Trolling Motor Battery: What We Should Know

Author: Polinovel | July 6, 2022

Overview

When it comes to choosing a trolling motor battery, there are some things we should take into consideration. Let’s take a closer look at these things.

Part 1. An Introduction to Trolling Motor Batteries

Trolling motor batteries are designed to deliver consistent and steady power over a long period of time to keep the motor running.

To better understand what trolling motor battery is, we need to know the different types of batteries used in trolling motor.

Part 2. Different Types of Batteries for Trolling Motors

Lead Acid Wet-Cell and AGM

Wet cell means that the cells in the battery are submerged in electrolyte fluid, a mixture of sulfuric acid and water. The water level will drop if the battery is overcharged frequently. So it is necessary to check the battery before we use it. We should add distilled water to maintain the appropriate water level and prevent damage.

AGM (Absorbed Glass Mat) batteries are completely sealed. Therefore, we don’t need to worry about spills. AGM batteries are more expensive than wet cell batteries and do not require much maintenance. What’s more, AGM batteries have a longer lifespan. They can last up to 3-4 years.

LiFePO4 Battery

Lithium iron phosphate batteries, also known as LiFePO4 batteries and LFP batteries, are growing in popularity in the market for their great advantages. LFP batteries are much lighter in weight compared to traditional lead-acid batteries.

What’s more, LFP batteries have a significantly longer life and a higher depth of discharge. They can last up to 10 years and require zero maintenance, thus saving us much money in the long term.

Part 3. What Specifications Should We Look for?

We should also learn the battery specifications to know how to choose a suitable trolling motor battery.

The first one is the amp hour rating, which indicates how much power the battery has, and how long we can use the battery. This is one of the most critical specifications to know when selecting a trolling motor battery. A 150 amp hour rated battery can deliver 150 amp hours of current to the trolling motor. If a motor is running at low speed and pulling 5 amps, the battery can last around 20 hours.

Additionally, we should know the voltage. We should check our power system to see if it needs more voltage, such as 24 volts or 36 volts.

Summary

We have learned that there are different battery types and specifications while considering a trolling motor battery. When it comes to battery types, we suggest using LiFePO4 batteries for their unparalleled advantages such as having a long lifespan, requiring no maintenance, etc.
