11 Year Warranty

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


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 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.


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. 5,000+ recharge cycles (roughly 8 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.

I powre my Garmin 106sv with it works great will be using it for livescope soon

Terry W.

Works great, I run 2 units from it a Carbon 9 for the 3 transducer nose cone and Elite 9 for active target

Brian H.

Powering my Garmin livescope lasts longer than I can fish in one day!!!!!


I have not used this battery yet. I bought this battery to power my Lowrance depth finder. I have heard several good things about the Dakota Lithium batteries – and decided to purchase one for my marine

Will be using this for Garmin LivescopePlus transducer and GLS10 black box with a dedicated Garmin 93sv for viewing. The battery shipped fine but was stuck in a delivery loop with UPS between Urbana, IL and Hammond, IN. According to UPS, there was a “sortation” problem that they could not explain. In reviewing the tracking log, it went between the two locations three times before it was finally delivered. I have been able to secure it in the boat, run the wiring and make all connections. Everything is getting power. I’m using the Connect-Ease trolling motor connection in lieu of a separate cutoff switch. It will likely be next month or early May before I get it out on the water to see how the battery performs. My first order was an 18amp that I use solely for a Garmin 73sv. I’ve been able to run it upwards of three days without recharging. Called Connect-Ease and spoke with the owner. He answered my questions and confirmed he had just done a similar install to the one I was contemplating that morning. My only recommendation is that the 6M studs (with washer and lock washer) could be longer as the Connect-Ease terminals are too large in diameter and need intermediate washers to make a clean connection. It would also be nice to place the charging leads jn the “battery side” of the connector to allow hooking up the charger while having the leads to the Garmin devices disconnected per Garmin’s recommendation.
