Technical Specifications

  • 11 Year Warranty: World beating, best in class, eleven year manufacturer defect warranty.
  • Capacity: 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.
  • Voltage: 12.8V
  • Energy: 300 Watt-hours (Wh)
  • CCA: 300 cold cranking amps, suitable for ATVs, UTVs, generators and small engines
  • Terminals: 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)
  • Size: 7.125"x 3.03"x 6.69" (181x77x170mm)
  • Weight: 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. -4°F min, +120°F max optimal operating temps. Avoid charging below 32°F.
  • Discharge: 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.
  • Charge: 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
  • Certifications: 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.

FAQ
  • Twice the Power?

    Yes! Here at Dakota Lithium we build all of our batteries with lithium iron phosphate technology which has many distinct advantages over traditional batteries. Including 60% less weight, a charging speed that is up to 5X faster, and a significantly longer lifespan (5-10 years longer on average). One of the most noticeable advantages however is the flat voltage curve. Unlike a lead acid battery where the voltage drops as you use the battery a Dakota Lithium battery has a steady voltage for 99% of the battery’s charge. That means you get all the power down to the last drop and double the usable power of traditional batteries.

  • Are Lithium Batteries Safe?

    Dakota Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries will not explode or catch fire. In addition, each Dakota Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so don’t submerse the battery). For best performance & reliability we recommend using a LiFePO4 charger.    

  • How do I charge a lithium battery?

    Dakota Lithium LiFePO4 batteries perform best when charged by a LiFePO4-compatible battery charger. LiFePO4 batteries require a different charging profile and voltage requirements compared to traditional battery chargers. Chargers designed for different chemistries may work, but they may not charge a Dakota Lithium battery to full capacity. It’s important to select a charger that has a LiFePO4-compatible constant-current constant-voltage (CC/CV) charging profile, provides the correct charging voltage for your battery, does not exceed the charge current (amp) for the battery, and has a charge indicator LED to let you know when the battery is fully charged. You can find more information on How to Charge Dakota Lithium and LiFePO4 batteries on our website. If you need help finding a compatible charger for your Dakota Lithium battery, or if you want to check your current charger compatibility, please reach out to our support team.

  • Will cold weather affect my battery?

    Your Dakota Lithium battery will discharge normally between a range of -20F and 120F (-29C to 49C). DL batteries are commonly used among ice fishers for their flashers and ice augers, so they are quite resilient and are frequently used in cold climates. In cases of extreme cold however, it is recommended that the batteries be insulated. We also do not recommend charging our batteries below freezing temperatures. If you are planning to regularly charge your battery below freezing temperatures we recommend the DL+ 12V 135Ah battery which has an internal heating element and is optimal for use in cars, trucks, RVs, off grid solar, and any application where the battery will be charged regularly in extremely cold environments (like a North Dakota winter).

  • What battery do I need for my RV or Camper Van?

    The industry standard house battery size used in most RVs, Campers, and #VanLife builds is the DL 100Ah battery. This is a drop in replacement for AGM and most lead acid batteries. If you are charging off your engine’s alternator we recommend a Victron DC-DC smart charger. If charging off solar panels we recommend a Victron Smart Solar charge controller, or if you have a solar charge controller choose the lithium setting. A handy size chart for number of batteries needed by size of RV is available here.

2024/2025 Dakota Lithium Catalog

Sandra L Perzee

Quick shipping! Good product!

David P.

Got this to power my 2022 Waverunner. New lead acid batteries for it have lasted about a year and cost around $100 so the Dakota Lithium version which has an amazing 11 year warranty, and costs 2.5x the lead acid version is a great buy. It fits in the battery compartment but the elastic straps are too short since the Dakota Lithium 25aH is a little taller.

michael wiles

really like the power to size ratio!

David M.

1/2 the size ,1/3 the weight and more than double the power of the riding mower battery battery I have used for 2 years now, for on demand water and lights for camping. Loved it so much I bought a second one.

Anthony F.

Great batteries. We're using them in our two Community Emergency Response Team trailers to power local radio communications. They 25AH is a drop-in replacement for six year old 33AH SLA AGMs. They work just fine and the easy to use web site just made the whole process simpler.
