Dakota Lithium DL+ 12V 640Ah Dual Purpose LiFePO4 Battery with CAN Bus Integration

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

The DL+ 12V 640Ah is Dakota Lithium’s most powerful and compact battery to date—engineered for large-scale, off-grid energy storage and high-amp engine starting in extreme conditions. With an incredible 640 amp hours of capacity, this single unit replaces up to twelve AGM or lead-acid batteries, offering six times the usable power in a case no larger than two standard 100Ah batteries.

Delivering 1,000 cold cranking amps (CCA), this battery doesn’t just store energy—it can also jump-start trucks, boats, RVs, and off-grid systems with ease. Whether you're powering an off-grid cabin through a North Dakota winter, running air conditioning on a Skoolie, or replacing a generator on a live-aboard boat, the DL+ 640 is built for long-term, high-performance energy independence.

Designed for real-world demands, it includes internal heating for safe cold-weather charging and a CAN bus communication port to integrate with smart power systems or NMEA marine electronics. It’s perfect for building intelligent, responsive solar and mobile power setups.

Constructed with Lithium Iron Phosphate (LiFePO4) chemistry—the safest and most stable lithium platform available—the DL+ 640 is housed in a reinforced marine-grade plastic case, built to endure harsh environments. With a lifespan of 5,000+ charge cycles, it lasts up to six times longer than traditional AGM batteries, offering significantly better lifetime value.

A single DL+ 640 unit can replace a full marine or solar battery bank, run off-grid HVAC, or serve as the core power source for RVs, food trucks, workshops, barns, or cabins. Link two in parallel for full home power needs, or scale to four units for 26 kWh of storage—enough to support a four-bedroom home with solar or a working off-grid farm.

Optimized for marine, RV, solar, off-grid, and commercial applications. Includes LiFePO4-compatible charger. Backed by Dakota Lithium’s 11-year warranty.
