The Ionic Lithium Marine Battery Advantage

These batteries have been gaining popularity with professional boaters and anglers because of their long life span, consistent output, and their ability to maintain their charge. Whether you’re a professional or a hobbyist, Lithium is a great option because:

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.

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.

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. If you just 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.

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.

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.

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 Iconic 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.

Types of Lithium Marine Batteries and Their Purpose

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 the other accessories. Some batteries do both, to some extent anyway.

Cranking Batteries

Cranking batteries, also known as Marine Starting batteries, are what start your boat’s engine. They’re designed to deliver a burst of power for a short amount of time. Cranking batteries can be recharged from the engine's alternator or from a 3 or 4 bank charger.

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 Battery

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 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. Though lithium come with a cost, they last longer, weigh much less, are maintenance free, and aren’t toxic to the environment. And if we’re talking about Ionic batteries, keep in mind that they’re currently the only lithium deep cycle battery 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.

Typical Lithium Marine Bass Boat Battery Setups

The most common setup for a bass boat is: The most common setup we see for bass boats with a 36 volt trolling motor recommends three 12V 50Ah batteries for the trolling motor and one 12V 125Ah battery for your engine starter and other equipment like a fish finder.

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:

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), and you’re looking for your best possible lithium set up. What do you need?
