Product Description

12 Volt 100Ah Lithium Battery

Best Value On The Market – Ionic Lithium 12V 100Ah Deep Cycle Battery

Our 12V 100Ah lithium battery, with its 100 amp hours capacity, is the perfect companion for your marine & road adventures and beyond, whether you’re using it for your bass boat, trolling motor, RV, solar panels and solar energy storage, or emergency backup power.

These days, it’s crucial to consider Lithium Iron Phosphate (LiFePO4) batteries. Because they bring unprecedented features and benefits to the table beyond optimal charging parameters, higher depth of discharge, compatibility with various systems, and optimal performance.

Here’s a Brief Snapshot of How Lithium Batteries Outperform Lead Acid:

  • 70% Lighter
  • Lasts 2-4x longer (generally 10 years and up)
  • Backed by 11-Year Warranty
  • Zero Maintenance
  • Consistent Voltage (Which makes them ideal for RVs and solar power systems)
  • 200% Power
  • 500% Faster Charging
  • Built-in Overcharge & Over-discharge Protection
  • Cold Weather Protection
  • Safer Chemistry & No Sulfation Issues
  • Handles VERY High Discharge (99% Depth of Discharge)
  • Fast and Free Shipping in the U.S.
  • More Usable Capacity

With less than half the weight (70% lighter than traditional batteries like lead-acid batteries), you’ll save loads in gas prices over its long-lasting life and superior battery life performance (not to mention wear and tear on your body). With zero maintenance and an incredible service life of 3,000 to 5,000 cycles, your LiFePO4 (lithium iron phosphate) battery will go the distance. We stand by our lithium batteries and are happy to extend an impressive 11-year warranty with your purchase of our Ionic 12V 100Ah Battery. Sidenote: These are not lithium-ion batteries – they’re Lifepo4 batteries.

Top Of The Line Safety Features

Ionic 12v 100ah lithium batteries come equipped with a state-of-the-art Battery Management System (BMS) for safety reasons. This system helps ensure that your battery stays safe at all times. Controlled by a microprocessor, it monitors the main operating parameters while safely charging and discharging. That includes voltage, currents, and internal temperatures (and other things). For instance, if the internal temperature of your battery is below freezing, your LiFePO4 battery is “smart” enough to not accept a charge.

Designed To Provide Long-Lasting, Reliable Power

Not to beat a dead horse, but our 12V 100Ah lithium 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%. A lead acid battery averages between 50-60%. That 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. Our 12V 100Ah LiFePO4 batteries can discharge between -20 degrees Celsius to 60 degrees Celsius (-4 degrees Fahrenheit to 140 degrees Fahrenheit). They can receive a charge between 0 degrees Celsius and 45 degrees Celsius (32 degrees Fahrenheit and 113 degrees Fahrenheit).

 

12V 100Ah Lithium: Most Impressive Power To Weight Ratio vs Lead Acid Batteries

Need a powerful battery for a small space? Tired of hauling around super-heavy batteries? Can’t blame you. Our Ionic 12V 100Ah lithium battery is 12.55″ (L) x 6.5” (W) x 9.22” (H). And it only weighs 28 lbs. The connectors are 3/8th UNC Threads. With a single battery, you can power multiple devices, making it an efficient choice for various applications. You can install the battery 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 significantly outlast lead-acid and AGM batteries. Lead-acid batteries usually discharge around 30% per month, after all.

Real-Time Monitor For Your Lithium Batteries

With the Ionic Blue Batteries app, you can monitor the real-time status of your battery on your phone. This is smart energy monitoring at its best. You have all the real-time information you need about your battery, right in your pocket.

Common Uses For Your 12V 100Ah Battery

Small fishing boat tied to dock. Take your adventures up a notch with our Ionic Lithium 12V 100Ah Battery. For 24-volt trolling motors, we recommend two 12V 100Ah batteries and one 12V 125Ah to take care of the engine starter and other onboard equipment.

Need more power, consistent 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’s hard to decide which size battery is best for your boat, so check out this helpful blog post.

Beyond its many uses as a marine battery, our 12V 100Ah lithium battery is also a strong option for RVs, solar storage, off-grid systems, and more thanks to its many benefits including faster charging and longer-lasting performance.

Other important things to note: 

  • Max charge current for our 12 volt lithium battery 100ah is 14.6V, with the maximum discharge voltage being 10.5V.
  • The max charge current is 100A and the max discharge is 100A/350A(3s).
  • Our 12V 100Ah battery works with solar chargers!
  • Can be charged with most traditional lead-acid chargers. (Chargers that don’t have “Desulfate” mode. And provided the current levels do not exceed lithium battery charge specification.)
  • You can charge your 12V 100Ah lithium battery with a standard lead-acid charger that achieves 14.4-14.6 volts.
  • Chargers with a voltage of fewer than 13.6 volts will only charge at 50% capacity or less.
  • This battery is covered by our industry-leading 11-year warranty.

Frequently Asked Questions

Can this battery both start my outboard motor and run my trolling motor or electronics?

Yes — it’s a true dual-purpose battery. It delivers 900 CCA and can start outboards up to 200hp from Yamaha or Mercury, while its 100Ah capacity and 99% usable depth of discharge make it an excellent deep-cycle battery for trolling motors, electronics, and house loads. LithiumHub has had customers using it as a cranking battery since 2019 without issues.

Can I use these for a 24V or 36V trolling motor?

Yes. For a 24V trolling motor, run two 12V 100Ah batteries in series; for 36V, run three in series (up to 4 in series total). Many anglers add a separate battery for the engine starter and onboard electronics. You can also connect as many as needed in parallel to extend run time.

Will this battery fit my Group 31 battery tray?

Yes. As of 11/25/25 all 12V 100Ah batteries ship in the new BCI Group 31 case at 13″ × 6.75″ × 9″ (330 × 171 × 229 mm), weighing just 24 lbs. The new case also adds a carrying strap/handle, which customers note makes it much easier to install in tight rod-locker compartments. The 3/8″ terminals let you mount it in any orientation.

What chargers are compatible with this battery?

Compatible chargers include Ionic, NOCO Gen Pro, Dual Pro PS/Auto, Minn Kota Precision, Pro Mariner / Pro Tournament Elite, Stealth, Troll Bridge DC, and Power Pole. Any LiFePO4-compatible charger that reaches 14.4 – 14.6V (within the 100A max charge current) works. You can use solar chargers and most lead-acid chargers that reach 14.4 – 14.6V — just avoid any with a “Desulfate” mode. Chargers below 13.6V will only charge to 50% or less.

How long will this battery last?

The 12V 100Ah is rated for 3,000–5,000 cycles — roughly 8-10 years of real-world use and 2-4x the service life of a comparable lead-acid battery. It runs at 99% usable capacity, self-discharges only 1-3% per month (vs. ~30%/month for lead-acid), and is backed by LithiumHub’s 11-year warranty.
