Specifications

11 year warranty

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

Compatibility

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

Voltage

12.8V

Energy

300 Watt-hours (Wh) per battery

Terminals

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)

Size

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

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. -20°F min, +120°F max optimal operating temps (battery performs well down to -20°F). Avoid charging below 32°F.

Discharge

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

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.

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 means that the battery systems available at Dakota Lithium are designed and manufactured to the highest ISO 9001:2015 engineering standards. In addition, quality control is completed by our US based engineering team and follows ISO 9001 standards. This added layer of safety, quality, and reliability ensures that your battery will last a long, long time.

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.

More than just a lithium battery

Kyle F.

Really good so far. These were used in my kid’s power wheels. These make the cars run super long. With daily use. My kids had well over a week in before one of them needed a charge. Sure beats the crap out of the original lead acid over priced replacement batteries! And it even blows out the motorcycle batteries that I was using prior to these! Very happy with these batteries, and very happy kids too!

Sense purchasing a Garmin Live Scope unit I’ve had issues running down my batteries. But not anymore! I purchased Dakota batteries and fished 6 hours with three Lowrance 10” units and one Garmin running and the voltage only dropped a couple tenths.The old way I would be paddling back to the ramp by then. They made a believer out of me!

Great

I HAVE ONLY USED THEM ONCE BUT SO FAR IT LASTED ALL DAY FISHING WITH MY GARMIN W/PAN OPTICS

Miles Littlefield

Batteries are awesome – they fit my applications perfectly!

I understand the Supply Chain issue of the past few months so although I am very disappointed with the order fulfillment taking so long. I can’t put too much fault on Dakota Lithium. They did try to make it up for the delays with a discount and T-shirt, but I still missed ARRL Field Day and a hunting trip where I was looking forward to trying out my radio box and portable power system. Oh, well…

Love the batteries, only have a few uses at this point. I created a battery powered carrier for my Hobie pro angler 14. Gets me up the hill easily.

Compact and light weight batteries with long lasting power ran my Panoptix no problem, all day long on the water, I’m extremely pleased with the purchase. My kayak lost 18 lbs of weight from my old battery and they were small enough to mount inside my hull,lowering my center of gravity, thanks Dakota!
