About Norsk Lithium

When the bite is on and every second on the water counts, the last thing you want to worry about is your power source. Norsk Lithium was founded by outdoor enthusiasts — anglers and boat owners who know the difference between a productive day on the water and a frustrating one cut short by a dead battery. That real-world perspective shapes everything they design, from trolling motor batteries to portable sonar power packs built for the coldest ice fishing treks imaginable.

What sets Norsk Lithium apart from the flood of overseas battery brands is their direct collaboration with the engineers who develop modern fishing electronics. Rather than building a generic cell and calling it a day, Norsk works alongside platform developers to dial in battery specifications for optimal performance — balancing capacity, size, weight, and environmental resilience for each specific application. Every product is manufactured under strict ISO 9001 quality management standards, ensuring consistent build quality and long-term reliability.

Norsk Lithium's lineup spans an impressive range of use cases. Their lithium batteries cover everything from 12V portable sonar units and kayak setups to high-capacity 36V trolling motor packs, heated ice fishing batteries with Thermal Core Heating Technology™, marine starting batteries, RV batteries, and even boat lift power solutions. Whether you fish open water in July or brave bone-chilling conditions through a frozen lake in January, there's a Norsk battery engineered for the task.

Keeping those batteries performing at their best is where Norsk's lineup of battery chargers comes in. From compact portable chargers with quick-connect harnesses to the advanced EVO-TEC™ on-board multi-bank chargers, Norsk designs their charging ecosystem to work hand-in-glove with their battery chemistry. The result is faster charge times, extended cycle life, and batteries that are always ready when you are.

Norsk Lithium also backs their products with thoughtful technology integrations like the Norsk Guardian™ App and the proprietary Deep Sleep™ mode, giving users real insight into battery health and longevity. For anglers serious about their gear — and serious about putting fish in the boat — Norsk Lithium delivers the kind of dependable, purpose-built power that earns its place on every trip.
