Norsk Lithium 12V 105Ah Heated LiFePO4 Deep Cycle Marine Battery

The Norsk Lithium 12V 105Ah Heated LiFePO4 Deep Cycle Marine Battery is built for anglers and boaters who need reliable power in all conditions, including cold weather. The built-in Thermal Core Heating Technology allows the battery to charge in freezing temperatures, so you are not stuck with a dead battery on a cold morning. Bluetooth monitoring through the Norsk Guardian app gives you real-time visibility into battery status, and Deep Sleep mode eliminates phantom draw during storage.

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

What It Does on the Water

At 105Ah, this battery handles high-demand marine electronics, trolling motors, and accessories without the weight penalty of lead acid or AGM. The LiFePO4 chemistry delivers stable voltage throughout the discharge cycle and is rated for 4,000+ charge cycles. The Thermal Core Heating Technology allows the battery to accept a charge even when temperatures drop below freezing, which matters for early spring and late fall fishing in the Brainerd Lakes area.

The one-touch Power Management button lets you check state of charge and manage Deep Sleep mode without opening the app. Bluetooth connectivity pairs with the Norsk Guardian app for full visibility into performance and health.
