Spend More of Your Fishing Day Exploring Under Electric Power
When electric propulsion is part of how you fish, available power determines how confidently you can explore beyond the launch, move between productive areas, and keep positioning the boat as the day unfolds. The Newport 36V 48Ah Extended Range Lithium LiFePO4 Battery is made for Newport's compatible NK300 and NT300 motors, giving anglers a dedicated power source designed around longer days of electric kayak and small-boat use.
More Freedom to Fish Beyond the Launch
- ✅ Extended-range capacity gives NK300 and NT300 users more available energy for covering water, exploring, and fishing under electric power
- ✅ LiFePO4 construction delivers dependable, consistent power while avoiding the bulk of a comparable conventional lead-acid battery setup
- ✅ Bluetooth connectivity lets you monitor battery status through the Newport App, making it easier to manage available power as your fishing day develops
- ✅ Built-in battery management and safety protections help manage the battery as part of a properly matched electric propulsion system
- ✅ Marine-focused construction is designed to handle the freshwater and saltwater environments encountered by kayaks and small fishing boats
- ✅ Long-life lithium chemistry supports anglers who regularly depend on electric propulsion rather than treating the motor as an occasional accessory

Real-World Performance
Use the extra available energy to make electric propulsion part of the fishing strategy rather than simply transportation to and from the launch. On a kayak or small boat, that can mean covering a longer shoreline, moving between areas, adjusting position as conditions change, or cruising to the next spot while using the Newport App to keep an eye on battery status.
Give Your Newport Motor More Water to Explore
Pair this extended-range battery with a compatible NK300 or NT300 when you want your electric propulsion setup built around longer fishing days and more freedom to move between productive water.
