Dakota Lithium Batteries & Chargers

Why Choose Dakota Lithium for Your Next Power Upgrade?

For decades, lead-acid and AGM batteries were the only choice, but they came with heavy compromises: back-breaking weight, short lifespans, and a "50% rule" that meant you could only use half the energy you paid for. Dakota Lithium changes the game. By using premium Lithium Iron Phosphate (LiFePO4) chemistry, these batteries provide a steady, flat voltage curve. This means your electronics and motors run at full strength until the battery is nearly empty—no more dimming lights or weakening motors as the day goes on.

Reliability Backed by an 11-Year Warranty

We know that reliability is your top priority. Every core Dakota Lithium battery comes with an 11-year manufacturer defect warranty. This isn't just a number; it’s a promise that your investment is protected for over a decade of use. If you ever have a question about setup or performance, Battery Mart’s technical team and Dakota’s lifetime support are here to help you get the most out of your system.

Choosing Your Capacity: From 10Ah to 100Ah+

Our catalog covers the full breadth of power needs, ensuring you don't carry more weight than necessary. Here is how our most popular sizes are typically used:

• 10Ah to 25Ah: Small but mighty. Perfect for fish finders, ice fishing flashers, and small portable electronics.
• 54Ah to 60Ah: The "sweet spot" for many users. Ideal for smaller trolling motors, kayaks, and portable solar generators.
• 100Ah and Up: The workhorses. These are the standard for RV house batteries, off-grid power systems, and multi-day fishing trips.
• 24V & 36V Systems: We offer dedicated high-voltage units to simplify your wiring for modern, high-thrust trolling motors.

The Advantage of Lithium Cranking Power

While lithium is famous for deep-cycle use, Dakota Lithium has engineered select models to provide incredible cranking amps. This allows boaters to use a single battery for both starting their outboard motor and running their electronics, further reducing weight and clutter on the water.

Built for the Toughest Conditions

Dakota Lithium batteries are engineered for folks who don't let the weather dictate their plans. While standard lithium batteries can struggle in the cold, many Dakota models feature internal "Even-Heat" technology, allowing them to charge and perform in extreme northern winters down to -20°F. They are also vibration-resistant and IP65-rated for water resistance, making them the perfect companion for rugged marine and off-road environments.

Frequently Asked Questions

Can I use my existing lead-acid charger?

While a standard lead-acid charger may provide a partial charge, we highly recommend using a LiFePO4-compatible charger. Lithium batteries require a higher voltage (typically 14.4V) to reach 100% capacity. Using the correct charger ensures your battery stays healthy and reaches its maximum lifespan.

Is it really a "drop-in" replacement?

Yes. Dakota Lithium batteries are designed in standard BCI group sizes. This means they will fit into the same battery trays and boxes used by your old lead-acid batteries, though you’ll immediately notice how much easier they are to lift and install.
