Dakota Lithium DL+ 12V 640Ah Dual Purpose LiFePO4 Battery

Dakota Lithium DL+ 12V 640Ah Dual Purpose LiFePO4 Battery

A 121-lb high-capacity lithium battery designed for RVs, large boats, solar banks, and off-grid power systems.

An incredible 640 Amp Hours of capacity allows you to replace 12 AGM or lead acid batteries with a single DL+ battery. Plus 1,000 CCA of engine starting power, internal heating while charging for use in extreme cold, and CAN bus and NMEA communication.

Built to endure the harshest conditions—like a frigid North Dakota winter—the DL+ 12V 640Ah is Dakota Lithium’s most compact and powerful battery yet. Whether you’re embarking on long expeditions in your RV, extended ocean voyages, or powering essential systems like air conditioners and off-grid setups, this battery delivers unmatched performance. Engineered for maximum energy density, it packs 640 amp hours of power into a waterproof case the size of two 100Ah batteries. That’s 6x the usable power, making it a game-changer for replacing large marine or solar battery banks of up to 12 AGM or lead-acid batteries with just one DL+ 640Ah.

With 1,000 cold-cranking amps of engine-starting power, this battery is the ultimate all-in-one solution for boats, RVs, food trucks, barns, garages, and workshops—capable of jump-starting engines while acting as a powerful house battery. It’s also equipped with internal heating, ensuring reliable charging even in extreme cold. The CAN bus communication port allows seamless integration with CAN bus electronics, making it ideal for building smart power systems.

Constructed with advanced Lithium Iron Phosphate (LiFePO4) technology and encased in rugged, marine-grade plastic, this battery is built for durability and longevity. With a 5,000-cycle lifespan, it lasts up to 6 times longer than typical AGM batteries, delivering exceptional value over time. Perfect for applications in marine, solar energy, RVs, and electric vehicles, all backed by an 11-year warranty.

For larger power needs, the DL+ 640Ah can be linked in parallel for added capacity. One unit can replace a generator on a large boat, oversized RV, Skoolie, or off-grid cabin, while two units are ideal for most off-grid homes. For even more energy storage, four units provide 30kWh, enough to power a large 4-bedroom home with a solar array, working farm, or business.
