Product Description

Ionic 12V 4 Bank 10A Battery Charger

Charge Four Marine Batteries At Once

Keep Your Boat Batteries Charged Conveniently

When you’re hours from shore and the boat battery dies, a perfect weekend turns into an absolute nightmare. That’s why prepping for the trip with a reliable battery charger is so important.

LithiumHub’s 4-Bank Marine Charger gives you the power you need to enjoy your time on the water; conveniently and reliably.

So, what type of boat charger do you need? And aren’t they expensive? Well… Most of them are, but a rare few happen to be both affordable and high-quality. Enter the 4-Bank Marine Charger.

The 4-Bank Marine Charger can charge four lithium, AGM, or lead-acid batteries simultaneously.

It’s extra lightweight, affordable, and capable. With this charger, you’ll save loads of time and enjoy the simplicity of charging your batteries with a strong and reliable multi-bank marine battery charger. Let’s explore the benefits.

Benefits Of Owning The 4-Bank Marine Battery Charger

  • Charges your batteries faster and more conveniently
  • Charges up to four 12V lithium batteries at once
  • Can charge lead-acid and AGM batteries
  • Five-foot cable length
  • Colored lights indicate the charging status
  • Ionic Lithium app shows charge level when using Ionic Lithium Batteries
  • Lightweight
  • Affordable

The 4-Bank Marine Charger Advantage

The 4-Bank Marine Charger charges up to four 12V lithium batteries at a time. No electrical problems, no design flaws — nothing but easy, battery charging power. It’s designed for success and we’re sure you’ll get nothing less from it. (And even if you did, your purchase includes a one-year warranty for the product.)

The 4-Bank Marine Charger is one of the first on-board boat chargers with the ability to charge lithium batteries, which is great, but what if you have lead-acid or AGM batteries? No problem at all — the versatile 4-Bank Marine Charger works for them too. Also, you don’t have to place the batteries right next to the charger, because the 4-bank lithium battery charger has five-foot cables on each bank, giving you some reach to work with.

Our boat charger has lights that indicate the charge level. A red light means the battery is still charging, while a green light means it’s complete, plus, with Ionic Lithium Batteries, the Ionic Lithium app will tell you its charge in real time.

Some battery chargers are bulky, heavy, and awkward, but the 4-Bank Marine Charger only weighs eleven pounds; the lightest of its kind. On top of that, it’s small: the battery charger measures 12in x 9.5in x 2in.

Lastly, the 4-Bank Marine Charger is affordable. More affordable, in fact, than just about any 4 bank marine battery charger on the market. Besides the excellent warranty, the battery charger comes with the LithiumHub 30-Day Return Policy and free shipping. So is it worth it? We think so, but we’ll let you do the math.

Is The 4-Bank Marine Battery Charger A Good Investment?

Boats can be quite an investment, so it’s good to weigh each cost and choose wisely.

It really boils down to a couple things. Can you get away with having a low-quality battery charger you don’t trust? And do you need a multi-bank marine charger to begin with?

This is how we see it. First, if you like saving a lot of time and enjoy the overall convenience of being able to charge up to 4 batteries at a time, a multi-bank boat charger is definitely in your wheelhouse.

Second, if you don’t want to miss out on a great boating weekend because of a dead on-board marine charger (not to mention the joys of searching for another not-so-cheap charger), you’ll want a good, reliable charger that stands the test of time.

So quality is also a must. But you don’t want to spend more than you have to either, and most multi-bank battery chargers are the polar opposite of affordable.

It’s the combination of all these things that makes this charger, in our humble opinion, the best option on the market.

The quality and features of our 4-Bank Marine Charger match some of the most expensive models available. It’s a well-designed, reliable marine charger that can charge four batteries at once and is able to survive and thrive under hostile marine and other outdoor environments.

Ultimately, we know you value convenience and quality, and your satisfaction is our top priority. That’s why we’re proud to make products like the 4-Bank Marine Charger, which has lived up to customer expectations every step of the way.

The Ionic 4-bank lithium charger charges 12V (LiFePo4) batteries individually at 10A on each channel. The charger can be used for 48V, 36V, 24V, or 12V systems (12V in series).  This charger can also be used to charge lead acid or AGM batteries. It can be used for 2 or 3 bank charging systems too by doubling up on different banks.  The 4 bank charges to 14.6V by constant current at 10A then floats to 13.8V.  Weighing only 11 lbs with a size of 12in x 9.5in x 2in gives this charger a low profile and is one of the lightest chargers on the market.

Makes a great charger for Ionic Lithium Batteries and lead acid batteries.

Frequently Asked Questions

What's this charger for?

It’s a 4-bank 12V marine charger that charges up to four 12V batteries at once at 10A per bank — ideal for a bigger boat running a multi-battery trolling-motor bank plus cranking and electronics batteries. It can also be used as a 2- or 3-bank charger by using fewer banks.

Can it charge 24V, 36V, or 48V systems?

Yes — it can charge 12V, 24V, 36V, or 48V systems made up of 12V batteries in series, and it works with LiFePO4 lithium, AGM, and lead-acid batteries. Each bank charges at 10A to 14.6V, then floats to 13.8V.

Can I mount it on my boat?

Yes — it’s compact (12 × 9.5 × 2 in) and one of the lightest 4-bank chargers available, designed to mount onboard in tight spaces. Each bank has a 60-inch (5-foot) cable so you can position batteries away from the charger. Ionic also offers an optional Charger Mount (fits the 2-, 3-, and 4-bank chargers) for better airflow and mounting flexibility.

Can I monitor charging from my phone?

Yes — when charging Ionic lithium batteries, the Bluetooth-connected Ionic app shows each battery’s charge level and estimated time to charge. (Bluetooth monitoring works only with lithium batteries; lead-acid/AGM charge normally without app data.)

Is it safe to leave connected?

Yes — it uses a constant-current/constant-voltage (CCCV) profile and stops at 14.6V when full, then floats at 13.8V to maintain the charge. As a safety measure it also times out after 72 hours of continuous charging (shown by blinking red LEDs); to restart, disconnect and reconnect the power cable.
