Introducing the All-New DL+ 12V 320Ah Battery: Bigger, Stronger, More Powerful Prepare for the toughest conditions with the new DL+ 12V 320Ah battery, the latest in Dakota Lithium's line of high-performance batteries. Built for off-grid adventures in your RV, extended ocean voyages, and powerful off-grid systems, this battery is compact, yet packed with 320 Amp Hours of capacity in a waterproof Group-31 size case. That’s 6X the usable power of a single Group-31 AGM battery, plus up to 1,000 cold-cranking amps (CCA) for engine-starting power, making it the ultimate single-battery solution for boats, RVs, and vehicles requiring both house and starting power. Key Features:
-Superior Power:320 Amp Hours of capacity and 1,000 CCA for reliable power, whether off-grid or starting engines.
-Compact Design:Fits in a Group-31 size footprint with dimensions of 13.31"L x 7.24"W x 10"H, though the wider top (15.06"L x 7.24"W x 10"H) may require checking battery box compatibility.
-Lithium Iron Phosphate (LiFePO4) Technology:Delivers 6X the power and lasts up to 8 times longer than typical AGM batteries, with a lifespan of 5,000 charge cycles.
-Durable Construction:Reinforced with a rugged, marine-spec plastic case for enhanced durability, making it ideal for marine, solar, RV, and electric vehicle applications.
-Waterproof and Built to Last:Designed for extreme environments, offering unmatched performance and an 11-year warranty for long-term value.
-Optimized for: Marine/boating, solar energy, RVs, and electric vehicles. For those seeking maximum energy density in a compact, durable design, the DL+ 12V 320Ah is the ultimate power solution. Whether you're exploring off-grid or sailing the open seas, this battery provides the performance and reliability you need. Recommended Charger: 12V 20A or 12V 50A (sold separately)
Tech Specs:
WarrantyBest in Class 11 Year Warranty. That is 10 years more warranty then most lead acid batteries.
Storage Capacity320 Ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 315 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
Energy3840Wh
Voltage12.8 Volts (Dakota Lithium 12V batteries can be used in series for up to 48V systems)
Size15.06"L x 7.24"W x 10"H (385mm x 202mm x 252mm) 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 & 8DGroup Size 31 and Marine 8D size compatible
Weight65 lbs (29.5Kg)
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.
Discharge200A max continuous, 300A max 10-second pulse, 1,000A max 2-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<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 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 PostsM8 bolt size included. (Max torque 15 ft. lbs.) (Max 5 ft. lbs. on terminal post adapters)
Marine Grade & WaterproofMax IP65 water resistance rating. Appropriate for marine environments, not submersible.
CertificationsAll 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 9001:2015Dakota Lithium is ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.
Recommended Charger12V 20A 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.
