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
Weight: 65 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. Do not charge below 32°F.
Operating temperature: Ideal for rugged & harsh environments. Much better than SLA or other lithium’s.-4°F to 158°F (-20°C to 70°C). BMS cutoff at 167°F (75°C).
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 & Water resistant: 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.

Recommended Charger: 12V 50A (sold separately)
