NORSK 14.8V Lithium-Ion Battery With Charger - 50AH

The Norsk Lithium 14.8V 50Ah Lithium-Ion Battery is the most powerful portable sonar battery in its class—purpose-built to deliver extended, uninterrupted runtime for high-demand forward-facing sonar systems. Designed for anglers who rely on advanced imaging technologies like Humminbird MEGA Live Imaging™, Garmin Livescope™, and Lowrance ActiveTarget™, this battery ensures your electronics stay powered longer, so you can focus on fishing, not power management.

With 740 watt-hours of energy storage, this battery offers unmatched capacity in a compact form factor—ideal for full-day use or multi-day trips without access to shore power. Whether you’re chasing fish across large bodies of water or using multiple graphs and sonar units simultaneously, the 50Ah battery delivers consistent, high-output performance without voltage dropouts or system lag.

Built for real-world conditions, the battery features dual IPX8-rated waterproof USB-A and USB-C ports, allowing you to charge phones, cameras, and other accessories directly from the battery—even in wet, harsh environments. The upgraded charge status display gives you a clear, real-time view of your remaining capacity, making it easier to manage power levels throughout the day.

To further extend shelf life and reliability, the battery includes Deep Sleep™ Mode—an advanced low-power setting that electronically disconnects the terminals to eliminate parasitic drain during storage. This ensures your battery retains its charge for months at a time, ready to perform when you need it most.

Integrated Bluetooth connectivity lets you pair the battery with the Norsk Guardian® App, providing remote access to vital stats like voltage, current draw, and temperature—all from your smartphone. Whether you’re monitoring usage trends or checking charge levels between casts, the app gives you complete control and peace of mind.
