Norsk Lithium

Built by Anglers, Engineered for the Water

Norsk Lithium is a marine and outdoor power brand with a singular focus: delivering lithium battery technology purpose-built for anglers and on-the-water adventurers. Unlike generic battery manufacturers, Norsk is rooted in the fishing community — a team of outdoor enthusiasts who understand the demands of a full day on the water, from bone-jarring runs across a frozen lake to marathon bass fishing sessions in summer heat. That lived experience drives every design decision the company makes.

Norsk Lithium batteries are engineered in close collaboration with the developers of today's fishing electronics, ensuring each battery is optimized for the specific platforms anglers rely on — from portable sonar flashers to high-draw live imaging systems. The result is a lineup that carefully balances capacity, physical size, and weight without compromising performance. All Norsk batteries are manufactured to strict ISO 9001 quality standards, a commitment that underpins their industry-leading warranty coverage.

Technology That Sets Norsk Apart

Norsk Lithium packs several proprietary technologies into their batteries that address real-world problems other manufacturers overlook:

• Thermal Core Heating (TCH) Technology — Raises the internal battery temperature to a safe threshold before allowing charging, enabling reliable operation in freezing conditions where other batteries simply fail.
• Advanced Battery Management System (BMS) — Protects against overcharging, crossed terminals, short circuits, high temperatures, and improper cell balancing, preserving battery health over thousands of cycles.
• Deep Sleep™ Mode — Disconnects power from battery terminals to eliminate phantom current draws during storage, preventing fully-discharged batteries between trips.
• Norsk Guardian® App — A Bluetooth-connected companion app that lets anglers monitor battery health, charging status, and temperature in real time across multiple batteries simultaneously.
• Emergency Start Reserve (ESR) — Available on starting battery models, this technology reserves 25% of capacity to ensure you can always start your outboard, even after a full day on the water.

A Complete Power Ecosystem

Beyond their core battery lineup, Norsk extends their power philosophy into battery chargers with the EVO-TEC™ series of on-board chargers. These intelligent chargers support selectable battery chemistry — Lead Acid, AGM, or Lithium — and switchable voltage on select models, making them a versatile fit for mixed-battery setups. Portable charger options round out the lineup for anglers who need convenient charging away from the dock.

For those who power their fishing from a fish finder, sonar unit, or live imaging display, Norsk's marine electronics power solutions deliver the consistent, reliable voltage these sensitive devices demand. Whether you're running a portable flasher on the ice or a multifunction display on a bass boat, Norsk has engineered a battery specifically for that application.

Norsk Lithium's approach — combining real-world angling expertise with rigorous engineering and smart technology — has made them a trusted name among serious freshwater and ice fishing enthusiasts across the United States and Canada.
