What is A Kayak Trolling Motor Battery?
Trolling motors are electric engines attached on the bow, stern, or gunwales of kayaks, that allows you to fish in areas that would otherwise be inaccessible, such as shallow streams or along the shoreline. They are relatively quiet, so they won’t scare away the fish.
Just like a car engine, your trolling motor also needs a source of electricity to do its thing. And that’s where trolling motor batteries come in. It provides a steady source of power, so you can keep your kayak moving at a consistent speed. It is usually relatively easy to install and lightweight, so it won’t add too much weight to your kayak.
One thing I need to point out here is that both deep cycle marine batteries and trolling batteries are the same thing. But that’s not the only potential point of confusion. If you’re interested in deciphering the mysterious numbers and abbreviations found on batteries, read on.
Best Kayak Trolling Motor Battery Buyer’s Guide
There’s a lot of terms thrown about when it comes to batteries, and going out and buying a trolling motor battery willy-nilly without understanding the intricacies of the system is a great way to end up with a battery you can’t use.
Trolling Motor Battery Designs
The first term you’ll need to learn refers to the model and design of the battery. For trolling motor batteries, the most common designs are lead acid wet-cell, AGM, and lithium.
Lead acid wet-cell batteries are among the most common battery designs for trolling motor batteries. These batteries are tough, but inexpensive compared to the other two types. The downside here is that they have a lower lifespan than the other two, and that they aren’t maintenance-free, and that they’re also vulnerable to shocks and vibration. Lead acid wet-cell batteries can also spill, so be wary of this especially if you’re angling in choppy waters.
AGM stands for absorbed glass mat, and these batteries fall under the SLA, or sealed lead acid category. Like their name implies, these batteries are sealed off, meaning that they’re not only maintenance-free, but also spillproof and resistant to vibrations and shocks thanks to their outer shells. It’s not unusual for an AGM battery to last 4 years with the proper care, and thanks to the introduction of lithium batteries, AGM batteries are seeing a slow but steady price drop. However, they’re still more expensive than lead acid wet-cell batteries.
Lithium batteries are the new kids on the block, and anything that lead acid wet-cells and AGMs can do, lithium can do better. With perfect discharge that yields 100% battery power regardless of how charged the battery is, as well as a lightweight design and an incredible lifespan, it’s no surprise that lithium batteries are also the most expensive of the three.
Best Kayak Trolling Motor Battery: Amp Hours
Another important part of buying a trolling motor battery is learning to decipher what amp hours (or Ah) means.
What are Amp Hours in Trolling Motor Batteries?
Without delving too much into the science, amp hours are a measure of electrical output and runtime. A higher amp hour rating means that a battery will perform longer and deliver more power, while the reverse is also true.
Amp hours are important because you don’t want to end up with a battery that’s too weak for your motor. As a general rule of thumb, you should be fine with a 100Ah battery – but you should always double-check your motor to see what conditions it runs best in.
Now that I’ve hopefully demystified most of the terms surrounding batteries and given you the basic knowledge you’ll need to get a good battery, let’s get to my list of the best kayak trolling motor battery products available on the market today.

Just like the VMAX though, this battery has a short 1-year warranty – be sure to have your battery checked before that time is up.
Bottomline: This trolling motor batter uses both clean energy and provides great performance, which are two big check marks for me.
FAQs about the Best Kayak Trolling Motor Battery
What is the best design for a trolling motor battery?
This is a tough one, as it’s more down to personal preference. I will say that I have a preference for AGM batteries – they’re reasonably durable, last a long time with the proper care, and offer solid performance.
Can I mix battery types?
No – and never ever do this. In the best case scenario, this can lead to underperformance. While in the worst case scenario, you can get battery acid leaks.
How many years do trolling motor batteries last?
That depends on the kind of battery, but you’ll most commonly have a lifespan of 2-4 years on average.
What’s the difference between trolling motor batteries and a deep cycle marine battery?
Nothing apart from the name – they’re the same thing.
Why am I not getting all the performance time out of my battery?
A battery’s maximum run time is always determined in controlled, ideal conditions. Apart from this, there are a lot of other variables such as weather, battery condition, and battery age that can affect the actual run time of your battery.
Are there any risks involved with a trolling motor battery?
As long as the battery is handled carefully, you’ll be safe. However, you’ll want to install a trolling circuit breaker in your system. This will prolong the life of both your motor and battery and prevent power overdraw.
Is it safe to overcharge my trolling motor batteries?
While it’s technically safe, overcharging your trolling motor battery will damage it, leading to a decrease in performance.
Is it safe to undercharge my trolling motor batteries?
Undercharging is also technically safe. But this will also decrease performance due to a process called sulfation. This is when sulfate begins to accumulate on the battery’s cell.
Enjoy Your New Kayak Trolling Motor Battery
Whether it’s for a quiet day of fishing or for a new, daring adventure, your new trolling motor batteries will be a reliable companion come what may. Just remember – always treat you equipment with respect and care, and it’ll take care of you.
