. It’s a great way for ice anglers to put the battery into storage and now it will be good to go the following season.”
One of the biggest trends in ice fishing is supplying higher voltage portable sonar batteries to today’s ice sonar for longer runtime, better operation, brighter screens, and better fish/lure imaging. At first, anglers used the 12.8V batteries we recommend for flashers but have discovered that our higher voltage 14.8V portable sonar batteries provide longer run times per amp because your equipment runs so much more efficiently; 20 to 25% runtime advantage per amp hour. You don’t need to have a 20-pound battery to run live imaging. We offer a 50 amp hour portable sonar battery and our 14.8 volt lineup that weighs right around seven pounds, about the third the weight of a lead acid battery, much longer runtime, and all the cool features mentioned above.
NORSK LITHIUM: WE’VE GOT YOU POWERED!
No matter what you’re using to fish, Norsk Lithium has designed power solutions that are optimized for whatever ice fishing electronics you’re using—from mechanical flashers to today’s most advanced forward-facing sonar.
