In contrast, boat-starting batteries are utilized for ignition purposes. Marine batteries are crucial for engine ignition and providing sufficient power to operate machinery and devices on board. To make an informed decision about which trolling motor battery to select, it’s important to grasp the various types of batteries available.

What is a deep cycle trolling motor battery?

Most trolling motor batteries are deep cycle batteries, intended to provide sustained energy over extended periods, ideal for leisurely trolling during fishing trips. Deep cycle batteries discharge electricity moderately and consistently to ensure prolonged motor operation.

Given the necessity for uninterrupted power, opting for a dual-purpose or deep cycle trolling motor battery is advisable. Distinct from car engine starter batteries, these options deliver reliable power to sustain engine functionality. A dual-purpose battery offers the added benefit of facilitating engine ignition while supporting prolonged operation. True to their name, dual-purpose batteries serve dual functions efficiently.

Conversely, deep cycle batteries are tailored for consistent power delivery to trolling motors, optimizing performance in such applications. Depending on your requirements, a dual-purpose battery offers versatility, combining the benefits of both types. For those prioritizing longevity in trolling motor performance, deep cycle batteries are the preferred choice.

What to Look for in the Best Trolling Battery

The ideal trolling battery combines reliability with the ability to endure multiple charge cycles without faltering. It’s a battery whose power output remains steadfast despite its weight, refusing to buckle under pressure and fail when you need it most. Moreover, a high-quality battery maintains consistent performance over the years.

For these reasons, lithium batteries have emerged as the preferred choice for trolling motors today. However, not all lithium batteries are created equal. Here are some key considerations when selecting yours:

Choosing a Long-lasting Lithium Battery

The first question to address is: Why opt for lithium? Typically, consumers are presented with three battery options for their trolling motor: wet cell batteries, advanced glass mat (AGM) batteries, and lithium batteries. Each option has its own advantages and disadvantages:

Wet cell batteries are affordable and have stood the test of time but require regular maintenance. AGM batteries offer greater power output without maintenance requirements, but they come at a higher price and heavier weight. In contrast, lithium batteries are lightweight, maintenance-free, and offer comparable power to AGM batteries, making them an attractive option alongside wet cell batteries.

Additionally, lithium batteries boast long-lasting performance, with some brands claiming a lifespan of up to a decade before replacement is necessary. While lithium batteries may have a higher upfront cost, they prove to be a worthwhile investment, leading to significant long-term savings as replacements are seldom required.

However, it’s crucial to verify compatibility before purchasing, as not all trolling motors are designed to work with lithium batteries. Be sure to check compatibility to avoid any compatibility issues.

Battery Size Matters

The size of your trolling motor and the size of the boat it’s paired with matters. When shopping for lithium batteries for trolling motors, you’ll need to consider amperage and voltage. The larger the trolling motor, the higher capacity you’ll need in its battery. For optimal performance, look at your manual or speak to the manufacturer for guidance.

What to Look for in Your Lithium Trolling Battery

The first consideration is the requirements of your trolling motor. Typically, trolling motors operate on three voltages: 12v, 24v, or 36v. You’ll need a battery with matching voltage or multiple batteries connected to meet the motor’s voltage needs.

When using two batteries, ensure they are both new. Avoid mixing old and new batteries, as well as different types when connecting them.

Also, keep in mind the maximum amp-draw of your motor, which should always be lower than the battery’s max amp-draw (also known as continuous discharge rate). Your motor has a maximum power demand from the battery, and the battery can only deliver a certain amount of power at a time. If the battery’s max amp draw is too low, you won’t get enough power to run your trolling motor at full strength.

Once you know your trolling motor’s requirements, focus your search on weight, price, and amp-hours.

Amp-Hours

Amp-hours (Ah) indicate the total use your battery can provide on one charge, depending on the motor’s amp-draw. For instance, with a 100 Ah battery and a motor drawing 25 amps, you’ll get about four hours of continuous use at top speed. Typically, if you plan to fish all day, aim for a battery with double the capacity of your motor’s max draw. For a motor drawing 25 amps, a 50 Ah battery should suffice. For shorter outings, a battery with the same amp hours as your motor’s max amp draw should be adequate.

Weight

Weight isn’t significantly different with lithium batteries, as they are generally lighter than other types. However, some models are lighter than others, and you might consider paying more for that advantage.

Cost

Cost is often the deciding factor when choosing batteries and can be a barrier for many buyers. Lithium batteries are more expensive compared to other options. Quality usually correlates with cost, with factors like higher voltage and amp-hours or reduced weight increasing the price of a lithium battery.

The Best Trolling Battery Brings the Best Fishing

These factors of amp-hours, weight, and cost are likely to be your most significant considerations when choosing your lithium trolling battery. The last thing to keep in mind, however, is warranty and lifetime battery life which can vary drastically depending on the brand.

Determining your budget and comparing that to your needs on the water is vital to selecting the best trolling battery for you. Once you decide both, the right trolling battery isn’t far out of reach.

Other Perks Of Going With Lithium

Unlike traditional batteries, a lithium trolling motor battery can discharge to zero and recharge safely. Its design ensures secure draining and charging processes. Thanks to a sophisticated Battery Management System (BMS), concerns about overcharging or undercharging are alleviated, preventing any damage to sensitive components that might affect battery performance.
