Overview
Dakota Lithium DL+ 12V 320Ah Battery – Ultimate Power for Off-Grid, Marine & RV Applications
Designed for off-grid adventures, marine use, RVs, and high-power applications, the Dakota Lithium DL+ 12V 320Ah Battery delivers unmatched performance, longevity, and reliability. Packed into a rugged, waterproof Group-31 case, this battery provides 320 Amp Hours of deep-cycle power alongside 1,000 Cold Cranking Amps (CCA) for engine starting—making it the perfect all-in-one solution for boats, RVs, and off-grid power systems. With 6X the usable power of a standard AGM battery and a lifespan of 5,000+ charge cycles, this battery ensures long-term efficiency, durability, and energy independence.
KEY FEATURES
- High-Capacity Power – 320Ah of deep-cycle energy for extended off-grid performance.
- Dual-Purpose Design – 1,000 CCA for reliable engine starting, making it ideal for marine, RV, and vehicle applications.
- Compact & Efficient – Fits a Group-31 battery footprint (13.31"L x 7.24"W x 10"H), with a slightly wider top (15.04" x 7.60" x 9.96")—ensuring a powerful yet space-saving design.
- Lithium Iron Phosphate (LiFePO4) Technology – 6X the power and 8X longer lifespan than AGM batteries, lasting up to 5,000 cycles for long-term value.
- Rugged & Durable – Reinforced marine-spec plastic case ensures durability in harsh environments.
- Waterproof & Weather-Resistant – Engineered to withstand extreme conditions, perfect for marine and off-grid solar applications.
- Faster Charging & Efficiency – Charges 5X faster than lead-acid batteries, with minimal self-discharge for reliable long-term storage.
- Optimized for: Marine applications, RVs, solar energy storage, off-grid power systems, and electric vehicles.
- Industry-Leading Warranty – Backed by an 11-year warranty, providing confidence in durability and performance.
Specifications
Warranty
Best in Class 11 Year Warranty. That is 10 years more warranty then most lead acid batteries.
Storage Capacity
320 Ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 320 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
3840Wh
Voltage
12.8 Volts (Dakota Lithium 12V batteries can be used in series for up to 48V systems)
Size
L: 15.04" x W: 7.60" x H: 9.96" (382mm x 193mm x 253mm) Measurements are to the top of the terminals and includes side handles. See notes in the product description for battery tray and battery box sizing
Group Size 31 & 8D
Group Size 31 and Marine 8D size compatible
Weight65 lbs (29.5Kg)
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
Max continuous 200A, 300A for 60 seconds, 1000A for 1 second.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
<200 A standard charge, 300A max charge current for <60 sec. 14.4V Recommended, 14.6V Max. 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. -4°F to 176°F (-20°C to 80°C) 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
M8 bolt size included. (Max torque 15 ft. lbs.) (Max 5 ft. lbs. on terminal post adapters)
Marine Grade & Waterproof
Max IP65 water resistance rating. Appropriate for marine environments, not submersible.
Certifications
All batteries are UN38 certified. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. Meets all US & International regulations for air, ground, train, & marine transport.
ISO 9001:2015
Dakota Lithium is ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.
Recommended Charger
12V 50A charger. (Sold Separate) 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.
