Dakota Lithium 12V/277Ah LiFePO4 Deep Cycle Battery

Experience the Dakota Lithium Difference

The 12V 277Ah battery is built with Dakota Lithium's legendary LiFePO4 cells. 4,000+ recharge cycles (roughly 5 year lifespan at daily use) vs. 500 for other lithium batteries or lead acid. Optimal performance down to minus 20 degrees Fahrenheit (for winter warriors). Plus twice the power of lead-acid batteries at half the weight.

When you go off the grid during a Dakota winter you need to be prepared for all that mother nature can throw at you. With the DL 277 Ah 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, this battery has 277 Amp Hours of capacity in a steel battery case the size of a single 100 Amp Hour. That’s 6X the amount of usable power of a single group 31 AGM battery. Built out of Lithium Iron Phosphate (LiFePO4) technology and reinforced with a ruggedized steel case, this is a battery built to last. With a lifespan of 4,000 charge cycles this battery will last up to 5 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. This is our original 100Ah battery, re-engineered with 177% more capacity in a similar sized case.

Specifications

• Warranty: Best in Class 11 Year Warranty. That is 10 years more warranty then most lead acid batteries.
• Storage Capacity: 277 ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 277 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.
• Energy: 3,545Wh
• Voltage: 12.8 Volts (Dakota Lithium 12V batteries can be used in series for up to 48V systems)
• Size & Weight: 14.6 in x 7.7 in x 10.75 in (L370mm ×W195mm ×H274mm). Height is to the top of the terminals. Handles fold down.
• Weight: 65 lbs (29.5Kg)
• Lifespan/Lifecycles: Up to 80% capacity for 3,000 cycles in recommended conditions, 70% capacity at 4,000 recharge cycles. Half-life (50% capacity) of 6,000 re-charge cycles (Typical SLA has 500 cycles). Backed up by an 11 year warranty.
• Discharge: 200 A max continuous, 300 A max 10-second 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. Included is a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery.
• Operating Temperature: Ideal for rugged & harsh environments. Much better than SLA or other lithium’s. -20'F min, +120'F max optimal operating temps (battery performs well down to -20'F). Avoid charging below 32'F.
• 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: F12 Terminals (posts that screw in) with M8 post bolts included. (Max torque 15 ft. lbs.)
• Marine Grade & Waterproof: Max IP65 water resistance rating. Appropriate for marine environments, not submersible.
• Certifications: All batteries are UN 38 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.
• Free LiFePO4 Charger Included: Free 12V 20 Amp (A) charger included ($299 value). Dakota Lithium batteries like to be charged at 14.4 volts, higher than AGM or lead acid. Lead acid chargers will work, but will only charge the battery to 80% of capacity.

Frequently Asked Questions

Twice the Power?

• Yes! Here at Dakota Lithium we build all of our batteries with lithium iron phosphate technology which has many distinct advantages over traditional batteries. Including 60% less weight, a charging speed that is up to 5X faster, and a significantly longer lifespan (5-10 years longer on average). One of the most noticeable advantages however is the flat voltage curve. Unlike a lead acid battery where the voltage drops as you use the battery a Dakota Lithium battery has a steady voltage for 99% of the battery's charge. That means you get all the power down to the last drop and double the usable power of traditional batteries.

Are Lithium Batteries Safe?

• Dakota Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries will not explode or catch fire. In addition, each Dakota Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so don't submerse the battery). For best performance & reliability we recommend using a LiFePO4 charger.

How do I charge a lithium battery?

• Dakota Lithium batteries perform best when charged by a lithium compatible charger. Lead acid or SLA chargers, on-board chargers for AGM batteries, or other non-lithium chargers will charge a Dakota Lithium battery but only to 70-80% of capacity. This is because Dakota Lithium iron phosphate (LiFePO4) technology charges and is full at a higher voltage then traditional batteries (Dakota Lithium charges at 14.4 Volts). Chargers with a lithium battery setting or designed for lithium will charge at the appropriate voltage. See our full catalog of LiFePO4 battery chargers here. All batteries 54Ah and larger include a free LiFePO4 compatible charger.

Will cold weather affect my battery?

• Your Dakota Lithium battery will discharge normally between a range of -20F and 120F (-29C to 49C). DL batteries are commonly used among ice fishers for their flashers and ice augers, so they are quite resilient and are frequently used in cold climates. In cases of extreme cold however, it is recommended that the batteries be insulated. We also do not recommend charging our batteries below freezing temperatures. If you are planning to regularly charge your battery below freezing temperatures we recommend the DL+ 12V 135Ah battery which has an internal heating element and is optimal for use in cars, trucks, RVs, off grid solar, and any application where the battery will be charged regularly in extremely cold environments (like a North Dakota winter).
