Norsk Lithium 36V + 28V 60Ah Dual Voltage Heated LiFePO4 Lithium Battery

The Norsk Lithium 36V + 28V 60Ah Dual Voltage Heated LiFePO4 Battery is a single battery that powers both your 36V trolling motor and your forward-facing sonar system from dedicated terminal sets. The 36V terminals connect directly to your trolling motor. The 28V terminals power your sonar module, running it cooler and giving you longer runtime compared to a 12V power source. Built-in Thermal Core Heating Technology allows the battery to charge in freezing temperatures, and Bluetooth monitoring through the Norsk Guardian app gives you real-time visibility into battery status.

Warranty: 10 years standard, extendable to 12 years with Norsk Guardian app registration.

What It Does on the Water

Running a 36V trolling motor and a forward-facing sonar system typically means managing two separate batteries. This battery eliminates that by providing both voltages from a single unit. The 28V sonar output is a key differentiator: it runs your sonar module cooler than a 12V source, which can extend the life of the unit and improve runtime. At 60Ah, it gives you all-day capacity for both systems without the weight of two separate batteries.

The Thermal Core Heating Technology allows the battery to accept a charge even when temperatures drop below freezing. Deep Sleep mode eliminates phantom draw during storage, and the one-touch Power Management button lets you check state of charge without opening the app.
