Frequently Asked Questions

What Dakota Lithium battery do I need for my trolling motor?

Choose a battery based on your trolling motor's required voltage, current draw, desired runtime, and the battery's continuous discharge capability. Dakota Lithium offers batteries for different trolling motor applications, so always compare the motor's specifications with the specific battery's ratings. 

How many amps does my trolling motor draw, and how does that affect battery selection?

Your trolling motor's maximum current draw helps determine the battery's required continuous discharge capability. The battery should be capable of supplying the motor's required current without exceeding its specifications. Battery capacity in amp-hours also affects how long the motor can operate before the battery needs to be recharged.

What is the difference between a Dakota Lithium deep cycle and Dual Purpose marine battery?

A deep cycle marine battery is designed primarily for sustained energy and repeated cycling, such as powering a trolling motor or electronics. A Dual Purpose battery is designed to provide both sustained power and engine-starting capability. Choose based on whether your application requires deep-cycle power, starting power, or both.

Can I use a Dakota Lithium battery for both my boat's engine and trolling motor?

It depends on the battery and your boat's electrical system. A battery designed for both starting and sustained power may be suitable for certain applications, while a dedicated deep cycle battery is generally intended for sustained loads such as trolling motors. Always verify the battery's cranking, continuous-current, capacity, and charging specifications.

Can Dakota Lithium batteries be used in saltwater environments?

Dakota Lithium batteries can be used in many saltwater marine applications when properly installed and protected. The battery should be kept in a secure location and protected from direct exposure to water, salt spray, and excessive moisture.

Make sure all terminals, connections, wiring, and other electrical components are properly protected against corrosion and moisture. Proper installation and maintenance are especially important in saltwater environments.

Always follow the installation and environmental specifications for your specific battery model.
