Marine Trolling Motor Batteries

Trolling motor batteries are the silent powerhouse behind your boating adventures, providing the essential energy needed to power electric trolling motors. These specialized batteries are designed to deliver reliable and consistent performance, ensuring your trolling motor runs smoothly while extending your time on the water. Key points to consider include battery capacity, as it determines how long you can use your motor before recharging, and voltage, which influences the motor’s thrust. It’s crucial to select a battery with sufficient capacity and voltage to match your trolling motor’s requirements. Deep-cycle trolling motor batteries are the preferred choice, designed to handle frequent discharging and recharging without compromising longevity. Investing in a high-quality trolling motor battery ensures efficiency, durability, and uninterrupted hours of leisurely or productive boating.

The most of modern boats today use electrical energy. You can also use rechargeable trolling motor batteries for convenience. Thanks to advanced technology, high output trolling motor batteries for canoes, kayaks, or fishing boats with relatively light weight in a compact design are now available. High output rechargeable batteries gives the boating industry a more echo friendly alternative to noisy and high emission emitting diesel or gasoline engines while simultaneously operating quietly.

A great advantage of quiet electric motors is for fishing and hunting because an electric motor does not generate harsh combustion acoustic vibrations, but rather a smooth and nearly silent hum from its armature, which allows any outdoors enthusiast to travel without startling potential game in or out of the water. But to keep your electric motors operating for the longest time possible, and get the great distance, you need reliable high output batteries. We have selected a number of batteries which feature all these characteristics for optimal electric motor performance, and reliability. These are water proof and have a completely sealed housing so that they can be used in a wide range of weather conditions.

Additionally, AGM; absorbed glass mat, technology allows the battery’s internal cells to distribute electrons evenly, and can do so in any mounting position: even completely upside down, and with absolutely no operator maintenance. High performance, reliability, and a long service life characterize all of the batteries on our website. For the best choice in leading edge technology and maintenance free operation, AGM batteries are the top tier choice for trolling motors, as well as for any other mobile heavy equipment application.

Batteries Types

It is very important to relate to its type when choosing. This determines the application, capacity, method of charging, maximum loads and current output, and other parameters. There are many different types of trolling motor batteries today:

  • lead-acid;
  • gel electrolite;
  • lithium, etc.

But the acid-lead ones are still the most common. They account for about 80% of the total number of batteries used. It is fair to say that different technologies can also be used to produce such batteries. For you, we have chosen batteries which are produced using the latest technology, the so-called AGM batteries. This technology increases the battery life significantly and also allows you to distribute the liquid (electrolyte) within the battery evenly, making it more efficient. Such batteries can be placed at any angle, even upside down. They also have an increased capacity.
In addition, there are SLA trolling motor batteries. These are traditional lead-acid batteries with minor differences. And the most important difference is the presence of a valve that can relieve the overpressure that can occur within the battery as a result of overheating and overloading. This technology is used in all sealed lead-acid batteries. We have selected for you only the best, reliable and safest batteries with longer service life. Check out the options and make the right choice.

Marine Batteries Voltage is an important parameter

Another important parameter for any battery is its voltage. This also affects which equipment can be connected to the battery. It is important here that the battery output voltage coincides with the equipment requirements. We have selected 12 V voltage batteries for you. They have a wide range of applications, however, these batteries are most often used to troll electric motors on inflatable boats and kayaks. Such batteries are relatively small in mass and compact in size, so they can be placed even in small rubber boats. Remember, the first thing to look at when choosing is the voltage the battery can deliver.

Capacity of Battery for Trolling Motor as one of the most important factors

Battery capacity is also one of the most important factors. Naturally, this does not affect the application as much as it does, but the capacity determines how long a particular device is powered by the battery. And there’s always a clear rule – the bigger the capacity, the longer the battery holds the charge and the longer the equipment can be powered. However, you need to know that, as the capacity increases, the battery size and its weight also increase. It is thus important to select a capacity that is sufficient and that at the same time you are satisfied with the battery weight and size. We have therefore selected several trolling motor battery models for you, with various specifications, capacity, size, and weight. Explore the proposed model and choose the best one to meet your requirements.

Battery’s Moisture Protection

Most batteries are not moisture-protected and are therefore fitted in the safest places. However, if the battery is used in boats to power the trolling motor, conventional batteries will not be suitable. We have picked up for you models of moisture-proof accumulators, which can be used with electric motors on boats and kayaks. Furthermore, these batteries are ideal for use both on land transport and on different equipment. Explore the options and choose the most suitable universal trolling motor battery with a wide range of applications.

Types of Connection Terminals

There are many different types of connection terminals today:

  • screws;
  • clamp terminals;
  • lug terminals, etc.

We have selected different battery types for you with different terminal types, from terminal screws to clamp terminals. It stands to mention that clamp terminals are universal as they themselves are designed for clamping wires. You do not need to select the appropriate diameter lugs. We have picked up for you several types of batteries with different types of terminals, from clamping screws to terminals for clamps. Look at the proposed options and choose the most suitable type of terminals.

Marine Battery’s Weight and Aimensions

One of the important parameters when choosing a battery is its dimensions and weight. It is very important that weight and dimensions are minimized as much as possible so that when placed in inflatable boats or kayaks, the battery doesn’t create further problems. Moreover, when installing and carrying the battery, the weight and dimensions affect the convenience. Modern technology can significantly increase the trolling motor battery’s efficiency and capacity without increasing weight and dimensions. We picked up such models of batteries, which are relatively small in weight and size. Check out the options and choose the model that best meets your requirements.

How to Choose Trolling Motor Battery

In this section we’ll be talking about selecting the correct battery for use with your MinnKota electric fishing motor or a motor by another company. First of all, we have a couple of different choices that we can actually choose from:

  • gel cell type battery,
  • AGM type battery,
  • flooded lead-acid battery.

Well, how do those three types differ?

Main difference between gel cell, AGM and flooded lead-acid batteries

First of all, in the gel cell, the liquid electrolyte is jelled by adding silica to the electrolyte so that it becomes immobile.

In the case of the AGM battery, the only electrolyte that’s held in that battery cell is the electrolyte that’s actually held in suspension in a fiberglass matting material that’s actually positioned between the cell plates. In the case of the AGM battery, the only electrolyte that’s in the individual cells is that that’s held in suspension in the fiberglass matting material that’s actually between the cell plates. So in the process of making an AGM battery, they fill each individual cell with the acid and then pour off the excess. So the only acid that’s there… electrolyte that is actually there is that that’s actually held in between the plates by that fiberglass matting material.

In the case of the flooded lead acid battery like this, we can actually pop the cell caps off and monitor the electrolyte level and add distilled water if necessary, if the electrolyte level drops below a certain point. And so that’s actually one of the benefits of having flooded lead acid, is that you can do some battery maintenance. other types are completely sealed and so there is no chance of adding electrolyte to either a gel cell or an AGM type battery.

One of the other things about the deep-cycle battery is that it’s heavy. individual cell plate construction is such that the battery is built to withstand a greater number of discharge recharge cycles. So this happens to be a Group 29 size battery with an amp hour rating of about 110 amp hours. And that’s the other thing that we really want to look for when choosing a battery for use with your fishing trolling motor.

The AMP hour rating can be liken to the gallons of gas that you have in your fuel tank. more gallons of gas you have, the farther that you can go. In this case, the more amp hours that you have, the longer that electric motor will run. So always look at that. Be sure to take a good close look at the amp hour rating. Oftentimes when you go to look at purchasing a battery, you can spend a lot of money on batteries, but oftentimes those batteries don’t have the highest amp hour rating.

Marine Starting Battery

The other type of battery that we have up here on the bench top is an example of a marine starting battery. This one happens to be a Group 24 battery and it is designed to start an engine. What does that mean? Well, it simply means that the individual cells are constructed with a higher number of individual plates stacked up in kind of a sandwich style so that this battery can deliver high amperage for a relatively short period of time. Where our deep-cycle battery is designed to deliver relatively low amperage for a longer period of time. So in this case, more plates, thinner plates. It’s designed to deliver a lot of power to start an engine and then immediately as soon as the engine is started, this battery is being recharged by the engine driven alternator.

So two different types, but the thing to remember when choosing a battery for electric motor, always buy a deep-cycle battery. Look at the amp hour rating, and the amp hour rating, the higher the better. And you’ll have a battery that’s going to perform up to your expectations and the motor will certainly perform much better as well.

  1. I bought the Vmax MR127 motor battery and there was no information about its dimension. Now I have a brochure and would like to report the dimension is 7x9x12 inches. I hope it’ll be useful for someone.

  2. Victor H. says:

    12 volt MightyMax battery. Pleased with my purchase for my Minn Kota 50 Endura Max electric motor. About six hours out yesterday on the river trolling all the time and almost no downtime where we didn’t use the motor. Great work of the battery. I’m very impressed. Only one con — it’s very heavy but worth it!

  3. fourth battery on this list, not entirely sure what the real and set name is for it. But, it has lasted me quite a while with my kayak. I used to have problems with overheating in the battery of my kayak but not anymore! This has been a godsend because of the hassle I have put in with other battery brands.

  4. I just recently got the Mighty Max Battery and I think it is holding up very well. It was pretty easy to hook up and I’m glad it has a one year warranty because I have had bad luck with things breaking on me within the year. Only had to go and buy the mounting equipment but that wasn’t too bad.

  5. Marine Trolling Motor Battery by Newport Vessels. A maintenance-free battery is super convenient. This one’s a 12 volts battery, needs to be charged once before installation.
