Power Your Trolling Motor Without Hauling a Heavy Battery
Keeping a kayak or small fishing boat powered should not mean giving up valuable carrying capacity to a bulky battery. The Newport 12V 50Ah Lithium LiFePO4 Battery gives anglers a compact power source for compatible trolling motors and onboard marine accessories, making it easier to build a lighter, more manageable electrical setup for a day on the water.
Built Around the Way Anglers Use 12V Power
- ✅ Cuts down the battery weight you have to load, carry, and position compared with a conventional lead-acid marine battery
- ✅ Delivers consistent LiFePO4 power for compatible trolling motors and onboard marine accessories
- ✅ Bluetooth monitoring lets you check battery status from the Newport Battery App instead of relying on guesswork about remaining charge
- ✅ Built-in battery management helps protect and manage the battery while powering a properly matched marine electrical system
- ✅ Compact construction makes the battery easier to work into kayaks, skiffs, and small boats where storage space matters
- ✅ Long-cycle LiFePO4 chemistry makes it a practical rechargeable power source for anglers who regularly run electric propulsion or marine accessories

Real-World Performance
On a fishing kayak, skiff, or small boat, reducing battery bulk leaves more of the setup focused on fishing gear, propulsion, and usable space. Connect the battery to a properly matched trolling motor or accessory system, then use Newport's Bluetooth app to monitor charge level, current, voltage, and cycle count while keeping tabs on the power system throughout the day.
Build a More Manageable 12V Fishing Setup
Use the Newport lithium battery as the compact power foundation for a properly matched trolling motor or marine accessory system when saving weight and monitoring battery status both matter.
Frequently Asked Questions About the Newport 12V 50Ah Lithium Battery
Can I use this battery with a trolling motor?
Yes. Newport designs this battery for trolling motors and onboard marine accessories, but the connected equipment must match the battery's electrical limits. Confirm the voltage and current requirements of your specific motor or accessory before connecting it.
Does the Newport 12V 50Ah lithium battery include a charger?
No. A charger is not included. Newport recommends charging the battery with an appropriate 12V LiFePO4 battery charger.
What can I monitor with the Newport Battery App?
The Bluetooth connection lets you view information including state of charge, current, voltage, cycle count, and rated capacity from the Newport Battery App.
Can this lithium battery be used as a starting battery?
No. Newport specifically states that this battery is not intended for starting devices and should not be used as a starting battery.
Can I connect two Newport 12V 50Ah batteries together?
Newport supports up to two qualifying identical batteries as either a 24V 50Ah series system or a 12V 100Ah parallel system. The batteries must meet Newport's connection requirements, including matching capacity and BMS, being the same brand, and being purchased within one month of each other.
