Think of it as a measure of how much 24V lifepo4 battery time your trolling motor battery will give you on the water. Max amp draw shows how much power your trolling motor needs when it’s running at full speed. Specifically, a trolling motor battery with more amp-hours than your motor’s max amp draw. Also listed as dual-purpose batteries, marine AGM batteries such as the 31M-AGM can crank engines and drain deeply on a trolling motor.

 

With so many options on the market, choosing the best trolling motor battery can be daunting. But don’t worry, we’ve put together this guide to help you navigate the world of marine batteries. After 15 hours of research, I’ve confidently sifted through numerous options and come up with this list.

 

What Is The Best Battery For A Minn Kota Trolling Motor?

 

A dual-purpose battery is also more prone to overheating, which is not an ideal option. It is recommended to use a starting battery and deep cycle battery. Still, the dual-purpose batteries work well for short trips and are maintained properly. Other than that, there are some deep-cycle batteries that one can use to start an engine. A deep cycle battery is built to withstand many discharges and recharges, while the dual-purpose battery is not. Dual-purpose batteries cannot withstand well to total discharges and recharges.

 

Trolling Motor Batteries

 

It’s large enough to power trolling motors all day, delivering the thrust you need to fish hard. Trolling motors with 30 pounds of thrust are often found on smaller boats like kayaks and canoes. The following chart shows the run times at various speeds with different battery sizes. They will degrade over time and not put out as much power in the latter years.

 

For instance, if your motor draws 25Ah then the battery will still offer enough charge for around four hours – perfect for most fishing trips on the water. The performance is even better when the motor and boat are smaller, so it’s a fine choice for many types of fishing scenarios. You may want to pick a deep-cycle trolling motor battery with more than twice the amp-hours. Batteries with that kind of power often weigh a lot more, which can wind up taxing your motor more than a lighter battery that offers half the power. Another battery spec you may find on a trolling motor battery is called reserve capacity.

 

However, a more powerful trolling motor for heavier boats may require 24 Volts, so you’ll need two 12V batteries in that case. The fact you can get several hours at top speeds showcases just how impressive this battery is – smaller batteries just don’t offer anywhere near the same run time at top speeds. Take things down a notch and expect the battery life to last even longer, giving anywhere between 6-8 hours depending on the motor draw and water conditions. Even with this, expect a good bit of charge to be left, as the battery will struggle to completely discharge unless used all day at high speeds.

 

Below, we’ll get into the specifics of each, making your decision easier. As mentioned earlier, I brought this motor out to sea for 8 hours straight. Then, once I got home and put the battery on charge, it was still well above 90% power.

 

Customers find the battery performs well with 30lb Minn Kota trolling motors and lasts all summer, with one customer reporting it runs for 8 miles on a single charge. They appreciate its compact size, particularly for small boats and kayaks, and its lightweight design that makes it easy to carry. Customers consider it good value for money and praise its power, with one noting it provides plenty of power for the trolling motor. They find it easy to use, with one mentioning it’s particularly convenient for their Scadden Predator. Deep-cycle batteries are designed to provide continuous power over extended periods, making them ideal for powering trolling motors and supporting marine equipment.

 

The power centre features a charge indicator letting you know the current charge of the battery at any given time. The power centre is lightweight and compact enough for easy use on the smallest of boats and can fit size 24 and size 27 batteries in it. The case makes it easy to transport from location to location and it is surprisingly resilient considering how little it actually weighs and helps keep the batter safe. Each model has its’ own short review, and some even have a longer, full review as well.

 

Getting it right ultimately means more fishing, less hassle and years of performance. Here’s our take on the best trolling motor batteries, no matter the need or circumstance. Whether you fish freshwater or salt, inshore or off, or are powered by paddle or engine, trolling motors open many doors. Pairing your trolling motor with the right battery is the first step to unlocking these benefits. Everyone is very pleased with the quality of this battery, and they say the life cycle is great, the speed of charge is excellent, and the ease of use is perfect.

 

For larger boats the next size up can provide sufficient power output should the 240 model not suffice. At half the price, this battery is a strong alternative to the Optima battery. From the most favored battery manufacturing company in the US, Interstate, one can expect the best performance. This model is a 12-volt trolling motor battery with a 35 Amp hour. The compact nature of the DCM0035 makes it an ideal choice for smaller vessels in need of consistent and reliable power. The grid design is computer-generated which is why it can provide optimum high-power density.

 

Marine batteries may also be considered to power a trolling motor. Often times they are less expensive than the leading trolling battery brands or any trolling motor battery for that matter. Trolling motor batteries are specifically designed for prolonged, harsh activity.

 

Since AGM batteries are fully sealed, they can be purchased online, which will be the focus of this guide. Reserve capacity is another important factor when choosing a trolling motor battery. This capacity is the amount of time a fully charged battery can last until its voltage starts going down.

 

Lithium batteries offer significant benefits that are hard to ignore. Some makers may ask you how your batteries have been charged and used, which could make your claim problematic. Maintenance is straightforward, as a built-in BMS usually takes care of your battery’s health. Power Queen 12V 50Ah offers over 4000 cycles, which is more than ten years of typical use. For example, a Minn Kota Terrova 55 has a maximum amp draw of 50A.
