Looking for the Best Trolling Motor Batteries? Here's a Guide!


Trolling motor battery - Not exactly a super sexy product in the eyes of many folks, but hey what do they know?

What they fail to understand though, is the importance to choose the correct one -as you'll only look pretty stupid when you're stuck out in your boat or fishing kayak when your battery is as flat as a pancake and your engine's not working!

If you've invested heavily on the top of the range kayak trolling motor, it's only correct that you buy the best possible battery to go with it. What we're going to do is help you choose the best trolling motor battery as per your requirements. We will take into account several factors such as battery size, capacity, the power output to name a few.

Do you require a 12-volt, 24-volt or 36-volt variant?

How much thrust do you require for your craft? 50lbs or 100lbs?

Which specific type of deep-cycle 12-volt batteries are best suited for you- SLA (Sealed Lead Acid) or AGM (Absorbed Glass Matt)?

Quite often some of these questions can be answered by common sense. For example, if you're going out with 5 friends then a 50lbs thrust motor isn't going to be powerful enough (the weight of your craft needs to be factored in here naturally) to get you out to the sweet fishing spot and back several hours later.

What sort of battery charge does the product need to have? If you're constantly having to recharge, then maybe it's time to consider replacing the battery.

A spill-proof design trolling battery is important. If the water gets a little bit choppy you want to ensure that your battery is going to stay in place, keep upright and not leak or spill anywhere.
Earlier, I mentioned about spending and getting the better product. Why would someone splash out (pun intended) on one of the top Minn Kota trolling motors, because you know how awesome a product these are, only to then cut corners and but the cheapest battery for it?

We recommend choosing the Absorbent Glass Mat technology products where possible.

Yes, it's a personal preference but we find that this technology extracts every last bit of power and delivers it to you for optimum performance.



What Is a Boat Trolling Motor?

Trolling motor battery is an essential piece of kit for anyone serious about kayak fishing. If the first thing that pops into your mind when hearing the words “best trolling motor battery” is a comment thread on YouTube or Reddit, then you’re probably spending too much time on the Internet, and too little time fishing and kayaking.

On a more serious note, if you know the basics of boating, feel free to skip this section and get straight to the Trolling Motor Battery Reviews; if, however, you wish to know more about the topic, stick around and read through this brief guide.

First thing’s first – what is a trolling motor?

In a nutshell, it’s a motor that sits either at the bow or stern of an angling boat. It consists of an electric motor, obviously, as well as props and controls. Pretty straightforward, right? Here’s where it gets interesting – a gas-powered motor may also be referred to as a kayak trolling motor, provided you’re using it for trolling and it’s not the primary source of propulsion. Still, you’ll want something that makes as little fumes (ideally none) and noise as possible, and this is where electric motors come in handy.

Painting with a broad brush, all of the trolling motors can be divided into freshwater and saltwater- the difference is pretty much obvious – saltwater motors have to be better protected from rust. Granted, you could just as easily use a freshwater motor in salt water, but there are some protective measures you need to take; one of them being to regularly wash the motor after every use and thoroughly at that. Keep in mind that most of the time the only things getting wet are the lower unit and the shaft, so if you don’t actually live on the coast and troll exclusively in salt water, you can get by with a freshwater trolling motor. One thing to keep that in mind is that if you do use a freshwater motor in salt water, the warranty will be void.

What To Look for In A Trolling Motor Battery?

A kayak with a trolling motor is a great way to spend the weekend, provided you know what to look for when getting the components. Before moving onto the best trolling motor battery, we’ll need to get to know trolling motors in a bit more detail first.

The single most important feature you’ll need to look out for when getting a trolling motor is its thrust, or, in simpler words, its strength. In general, a 50 lb. thrust trolling motor should be able to push up to a 17-foot long boat, with about 2,000 lbs. of load; give or take a couple of pounds. If you mean to haul additional gear, you’ll obviously need a bigger boat and, consequently, a more potent motor. A 100 lb. trolling motor is pretty much as potent as you’ll get without switching to gas-powered engines.

On a similar note, you’ll need to decide whether to get the 12-volt, 24-volt or 36-volt variant: and here’s where we get to the batteries.

In a nutshell, the thrust is predicated by the voltage, so, painting with a broad brush, we can make the following correlation – a 12-volt creates up to 60 pounds of thrust, a 24-volt motor generates up to 100 pounds. If you need more than that, you’ll have to get a 36-volt motor. This system is designed so as to take advantage of the 12-volt deep cycle batteries, with voltages higher than 12 requiring the batteries be connected in series.


Buyers Guide: Best Trolling Motor Batteries

To save you the trouble, we decided to do the legwork and make a list of the best trolling motor batteries, and throw in a bit of variety in there, so there’s something for everyone.

So that you may reach an informed decision, we briefly clarify what’s on the table.

For a start, there are basically two specific distinct of deep-cycle 12-volt batteries – SLA (Sealed Lead Acid) and AGM (Absorbed Glass Matt). The main difference between the two is pretty much the lifespan and price tag. The former is much more common (and cheaper), and should survive for about two years, give or take a couple of months. They usually require some maintenance though, which you’ll rarely find a need for in the higher-end SLA’s.

Conversely, the AGM batteries are a bit less common, and they come with a matching price tag. They’re definitely an option for folks working on a tight budget. They also have longer lifespans (about twice as long on average), and are invariably maintenance-free.
