Lithium Batteries

The best trolling motor battery depends on your motor and how long you fish. For Newport trolling motors like the NV Series and Kayak Series, a 12V 50Ah deep cycle marine battery is the reliable, affordable choice.

Newport LoPRO Lithium batteries are our premium tier — featuring a lower profile design, higher capacity, real-time Bluetooth monitoring via the Newport Battery App.

Standard Newport lithium batteries deliver reliable LiFePO4 performance at a more accessible price point. Both are a significant upgrade over lead acid deep cycle batteries in weight, runtime, and cycle life.

Voltage depends on your specific motor. Newport trolling motors (NV Series, Kayak Series, X Series, L Series) run on 12V. The NK180 HD kayak motor requires 24V. The NK300 HD and NT300 electric outboard require 36V. The NT600 electric outboard requires 48V. Always match your battery voltage to your motor's requirements for safe, optimal performance on the water.

Yes. Newport LiFePO4 lithium batteries are built for marine use in both freshwater and saltwater environments. LiFePO4 chemistry is one of the safest lithium battery types available

Yes. Newport offers two expansion options exclusively for LoPRO Lithium batteries. The LoPRO Voltage Expansion Kit ($139.99) connects two LoPRO batteries in series using heavy-duty 8 AWG marine-grade cables with plug-and-play IP67 compression terminals — doubling your voltage while maintaining amp hours. Supported configurations include 2 x 24V = 48V, 2 x 36V = 72V, and 2 x 48V = 96V.

The LoPRO Runtime Expansion Kit ($299.99) connects two matching LoPRO batteries in parallel to double your amp hour capacity while keeping voltage the same — ideal for anglers who need longer runtime on large reservoirs, open bays, and extended fishing days. Supported configurations include 2 x 12V 100Ah = 12V 200Ah, 2 x 24V 50Ah = 24V 100Ah, and 2 x 36V 50Ah = 36V 100Ah. Both kits require matching LoPRO batteries of the same voltage and amp hour rating.
