PERFECT FOR RVS, BOATS, HOME SOLAR AND MORE

Experience the ultimate off-grid power with Dakota Lithium's newest addition to their high-performance battery line - the DL+ 12V 320Ah dual purpose battery. Boasting a waterproof Group-31 size case, this compact battery packs an impressive 320 Amp Hours of capacity and up to 1,000 cold-cranking amps (CCA) for engine-starting power. Perfect for RVs, boats, and vehicles needing both house and starting power, this battery is 6X more powerful than a single Group-31 AGM battery.

Technical Specifications : 

• Warranty: Best-in-class 11-year warranty, offering 10 years more than typical lead-acid batteries for unparalleled peace of mind.
• Storage Capacity: 320Ah, providing steady power throughout the full discharge cycle. The flat voltage curve of LiFePO4 chemistry ensures consistent output until fully discharged, unlike SLA batteries that experience a rapid drop in voltage.
• Cold Cranking Amps (CCA): 1,000 CCA, which is adequate for starting most boat and large vehicle engines.
• Energy Output: 3840Wh, significantly higher than equivalent lead-acid options.
• Voltage: 12.8V (can be used in series for systems up to 48V).
• Size: 15.06”L x 7.24”W x 10”H (385mm x 202mm x 252mm), including side handles. Check product description for compatibility with battery tray and box sizes.
• Group Size: Compatible with Group 31 and Marine 8D battery sizes.
• Weight: 65 lbs (29.5 kg), offering a substantial reduction in weight compared to traditional lead-acid batteries.
• Lifespan: Up to 80% capacity for 5,000 cycles in optimal conditions. Expect 70% capacity at 5,000 cycles, with half-life around 6,000-7,000 cycles. Traditional SLA batteries typically last only 500 cycles.
• Discharge: 200A max continuous, 300A max 10-second pulse, 1,000A max 2-second CCA pulse. The flat discharge voltage curve ensures stable power for most applications.
• Charging: Standard charge rate of <200A, with a maximum charge current of 300A for under 60 seconds. Recommended charge voltage: 14.4V, with a maximum of 14.6V. Internal heating technology allows for charging even in cold temperatures down to 0°C/32°F.
• Operating Temperature: Designed for rugged environments, the battery operates between -20°F and +150°F. It also includes internal heating to ensure safe charging in cold temperatures. The BMS has a high-temperature cutoff at 167°F / 75°C.
• Internal Even-Heat Technology: This feature improves performance in extreme cold by warming the cells to 32°F when charging in sub-zero temperatures, enhancing both efficiency and lifespan.
• Safety & Reliability: The built-in Battery Management System (BMS) ensures safe operation with features like cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection, and high-temperature protection.
• Terminals & Posts: M8 bolt size (max torque: 15 ft-lbs, max 5 ft-lbs on terminal post adapters).
• Waterproof Rating: IP65 water resistance rating, suitable for marine environments but not submersible.
• Certifications: UN38 certified, UL1642 certified, and tested per IEC62133 standards. Complies with all US and international regulations for transport via air, ground, train, and marine.
• ISO Certification: Manufactured in ISO 9001:2015 certified facilities, with select models produced in ISO 14001 certified plants.
• Recommended Charger: 12V 20A charger (sold separately). Charge at 14.4V for optimal performance; using lead-acid chargers will only charge the battery to 80% capacity.
