Norsk Lithium Sonar Battery with Charger Batteries

The Norsk Lithium Portable Sonar Battery with Charger line gives anglers a lightweight lithium power source for fish finders, flashers, GPS units, and live imaging or forward-facing sonar systems. Each battery ships with a 3A charger, so it is ready to use. Together they replace a heavy lead-acid (SLA) battery and give you a portable sonar battery for open water and ice fishing.

Key Features:

• Lithium chemistry: The line includes 12.8V LiFePO4 models and 14.8V lithium-ion models. The 12.8V models are compact drop-in replacements for SLA batteries. The 14.8V models are built for live imaging sonar such as Humminbird MEGA Live Imaging, Garmin LiveScope, and Lowrance ActiveTarget.
• IP67 waterproof construction: The case is dust-tight and can be immersed in water, so it holds up in rugged outdoor and marine conditions.
• Advanced protection: Internal cell racking and a battery management system (BMS) protect the battery during use and charging.
• Long service life: Rated for 2,000 or more charge cycles. Norsk says the batteries last up to four times longer and charge up to five times faster than lead-acid.
• Smart features on select models: These include Bluetooth monitoring through the Norsk Guardian app, Deep Sleep storage mode, state-of-charge indicators, and waterproof USB ports.
• Color-coded smart charger: The included charger is matched to the battery's case color to help prevent using the wrong charger.

Norsk Lithium portable sonar batteries are designed for steady power across a long day on the water, with strong power-to-weight performance. Choose the model that suits your electronics and runtime needs.
