Types of Lithium Marine Batteries and Their Purpose
Most bass boats require two basic types of 12 volt batteries. One is the cranking, or starting battery type. It's used to start the main engine. The other type is the deep cycle battery. It's used to power the trolling motor and other accessories. Some batteries do both (to some extent anyway).
Cranking
Batteries
Most bass boats require two basic types of 12 volt batteries. The cranking, or starting battery type is used to start the main engine. And the deep cycle battery type is used to power the trolling motor and other accessories. Some batteries do both, to some extent anyway.
Deep Cycle
Batteries
Deep cycle batteries, unlike cranking batteries, are designed to release power slowly. They can be drained and recharged multiple times over their lifespan. While both are important, deep cycle batteries are the ones that you depend on for most of your navigation and power. These batteries are responsible for the trolling motor and other battery powered appliances on your boat. (Like your audio system, fish finder, and GPS.)
dual purpose
Batteries
Some boats don’t have room for more than one battery, so they need a dual-purpose battery. While dual-purpose batteries are available on the market, many boaters don’t choose them. Because they aren’t as powerful as a cranking battery. They also don’t last as long as a deep-cycle battery. Instead, most professionals opt for two separate batteries.
The 4 Boat Battery Technology Types
There’s four different technologies you can choose from. There’s the lead-acid battery, gel batteries, AGM batteries (Absorbed Glass Mat), and lithium batteries. Here’s the pros and cons of each:
lead-acid Batteries
These batteries are inexpensive short term, and can be recharged multiple times. However, they also break easily, and have to be maintained constantly to avoid problems. Checking and refilling the water level every couple of weeks is extremely important or you risk damaging your battery. In addition, leakage can be devastating to marine environments, and brings up a lot of safety concerns.
AGM Batteries
These batteries don’t require a lot of maintenance, and they rarely leak. However, the upfront cost is expensive, and if they do need maintenance from overuse, it’s difficult to reach the internal components. Chances are, you’ll just have to purchase a whole new battery instead. They also require more battery charges as they can only be discharged to 50% whereas an Ionic lithium battery can be drained to full capacity.
Gel Batteries
Gel batteries are popular because they don’t require a recharge very often, and they can be stored for a long time without losing their life. Their drawback is how expensive they are compared to other batteries with the same RC and MCA. Charging a gel battery can also be an annoying process. The charge cycle can be slow, and you have to be present to disconnect the battery charger as soon as it’s complete. Failure to do so can cause irreversible damage, requiring a new battery and a whole lot of money down the drain.
Lithium Batteries
Comparing a lithium battery to the rest is like comparing an iPhone to a flip phone. Both options work, but one clearly has better reliability, function, and design. Lithium batteries come with a cost, but they last longer, weigh much less, are maintenance free, and aren’t toxic to the environment. And if we’re talking Ionic batteries? They're currently the only lithium deep cycle batteries on the market with bluetooth technology. This takes away any guesswork or worry. With our lithium batteries (unlike others) you’ll know precisely how much charge is left.
The good news is, lithium batteries not only maintain their charge for longer, but if you choose Ionic they’re also bluetooth equipped. With a few taps on your cell phone, you’ll know whether your batteries are good to go or not. It’s that easy. Plus, every one of our batteries has a built in BMS to keep it from overcharging.
Our lithium deep cycle marine batteries provide a longer battery life, with less recharging and no maintenance. No more lake days spent at home, less stress, more time on the water.
Built in Cold Weather Protection
Ionic deep cycle lithium batteries have built in cold weather protection - Does not take a charge if temperatures are below -4C or 24F in our case. Some variations with part tolerances.
Our Ionic heater deep cycle batteries warm up the battery to enable a charger once battery is warmed up.

Consistent Output
Most batteries on the market will not put out as much amperage once it reaches 50% battery life. This means that while you still may have 50% of your battery left, the amperage isn’t as strong, so some of your accessories may stop working.
Comparatively, lithium marine batteries continue to put out the same amount of amperage even once they have reached below 50% battery life. Not only this, but lithium batteries can be fully drained before they need to be recharged.
Maintain Charge
If you remember from the previous section, gel batteries are usually bought because of their ability to maintain their charge even if they are not being used. Well, Ionic lithium marine batteries can do the same thing.
Unlike many other types of batteries, lithium marine batteries can maintain their charge for years. Even if they’re put into a storage shed and not used or kept charging.
Lightweight
Most batteries weigh down your boat and can be difficult to move around if they need maintenance. Ionic deep cycle lithium marine batteries are lightweight and compact, so they can fit onto almost any boat, and get the job done without weighing down your boat. You’ll spend less on gas and be able to navigate more.
Status Monitoring
Not only do lithium marine batteries charge much quicker than a lead-acid one, but our Ionic batteries are also bluetooth equipped. No need to guess if your battery needs to be recharged or not, you can see exactly how much charge is left, and how long the charge cycle will take. All with a couple of taps on your phone with the Ionic iOS or Android app.
Long Lasting
We’ve all heard the saying “you get what you pay for,” and there’s generally a lot of truth to that. With an Ionic lithium marine battery you’re going to pay more up-front, but that cost will save you a lot in the long run. Here’s how.
Compared to a lead-acid battery, a lithium marine battery usually lasts 2-4x longer (and up to 10x longer). A lead-acid battery is usually able to be recharged about 300 to 400 times. If you’re using it every day, that means it will last you around a year.
In comparison, our Ionic deep cycle lithium marine batteries are rated to last 5000 cycles, which means they can be recharged 5000 times. That’s nearly 14 years of usage, if you’re using it every day. So while the lithium marine battery is more expensive initially, the amount you’re actually going to spend is much less in the long run.
Environmentally Friendly
Lead-acid batteries are known for their leakage. They can leak battery acid into the water and onto your boat if you are not careful with their upkeep. Our lithium batteries are leak-free and toxic-free. You can even recycle them.
In addition, our Ionic lithium marine batteries do not require any sort of ventilation, since they don’t have any toxic chemicals in them. Therefore, you can store them anywhere - even inside.

Maintenance Free
Lead-acid batteries require constant maintenance to keep it from being damaged. They constantly need to be refilled with water, corrosion removal, and electrolyte replacement. Want to get on the water and enjoy yourself without worrying about non-stop maintenance? Lithium is your ticket, as they require exactly zero maintenance. And they'll never overcharge, thanks to their built-in battery management system.
We'll get you up and running in no time
With Ionic deep cycle lithium marine batteries powering your boat, 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 or wondering what level the charge is at. Lithium marine deep cycle batteries are fast, efficient, lightweight, and easy to use.
Typical Lithium Marine Bass Boat Battery Setups
The most common setup we see for bass boats with a 36 volt trolling motor is three 12V 50Ah batteries for the trolling motor and one 12V 125Ah battery for your engine starter and other equipment like a fish finder.
But if simplicity is what you’re after, why not swap out your three 12V trolling motor batteries for one 36V 50Ah battery? You’ll have fewer cables to hook up and less connection points to worry about.
Neither option is better than the other, as there are pros and cons to both. In the end, it’s all about finding what works best for you! Check out the full rundown on one 36V battery vs. three 12V batteries here.
Smaller bass boats can manage with fewer batteries: If you were running a 24 volt trolling motor then you could use two 12V 100Ah batteries for the trolling motor and one 12V 125Ah battery for the engine starter and other onboard equipment.
Here are some more in depth examples based on common questions and setups we see.
36 volt trolling motor and starter battery
Let’s say you need to power a 36V, 112lb thrust trolling motor (max amp draw of 52A). And you’re looking for a lithium battery for starting your 250hp outboard and running two large depth finders as well. Here’s your best options:
For 36V trolling systems, the majority of our customers use our Ionic deep cycle 12V 50Ah lithium marine battery, which provides plenty of reserve energy. But you can also use our 36V 50Ah battery. The choice is yours!
For the starter battery, our bass boat customers (most of which have 200-250hp 4-stroke motors) typically go with our recommended Ionic deep cycle 12V 125Ah lithium marine battery.
24 volt trolling motor and starter battery
Now, let’s say you have a 24V 80lb thrust trolling motor and a 300 Yamaha hpdi. You have 2 batteries for the trolling motor and 2 cranking (perko switch for the cranking). You’re looking for your best possible lithium set up. What do you need?
For your 24 volt trolling systems, we recommend two Ionic 12V 100Ah lithium marine batteries.
For your starter battery, we recommend the Ionic deep cycle 12V 125Ah lithium marine battery.
