Perfect for RVs, Boats, Home Solar & More
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 power an off grid farm or home during a cold North Dakota winter, the DL+ 12V 640 Ah battery is our most compact and powerful battery yet -- ready for long expeditions in your RV, extended ocean voyages in your boat, or plenty of power for your air conditioner or off grid system. Engineered for maximum energy density, this battery has 640 Amp Hours of capacity in a waterproof battery case the size of a two 100 Amp Hour batteries. That's 6X the amount of usable power, allowing you to replace a marine or solar battery bank of 12 AGM or lead acid batteries with a single DL+ 640Ah. Plus 1,000 cold cranking amps of engine starting power, making this battery the ultimate single battery solution for boats, RVs, food trucks, barns, garages, workshops, or any vehicle or space where you need a house battery that can jump start your engine. Also includes internal heating for charging in extreme cold. CAN bus communication port allows the battery to talk CAN bus electronics, allowing you to build smart power systems. Built out of Lithium Iron Phosphate (LiFePO4) technology and reinforced with a ruggedized marine spec plastic case, this is a battery built to last. With a lifespan of 5,000 charge cycles this battery will last up to 6 times longer than your typical AGM battery - providing exceptional value over time. Optimized for marine/boating, solar energy, RVs & electric vehicles. LiFePO4 optimized charger included. 11 year warranty. Link in parallel for added capacity. 1 unit is perfect for replacing the need for a generator on a large boat, very large RV, Skoolie, or off grid cabin or installing an off-grid air conditioning system. 2 units is ideal for most off grid homes. 4 units is 30 kwh of energy storage and is enough for a large 4 bedroom home with a solar array, a working farm, or business.
Warranty
Best in Class 11 Year Warranty. That is 10 years more warranty then most lead acid batteries.
Storage Capacity
640Ampere 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 Amps
1,000 CCA is adequate to start most boat and large vehicle engines
Energy
7680Wh
Voltage
12.8 Volts (Dakota Lithium 12V batteries can be used in series for up to 48V systems)
Size
27"L x 8.07"W x 10.43"H (686mm ×205mm × 265mm). Height is to the top of the terminals.
Weight
121 lbs (55Kg)
Lifespan/Lifecycles
Up 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.
Discharge
300A 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.
Charge
100 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 temperature
Ideal 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 TECHNOLOGY
Increases 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 & Reliable
Includes 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 Posts
M10 Terminals with marine & automotive grade terminal covers.
Marine Grade & Waterproof
Max IP65 water resistance rating. Appropriate for marine environments, not submersible.
Certifications
Dakota 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 9001:2015
Dakota 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 Included
12V 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 bus
CAN 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 port
Control 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.
