Product Description
With the new DL+ 12V 320Ah battery, we built 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 off grid system. Engineered for maximum energy density, Dakota Lithium has packed 320 amp hours (Ah) of capacity in a waterproof battery case the size of a single Group 31 battery. That’s 6X the amount of usable power of a single Group 31 AGM battery. Plus, up to 1,000 cold cranking amps of engine starting power, making this battery the ultimate single battery solution for boats, RVs, or any vehicle where you need a house battery that can jump start your engine. 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. Lithium deep cycle battery durability, backed by an 11 Year Warranty. A Dakota Lithium 20A charger is included.
Common Applications
- Boating & Sailboat Batteries
- RV’s
- Off Grid Energy Storage
- Vans & Campers
- Home Energy Storage
- Solar Storage
- DIY Powerwalls
- Emergency Power
- Golf Carts
- Neighborhood Electric Vehicles (NEV)
Warranty
Best in Class 11 Year Warranty. That is 10 years more warranty then most lead acid batteries.
Storage Capacity
320 amp hours. Dakota Lithium batteries provide consistent power for all 320Ah's. 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.
Energy
3840 watt hours (Wh).
Voltage
12.8 Volts (Dakota Lithium 12V batteries can be used in series for up to 48V systems).
Size
15.06"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. Base of battery measures 13.31" x 7.24" (338mm × 184mm) to fit in a standard Group 31 battery tray. Because of the larger top dimensions with handles, this battery may not fit in standard Group 31 battery boxes.
Group Size 31 & 8D
Group Size 31 and Marine 8D size compatible. See top/bottom dimensions in Size section above for details.
Weight
61 lbs (27.7Kg).
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
200A max continuous, 300A max 10-second pulse, 1,000A max 2-sec CCA pulse. Lithium batteries have a flat voltage curve, meaning this battery will maintain a voltage of >12V for the full discharge cycle in most applications.
Charge
<200A standard charge, 300A max charge current for <60 sec. 14.4V Recommended, 14.6V Max. A Dakota Lithium 20A charger is included.
Alternator Charging
We do not recommend this battery for automotive or other applications where it would be directly charged off an alternator. To be charged off an alternator, this should be an auxiliary battery and a DC-DC charger like the Orion-Tr Smart Charger installed in order to charge the battery at LiFePO4 acceptable voltages.
Balancing
If this battery will be connected in series, please review Dakota Lithium's Balancing Instructions.
Operating Temperature
Ideal for rugged & harsh environments. Much better than SLA or other lithium’s. -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). LiFePO4 batteries are not suitable for use in an engine compartment due to these temperature limitations.
Internal Even-Heat Technology
Increases performance in extreme cold. When charging the battery in temperatures below 0°C/32°F, the internal heating element will warm the cells to 0°C/32°F. This increases the lifespan, performance, and efficiency of the battery.
Includes Active BMS Protection
Every Dakota Lithium battery contains a Battery Management System (BMS) that handles automatic cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and high temperature protection for increased performance and longer life.
Terminals & Posts
M8 bolt terminals with hardware and automotive style SAE post adapters are included. Easy to adapt to different connection needs. (Max torque 15 ft lbs).
Marine Grade & Waterproof
Max IP65 water resistance rating. Appropriate for marine environments, not submersible.
Charger Included
A Dakota Lithium 20A charger is included. Dakota Lithium batteries like to be charged at 14.4 volts, higher than AGM or lead acid.
Certifications
All Dakota Lithium batteries are UN38.3 certified. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. Dakota Lithium is ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.
