Best in Class 11 Year Warranty. That is 10 years more warranty then most lead acid batteries.

Storage Capacity

280 Ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 280 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




12.8 Volts (Dakota Lithium 12V batteries can be used in series for up to 48V systems)


13.31"x 7.24"x 10" (338×184×254mm). Height is to the top of the terminals.

Group Size 31 & 8D

Group Size 31 and Marine 8D size compatible


65 lbs (29.5Kg)


Up to 80% capacity for 4,000 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.


200A 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.


<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. Even heat technology allows for charging below 32'F. Internal even-heat technology allows for charging below 0°C/32°F

Operating temperature

Ideal 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..


Increases 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 & 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.)

Marine Grade & Waterproof

Max IP65 water resistance rating. Appropriate for marine environments, not submersible.


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.

Free LiFePO4 Charger Included

12V 20A charger included ($299 value). Dakota Lithium 12V batteries should 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 DL+ 12V 280Ah 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.

Installed 3x280ah in my Northern Lite 9-6 truck camper to support my extended winter camping.

Performance Rovers

Excellent product as always from an excellent company!

Matt Swearingen

I have not used the batteries much yet, but so far so good. I do think my hydraulics on my lift seemed to work better in the cold than they ever have powered by golf cart batteries. The specs say that 2 of these 12 volt batteries are more powerful and more Amp Hour capacity than four 6volt golf cart batteries. I am hoping they last a good long time. Customer service was top notch too.

Henry De pena

I run my 12 volt lights in Dominican Republic with solar panels. This baterry never run out of power.

Patrick Booth

I am pleasantly surprised by the power they have. I originally bought 800ah four years ago to power my yacht, and just increased the capacity to 1360ah. I can run an air conditioner 24/7 in summer in the main cabin, and still use the induction stove top.

William Roy

Such an awesome battery!! Decided to run 2 of them along with a slew of Victron products on my 26ft Sea Ray. Dakota has great customer service and will gladly accept your return if you’re not satisfied. I originally ordered 2 of the 200ah and then decided I wanted something bigger. Would highly recommend them and will use Dakota for my next project on my RV.

Larry Groupe

Absolutely love my pair of the 12v 277AH batteries! They are completely providing my off grid home with all the power I need! I have recording studio in the house which requires a lot of power and Dakota Lithium has run the gauntlet and still has power to spare!

Special thanks to Patrick Rose for answering questions and giving step by step support.

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.
