What are the different types of trolling motor batteries?

There are generally three main types of trolling motor batteries: lead-acid batteries, AGM batteries, and lithium-ion (LiFePO4) batteries. Below, we will delve into the specific advantages and limitations of each type. The most prevalent type of battery utilized for trolling motors is the lead-acid wet cell battery.

How to choose a lithium trolling motor battery?

But you’ll still need to figure out the ideal size of your battery. When shopping for lithium trolling motor batteries, you’ll need to consider amperage and voltage. The larger the motor, the higher capacity you’ll need in its battery. For optimal performance, look at your manual or speak to the manufacturer for guidance.

How many batteries does a trolling motor need?

More batteries of the same size mean more capacity and more range available. As a rule of thumb, trolling motors with 55 lbs of thrust or less operate on 12 volts (single battery), those with 68-100 lbs of thrust run on 24 volts (two batteries), and those above 100 lbs of thrust require 36 volts in total (three batteries).

What are the benefits of lithium trolling motor batteries?

Another benefit of the reduced weight is the ability to draft in shallower water, potentially into back-water areas with lower fishing pressure. Another notable advantage of lithium trolling motor batteries includes longer run times without battery voltage drop and the potential for quicker charging cycles.

How much do trolling motor batteries cost?

You can find small, inexpensive trolling motor batteries decent for small boats, like kayaks or canoes, that cost less than $25. On the other hand, many larger, more powerful trolling motor batteries can cost well over $500 and even over $600.

How do I choose a deep cycle battery for my trolling motor?

We suggest selecting a 12-volt deep cycle marine battery with at least 110 amp hour rating. Usually Group 27 size or larger. The higher the amp-hour rating, the more run time your trolling motor will receive. If an amp hour rating is not available, select a deep cycle battery with a minimum of 180 minutes reserve capacity.
