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

Step into a new era of energy independence with the Dakota Lithium DL+ 12V 640Ah Dual Purpose Heated LiFePO4 Battery. This is more than just a battery; it's a revolutionary all-in-one power system engineered to deliver unparalleled deep-cycle capacity and robust engine-starting power, even in the most extreme conditions. With massive energy reserves, intelligent features, and an industry-leading lifespan, the DL+ 640Ah is the definitive choice for large RVs, marine vessels, off-grid homes, and heavy-duty industrial applications.

Key Features:

• Massive 640 Ampere-Hour (Ah) Capacity: Replace up to 12 traditional lead-acid or AGM batteries with a single DL+ 640Ah unit. With an incredible 7680 Watt-hours (Wh) of energy, it provides extended runtimes for all your high-demand appliances, electronics, and systems. Power air conditioners, large inverters, and entire off-grid setups with confidence.

• 1,000 Cold Cranking Amps (CCA): Don't compromise on starting power. The DL+ 640Ah delivers a formidable 1,000 CCA, ensuring reliable and instantaneous engine starts for the largest boats, RVs, and vehicles, making it a true dual-purpose workhorse.

• Integrated Even-Heat Technology: Conquer the coldest climates. Our intelligent internal heating system automatically activates below 0∘C(32∘F) when charging. It precisely warms the cells to optimal temperatures before allowing current, ensuring safe and efficient charging in environments down to −20∘C(−4∘F), and extending the battery's overall lifespan.

• Astonishing Lifespan: 5,000+ Deep Cycles! Experience unprecedented longevity. Built with advanced Lithium Iron Phosphate (LiFePO4) chemistry, this battery offers an incredible 5,000 cycles to 80% capacity (and up to 7,000 cycles to 50% capacity). This means years, even decades, of reliable power, dramatically reducing replacement costs and maintenance.

• Consistent, Flat Voltage Curve: Unlike lead-acid batteries that sag under load, the DL+ 640Ah maintains a stable, consistent voltage throughout its discharge cycle. This ensures peak performance for all your sensitive electronics, lights, and appliances, delivering full power right down to the last drop.

• Advanced Battery Management System (BMS) with CAN Bus: The integrated BMS offers comprehensive protection against overcharge, over-discharge, short circuits, over-current, and extreme temperatures. Plus, with a built-in CAN bus communication port, you can seamlessly integrate the battery with smart power systems, marine electronics (NMEA 2000 compatible), and industrial dashboards for real-time monitoring and control.

• Lightweight and Space-Saving Design: Weighing in at just 121 lbs (55 kg), the DL+ 640Ah is significantly lighter than comparable lead-acid banks, improving fuel efficiency and handling in mobile applications. Its compact size replaces multiple traditional batteries, freeing up valuable space.

• Rugged, Marine-Grade Construction: Engineered for the harshest environments. Housed in a reinforced, marine-spec plastic case with an IP65 water resistance rating, this battery is highly resistant to vibrations, splashes, dust, and corrosive elements, making it ideal for marine and off-road use (not submersible).

• Remote Terminal Control Capability: For advanced system builders, two analog control pins allow external or remote disabling of charging or discharging functions, providing unparalleled control for automated or smart-grid projects.

• Best-in-Class 11-Year Warranty: Dakota Lithium stands behind the DL+ 640Ah with an industry-leading, non-transferable 11-year manufacturer defect warranty, plus free lifetime technical support. This commitment ensures peace of mind and long-term value.

• Eco-Friendly & Safe: Utilizing stable LiFePO4 chemistry, this battery is non-toxic, emits no gases, and is inherently safer than other lithium chemistries, making it an environmentally responsible power choice.
