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.




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.


65 lbs (29.5Kg)


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.


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.


<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.


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.

Suitable for:

  • Boating & Sailboat Batteries
  • RVs
  • Off grid energy storage
  • Vans & Campers
  • Home energy storage
  • Solar storage
  • DIY Powerwalls
  • Emergency power
  • Golf Carts (125 - 200 mile battery range)
  • Neighborhood Electric Vehicles (NEV)

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.

Great battery

Art C.

I have only had my Dakota Lithium 277Ah battery for several weeks, but my experience working with the team at Dakota and their products has been wonderful. Their support team was very helpful in answering my questions prior to my order, making sure that the battery and the DC-DC charger would work with the solar system I had just installed on my RV. More impressive than that, was the support I received when I had an issue during shipping which was not even Dakota’s fault. They resolved my problem quickly and I have been 100% satisfied. I’ll write another review after I get a little more experience with the battery but it has performed beautifully so far.
