360AH ULTIMATE WHEELHOUSE LITHIUM POWER PACKAGE
Experience Silent, Stealthy Lithium Power!
The 360Ah Ultimate Wheelhouse Lithium Power Package is engineered to replace traditional lead-acid battery systems in permanent ice fishing houses and support full lithium hydraulic lift and leveling systems. Designed for extreme cold and high-draw applications, this package delivers the stable voltage and high current output required for smooth, reliable hydraulic operation.
BATTERY
At the core of the system are two Norsk Lithium 180Ah starting batteries, wired in parallel to maintain a 12V system while doubling available current capacity. This parallel configuration provides 360Ah at 12V for multi-day power, ensuring sufficient instantaneous amperage to start and operate hydraulic pumps without voltage drop, even in sub-zero conditions. These batteries feature Emergency Reserve (ESR) technology, which protects 25% of total capacity to ensure power remains available for essential systems during extended stays, extreme cold, or delayed recharging.
The system also features complete battery monitoring through the free Norsk Guardian App, giving users real-time insight into battery status, voltage, state of charge, and system health. App-based monitoring provides added confidence and convenience, allowing anglers to easily track power usage and charging performance from their mobile device.
CHARGER
To support fast recovery and consistent performance, the package includes two 12V EVO-TEC™ 2 Bank On-Board Chargers, one dedicated to each battery. Each charger delivers 25 amps of recharge current per battery, allowing balanced, efficient charging while maintaining proper lithium charge profiles. This dual-charger setup ensures both batteries recover quickly after heavy hydraulic use and remain properly maintained during extended stays on the ice.
Once permanently installed, the onboard charging system provides automatic, maintenance-free charging whenever shore power is available – eliminating battery swapping and reducing downtime.
By converting your wheelhouse to a full lithium power system, you gain more usable power, longer runtimes, faster recharge times, reduced weight, longer service life, and dependable cold-weather performance. The Ultimate Wheelhouse Lithium Power Package is the ideal upgrade for anglers who demand modern lithium power and worry-free hydraulic operation in permanent ice houses.
ALL-SEASON USE
The 180Ah Starting batteries and on-board chargers can also be removed and used in other applications, such as a boat during the summer, providing added flexibility and year-round value.
PRO TIP: For multi-day trips, we recommend running your generator during downtime or while you sleep to quickly recharge your batteries. Using the included 2 Bank EVO-TEC™ On-Board Chargers allows you to restore power efficiently, helping ensure your system is fully charged and ready when it matters most.
NORSK GUARDIAN® APP 
Connect to the battery via Bluetooth® and monitor and manage your battery with ease using the free Norsk Guardian® App. View real-time battery status, remaining runtime, voltage, amp draw, and system health. The app also provides access to features like Deep Sleep™ and Emergency Reserve (ESR), giving you complete control from your smartphone.
EMERGENCY START RESERVE 
Never worry about losing power when you need it most inside your ice house. Norsk Lithium® batteries feature Emergency Reserve (ESR) technology that automatically protects 25% of the battery’s capacity for unexpected situations. This reserved capacity ensures power remains available for essential systems such as lighting, electronics, and other critical loads during extended stays, extreme cold, or delayed recharging.
ESR can be accessed directly using the Power Management button on the battery or through the Norsk Guardian® App, giving you added confidence and control in demanding winter conditions.
DEEP SLEEP™ ADVANCED STORAGE MODE 
Easily disconnect power from your battery’s terminals, eliminating phantom current draws and preventing fully-discharged batteries when stored for extended periods of time. This convenient feature eliminates the need to manually operate battery disconnect switches, helping ensure your batteries stay charged and ready when you need them. Wake a battery from Deep Sleep™ mode effortlessly with a quick press of the One-Touch Power Management Button on top of the battery or via the Norsk Guardian® App.
Whether your ice house is parked between trips or stored during the off-season, Deep Sleep™ makes protecting your battery simple and hassle-free.
THERMAL CORE HEATING TECHNOLOGY
Designed specifically for extreme cold environments, Thermal Core Heating Technology™ ensures safe and reliable charging in winter conditions. When connected to a charger, the system monitors internal cell temperature and automatically redirects incoming charge current to warm the cells if temperatures are below 32°F (0°C).
Once the battery reaches a safe charging temperature, normal charging begins. Combined with full potting using thermally conductive epoxy, custom heat pads, and a proprietary heating control algorithm, Norsk Lithium® delivers industry-leading cold-weather charging performance for ice house applications.
BCI-COMPLIANT CASES 
Norsk Lithium 12V batteries are built in BCI-compliant cases, allowing them to fit directly in place of common Group 31 lead-acid or AGM batteries. This makes upgrading to lithium simple, with no need for oversized or proprietary battery trays—ideal for tight ice house battery compartments.
TRIPLE SETS OF TERMINALS FOR FLEXIBLE RIGGING
Norsk Lithium® batteries feature multiple terminal connection points and include the necessary terminal hardware (M8 posts and bolts) to support clean, organized wiring. This flexibility makes it easy to connect multiple loads, chargers, and accessories commonly found in ice house electrical systems.
ONE-TOUCH POWER MANAGEMENT
The Power Management button on the battery allows quick access to key battery functions, including checking state of charge and managing advanced features such as Emergency Reserve (ESR) and Deep Sleep™. This provides simple, on-demand control without requiring a mobile device.
IP67 WATERPROOF
Built for harsh environments, Norsk Lithium® batteries carry an IP67 waterproof rating, protecting against dust intrusion and temporary water exposure. This level of protection ensures reliable operation in wet, icy, and condensation-prone conditions commonly found in ice houses and winter storage environments.
THE NORSK ADVANTAGE
Built by outdoor enthusiasts who understand the demands of cold-weather and off-grid power, Norsk Lithium® batteries are engineered for long-term performance in extreme conditions. Designed to deliver over 4,000 charge cycles and backed by an industry-leading warranty, these batteries provide dependable power season after season.
Every battery includes a standard 10-year warranty, with an additional 2-year warranty extension when registered through the Norsk Guardian® App – ensuring confidence, longevity, and performance wherever your ice house adventures take you.
