Product Description

12 Volt 100Ah Lithium Battery

Travel trailer parked in the woods, next to a picnic table.Best Value On The Market – Ionic Lithium 12V 100Ah Deep Cycle Battery

Our 12V 100Ah battery is the perfect companion for your marine & RV adventures. Weighing 70% lighter than most lead-acid batteries, over time you’ll save loads in gas prices, not to mention wear and tear on your body. With zero-maintenance and an incredible service life of 3,000 to 5,000 cycles, this battery will go the distance.

We stand by our batteries and are happy to extend an impressive 11-year warranty with your purchase of our Ionic 12V 100Ah Battery.

Top Of The Line Safety Features

Ionic deep cycle batteries come equipped with a state-of-the-art Battery Management System (BMS). This system helps ensure that your battery is safe at all times. Controlled by a microprocessor, it monitors the main operating parameters while safely charging and discharging. This includes voltage, currents, and internal temperatures among other things. For instance, if the internal temperature of your battery is below freezing, your battery is “smart” enough to not accept a charge.

Designed To Provide Long-Lasting, Dependable Power

Not to beat a dead horse, but our 12V 100Ah battery has a cycle life between 3,000 to 5,000 cycles. On average, that’s a substantial 10 calendar years! And we can’t forget to mention capacity. With lithium, you can enjoy a capacity rating of 99%. Typical lead-acid batteries average between 50-60%. This means you’re having to charge your batteries far more often.

But what about temperature? LithiumHub deep cycle batteries handle extreme temperatures more gracefully than other battery types. In fact, our batteries can discharge between -20 degrees Celsius to 60 degrees Celsius (-4 degrees Fahrenheit to 140 degrees Fahrenheit). And they can receive a charge between 0 degrees Celsius to 45 degrees Celsius (32 degrees Fahrenheit to 113 degrees Fahrenheit).

Most Impressive Power To Weight Ratio

Need a powerful battery but working with a small space? Tired of hauling around batteries that way as much as a grade schooler? Can’t blame you. Our Ionic Lithium 12V 100Ah battery measures: 12.55″ (L) x 6.5” (W) x 9.22” (H). And it only weighs 28 lbs. The connectors are 3/8th UNC Threads. They allow the battery to be installed in any direction. Lead-acid batteries, on the other hand, must be placed in a specific direction.

With an impressive 1-3% monthly discharge rate, your cycle will outlast lead-acid by a significant amount. Lead-acid batteries usually discharge around 30% per month, after all.

Small fishing boat tied to dock.Common Uses For Your 12V 100Ah Battery

Take your adventures up a notch with our Ionic Lithium 12V 100Ah Battery. For a 24 volt trolling motor we recommend two 12V 100Ah batteries and one 12V 125Ah to take care of the engine starter and other onboard equipment. Need more power? Connect as many batteries as you need in parallel, and up to four in series. Your fishing escapades will never be the same! We know it can be difficult to figure out which size battery is best for your boat, so be sure to check out this helpful blog post.

Awesome battery

I have (6) 110ah ionics on my e-series tournament boat now to power two rear 112 Minn kota motors. We fish some good size lakes and I’m not worried about running my boat on 100% all the time. It’s has lightened my 17’ Landau tremendously. These batteries are the deal!

Ionic 100Ah Lithium

Switched over to the Ionic Lithiums this year to pair with my new Ghost trolling motor. Unbelievable batteries. I can fish several trips without even charging my batteries again, and where the batteries are Bluetooth capable you can download the app on your phone and always keep an eye on your batteries anytime you want. This is a feature I really love. No more over charging your batteries or having to guess how much battery life you have left. Ionic Batteries are a phenomenal product that I would recommend anyone to buy.

Upgraded to 125AH/Heater

I actually upgraded to the 125AH/Heater. So far it’s been an awesome experience from staff to product. 8 hrs on the water running 75-100 % on 55 lb thrust trolling motor using only 30% of capacity and no loss of power. This battery and the company is outstanding. I do plan on buying another when I up grade to a 24 volt

Awesome batteries, Great customer service and quick shipping.

Shaved a 100lbs off rear of my boat. Gets on plane quicker and by batteries @ end of day takes about 10-15 minutes to re-charge them.
