11 year warranty

World beating, best in class, eleven year manufacturer defect warranty.


Powers all 12V electronics. Powers trolling motors 45 lbs of thrust or less. Optimal run time at 30 lbs of thrust is 100 min - 150 min depending on motor setting.

Storage Capacity

50 Ampere hours (Two 12.8V batteries to be wired in parallel). Dakota Lithium batteries provide consistent power for all 50 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

300 cold cranking amps, suitable for ATVs, UTVs, generators and small engines




300 Watt-hours (Wh) per battery


M6 terminals (posts that screw in). When used in salt water environments we recommend applying a small amount of dielectric grease on the threads of each terminal. It helps extend the lifespan. (Recommended Torque 5 ft lbs, Max Torque 9 ft lbs)


7.125"x 3.03"x 6.69" (181mm x 77mm x 170mm)


6.4 lbs (2.9Kg). That's 60% lighter than a SLA battery.

Lifecycles (battery lifespan)

Up to 80% capacity for 5,000 cycles in recommended conditions. The typical SLA has 500 cycles. Dakota Lithium batteries last so long that the price per use is a fraction of traditional batteries.

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.


300 cold cranking amps, suitable for ATVs, UTVs, generators and small engines


30A max, 14.4V recommended, 15V max. Please note: this battery should be charged using a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery. Can be charged by ATV, UTV or powersports engine alternator (<30A output).

Includes active BMS protection

Contains a circuit that handles cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and high temperature protection for increased performance and longer life.

Charger Sold Separately

This battery should be charged using a LiFePO4 compatible charger. 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.


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, and train transport.

ISO 9001:2015

Suitable for:

  • Small Trolling Motors (<30 lbs of thrust)
  • Fish Finders, Flashers, & Boating Electronics
  • Garmin Fish Finders
  • Ice Fishing
  • LiFePO4 Replacement for SLA 12v
  • Industrial Batteries
  • Solar Lighting
  • Robotics
  • Hiking
  • Camping
  • Remote Power
  • Outdoor Adventures

Experience the Dakota Lithium Difference

The DL 25Ah battery is built with Dakota Lithium's legendary LiFePO4 cells. 5,000+ 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.

I’m am well pleased with product and service.

Beth Rhoads

Finally got out on the water. I’m using the twin pak to power my Garmin Echomap 106sv on bow and on driver console. Each battery is powering and individual unit and they worked fantastically. Started day showing 13.2v and when I got home they were at 13.1v. I’m a happy customer. Thanks.

Matthew G.

Used to 12 volt 23 amp hour batteries to revive a GOGO ELITE scooter . Works great now



Steve A.

Great range on my Mobility Scooter

Virgil Huston

Haven’t used them yet, but seen them last all day on beach mining

Julio Montjoy

Best investment I have done lately, now that I am using the new lithium batteries my charging time is quicker and the batteries last a lot…………..longer than the std acid batteries.
Just wish these lithium batteries are a little cheaper to get a second set.

James Stewart

Really Good

Joseph G.

What I bought them for yhey were insufficient for.. so will be using them for projects… I need a 121R format with 660 cranking amps
