Spend More Time Fishing, Less On Kayak Battery Angst

Whether you’re zipping around your favorite reservoir for bass or crappie, stalking trout in clear streams, or cruising the lake for your next trophy catfish, a good kayak fishing battery usually means one critical thing — more fish. Why?

Because you can cover more water, and consistently with a trolling motor. You can see the fish around you with your fish finder, and make a beeline to the best fishing holes with your navigator. If you’re looking to take your angling game to the next level, and don’t want to buy a new boat, consider powering your kayak with a lithium battery setup.

Our Ionic Lithium Ion batteries are high quality, affordable and will fit well in your kayak, giving you that extra boost of power you’re looking for. You can power your trolling motor, a fish finder, or even a navigation system. Cover more water, catch more fish!

How to Choose Your Kayak Battery

So you want to power your kayak? No problem. We have a wide selection of lithium batteries best suited for kayaks.

But which one do you pick? Well, it all depends on what you want to power.

To start, let’s talk about your amperage hour rating or “Ah.” This rating refers to a battery's storage capacity, which helps dictate how long the battery will last; the higher the rating, the more storage capacity your battery will have. However, higher amps also mean a larger, heavier battery. So the 12v 50Ah battery will hold the longest charge, but it's also the heaviest. Ultimately, choosing the right battery boils down to what you need to power, and how long you want to use it.

For your favorite gadgets, such as your fish finder or a GPS, you don’t need a ton of power so the smaller batteries such as the 12v 9Ah or the 12v 12Ah are your best bet for smaller screen fish finders. Lightweight and able to perform. If you’re wanting to power multiple fishing accessories, you might opt for the 12v 20Ah, to give you that added boost.

For your kayak's trolling motor, you’re going to want a battery that has more capacity. Most kayakers will be looking for a trolling motor with 30 to 55 lbs of thrust, so you’re probably going to need the 12v 30Ah battery or 12v 50Ah.

If you have a lot to power, it’s good to remember that you also have the option to run batteries in parallel (parallel adds battery capacity, run time). In fact, you can go up to four in series with any of our 12v batteries to run 12V, 24V, 36V or 48V systems. So if you need more than one, that’s no problem either.

Now that we've covered how to choose your kayak battery, let's talk about how to use it.

The Lithium Kayak Battery Advantage

Bluetooth Technology

Our Ionic Lithium batteries are equipped with cutting edge technology. Because they’re bluetooth equipped, you’ll know the status of your battery in real time. All of the guesswork is eliminated with a few taps on your smartphone. You’ll know how much battery is left, and also how long it’ll take to get your battery back to fully charged.

Extended Warranty

We believe in the reliability and longevity of our batteries. That’s why we’re not afraid to put our money where our mouth is. Your battery comes with a 11 Year Battery Warranty to give you peace of mind with your purchase.

Plug & Play

Place your battery where you want it, plug it in, and you’re ready to roll. It’s as easy as that. And remember you have the freedom to run our batteries in parallel, increasing your voltage but keeping your capacity the same.

Smaller & Lighter

Many batteries can easily weigh down your kayak. Our kayak batteries are smaller and lighter, so they fit better and do their job without slowing your kayak.

More Energy Efficient

Ionic Lithium Deep Cycle batteries have the greatest size/power ratio out there; better than any other deep cycle battery you can find.

One of the perks of lithium is the self-discharge rate is way better than lead acid. With lead acid batteries you’re looking at a self-discharge rate of 30% per month. Lithium, on the other hand, hovers around only 1-3%. Lastly, our lithium-ion batteries have a usable capacity of 99% of stored capacity vs. 50-60% for traditional lead acid.

More Reliable

Our Ionic lithium batteries have 2-4x the service life (3,000 - 5,000 cycles) of other batteries, and on average last for a whopping 10 years. Lithium batteries can also handle a wide range of temperatures. If you’re looking for a high quality product that’s going to be reliable in the long run, look no further.

World Class Safety

Safety while on the water is essential. With top of the line safety features and an internal microprocessor, your battery monitors voltage, internal temperature, and currents. Lithium is also non-toxic and safe for the environment.

We'll get you up and running in no time

With Ionic Deep Cycle Lithium Marine Batteries powering your kayak, you'll be able to spend more time on the water doing the things you love. No more worrying about whether your lead-acid battery is charged and ready to go. No more stressing over what level the charge is at. Our lithium kayak batteries are fast, efficient, lightweight, and easy to use.

The Lithium Motorized Kayak Investment

Powered with our Deep Cycle Lithium Batteries, you can take your kayak on new adventures. Sure, it’s still fun to get out the old paddle every now and then. But who doesn’t want to fish 5x-10x more fishing holes and catch a lot more fish as a result? Plus, trolling your lake is much faster (and easier) too.

Also, you can use your Ionic lithium batteries to power your favorite fish-finding and nav gear. Just power up your fish finder, and there’s no place for the fish to hide. So, your lithium kayak fishing batteries give you the ability to:

  • Cover more water with a trolling motor

  • Catch more fish with the help of a kayak friendly fish finder, like the Humminbird 409690-1 PiranhaMax or Raymarine Dragonfly 7 Pro

  • Keep your smartphone charged with a waterproof battery box like the Yak power pack

  • And many other things

But is it all worth the investment? Well, on the front end, lithium costs more than a lead acid battery. But you save a lot long term. And because they’re no-maintenance and less expensive long term, you’ll have less to stress about too. Our lithium batteries keep your kayak on the water longer, and keep you fishing longer. And on top of that, they give you peace of mind. That’s why our lithium batteries are a top quality choice and wise investment.
