25 Ampere hours. Dakota Lithium batteries provide consistent power for all 25 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.




300 Watt-hours (Wh)


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


M6 terminals (posts that screw in). 2 sided terminal block allows for side or top installation. When used in salt water environments we recommend applying a small amount of dielectric grease on top of each terminal after installation. It helps extend the lifespan. (Recommended Torque 5 ft lbs, Max Torque 9 ft lbs)


7.125"x 3.03"x 6.69" (181x77x170mm)


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

Lifecycles (battery lifespan)

Up to 80% capacity for 3,000 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.


30A max continuous, 300A max pulse (<5 sec). The flat discharge voltage curve provides a 75% bigger capacity than a 25Ah SLA battery. Please note: a single battery is only appropriate for trolling motors with <20 lbs of thrust. For trolling motors with 20 to 45 lbs of thrust a single DL 54Ah battery is required. Or you can combine two batteries in parallel to create a 50 Amp continuous discharge rate and 60Ah of capacity. This provides the amps necessary to run the larger motor, increases runtime and lifespan of the battery.


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.

Drop in Replacement

Replaces size UB12180, size FM12180, and size 6fm18 SLA batteries with twice the run time and half the weight


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

Dakota Lithium is certified by ISO 9001:2015 for lithium battery engineering, manufacturing, and quality control. This meaDakota Lithium is ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.

Smart Dual Purpose BMS

Optimizes battery for use in both deep cycle applications and engine starting applications and allows for the battery to be charged by a power sports, tractor, ATV, or UTV engine alternator.

Suitable for:

  • Fish Finders, Flashers, & Boating Electronics
  • Humminbird Fish Finders
  • Garmin Livescope (4 hr run time - use the 46Ah battery for full day)
  • Ice Fishing
  • LiFePO4 Replacement for SLA 12v
  • All Terrain Vehicles (ATVs and UTVs)
  • ATV, UTV and Portable Electric Winches
  • Starting small engines (for cars / boats / trucks use the DL+ 135)
  • Lawn Tractors & Ride of Top Lawn Mowers
  • Emergency jump start for outboard motors
  • Industrial Batteries
  • Solar Lighting
  • Robotics
  • Hiking & Camping
  • Remote Power
  • Outdoor Adventures
  • Mobility Scooters
  • Motorcycles (confirm your battery dimensions match before order)

Experience the Dakota Lithium Difference

The DL 25Ah battery is built with Dakota Lithium's legendary LiFePO4 cells. 2,000+ recharge cycles (roughly 5 year lifespan at daily use) vs. 500 for lead acid or AGM. Optimal performance down to minus 20 degrees Fahrenheit (for winter warriors). Plus twice the power of lead-acid batteries at half the weight.

Great so far

Bill T.

I wish the battery had traditional terminal blocks. The small screw terminals on my Dakota 12 V 23 AH battery were difficult to connect to the camper’s wiring.
Otherwise the battery ran our lights, water pump and furnace for our small pickup camper for 3 days and 3 nights which the lead acid batteries struggled to do.

I recently installed a Garmin 93sv with a Panoptics transducer. I found out quick that it was a power hog. I connected it to a used separate lead acid battery which charged and tested good with a load tester. It would last 4-5 hrs. I replaced that battery with a Dakota 23 AH and before I installed it I got worried that it would not last long either, but to my surprise, it lasted all day. As a matter of fact, I intentionally left the depth on to see how long it would last with the constant drain. It lasted approximately 11 hrs which is way more, than a typical fishing day.


Awesome battery, plenty of power in a small package!!


Very happy with battery performance. Using it to power a Garmin Echomap Ultra and Livescope transducer mounted at front of boat. Very light and compact. I have used it for 4 hours at a time so far with not problems of insufficient charge.

lee penn

only used it one time so far but everything looks good small and light.time will tell how good this battery is.

Denis Potvin

Not in use yet,not before may 15th. But I have heard great things about these batteries.

Don Marshburn

great battery. contacted tech support and staff was very helpful

Brent B.

Will be very happy when I can go across the border to pick it up. Strange times we are in. Purchased another one in Canada and have been using for a few weeks and it works great!
