DL+ 12V 640Ah LiFePO4 Dual Purpose Battery With Can Bus

Perfect for RVs, Boats, Home Solar & More

Product Description

The DL+ 12V 640Ah Dakota Lithium battery is designed for off-grid farms, homes, RVs, and boats, providing 6X the usable power of standard batteries. With 640 Amp Hours and 1,000 CCA, it replaces up to 12 AGM or lead acid batteries, making it perfect for high-demand systems like air conditioning or off-grid setups. Built with Lithium Iron Phosphate (LiFePO4) technology, it lasts 6X longer with 5,000 charge cycles. It includes internal heating for cold climates, a CAN bus port for smart power systems, and a waterproof case. The battery comes with a LiFePO4 charger, an 11-year warranty, and can be linked in parallel for larger systems.

Technical Specifications

WarrantyBest in Class 11 Year Warranty. That is 10 years more warranty then most lead acid batteries.

Storage Capacity640Ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 640 Amp hours. DL LiFePO4 batteries have a flat voltage curve, which means they have a steady power output as the battery discharges. The power output will not dramatically drop like similar sized SLA batteries. You get all the juice down to the last drop.

Cold Cranking Amps1,000 CCA is adequate to start most boat and large vehicle engines

Energy7680Wh

Voltage12.8 Volts (Dakota Lithium 12V batteries can be used in series for up to 48V systems)

Size27"L x 8.07"W x 10.43"H (686mm ×205mm × 265mm). Height is to the top of the terminals.

Weight121 lbs (55Kg)

Lifespan/LifecyclesUp to 80% capacity for 5,000 cycles in recommended conditions, 70% capacity at 5,000 recharge cycles. Half-life (50% capacity) of 6,000 - 7,000 re-charge cycles (Typical SLA has 500 cycles). Backed up by an 11 year warranty.

Discharge300A max continuous, 600A max 20-second pulse, 900A max 5-sec CCA pulse. LiFePO4 chemistry has a flat voltage curve, meaning this battery will maintain a voltage of >12V for the full discharge cycle in most applications.

Charge100 A standard charge, 300A max charge current for 60 sec. Included is a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery. Even heat technology allows for charging below 32'F. Internal even-heat technology allows for charging below 0°C/32°F

Operating temperatureIdeal for rugged & harsh environments. Much better than SLA or other lithium batteries. -20°F min, +150°F max optimal operating temps (battery performs well down to -20°F). Internal even-heat technology allows for charging below 32°F. BMS high temp cut off at 167°F / 75°C..

INTERNAL EVEN-HEAT TECHNOLOGYIncreases performance in extreme cold. When charging the battery in temperatures below 0°C/32°F DL's internal heating element will warm the cells to 0°C/32°F. This increases the lifespan, performance, and efficiency of the battery.

Safe & ReliableIncludes active BMS protection circuit that handles cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and high temperature protection for increased performance and longer life

Terminals and PostsM10 Terminals with marine & automotive grade terminal covers.

Marine Grade & WaterproofMax IP65 water resistance rating. Appropriate for marine environments, not submersible.

CertificationsDakota Lithium's cells are UL1642 certified and have been tested per IEC62133 and UN 38.3 standards. They meet all US and international regulations for air, ground, and train transport.

ISO 9001:2015Dakota Lithium is certified by ISO 9001:2015 for lithium battery engineering, manufacturing, and quality control. This means that the battery systems available at Dakota Lithium are designed and manufactured to the highest ISO 9001:2015 engineering standards. In addition, quality control is completed by our US based engineering team and follows ISO 9001 standards. This added layer of safety, quality, and reliability ensures that your battery will last a long, long time.

Free LiFePO4 Charger Included12V 50A charger included ($299 value). Dakota Lithium 12V batteries should be charged at 14.4 volts. Lead acid chargers will work, but will only charge the battery to 80% of capacity.

CAN busCAN bus communication port for connecting to marine, off grid, and automotive electronics. 9 pin CAN plug with hardware included.

On/Off control of battery terminals via external data portControl the terminals of your pack externally, or remotely. Two analog control pins allow you to connect either or both to a (third) power pin to disable charging or discharging. Independent Charge/Discharge shut offs can be triggered by an external switch or logic controller. Shut off only the charging function, or only the discharging function, or both, and re-activate them at will. Useful in larger automated systems or local smart-grid projects.
