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 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.

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.

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.

I have three dakota lithium 100ah batteries to power my trolling motor and they are a game changer! I can run for days on a single charge! so i purchased this 23ah battery to run my garmin live scope it is the best performing battery on the market! If you need dependable power dakota lithium is the way to go!!

david

These are tough batteries. Plenty of amps to power my trike build in progress.

Beau

Excellent battery. I use it to power my portable ice fishing shack LED lights. Absolutely no dimming of the lights during discharge, unlike the old SLA battery which would dim whithin minutes. I’m running aprox. 4 amps of lighting 4-5hrs at a time and have yet to run out of juice. Fraction of the weight compared to my 18AH SLA. Definately notice it when walking out. Been out in temperatures from the 20’s to negative 10 so far and seen no change in performance.

Gary

I plan on using this battery in my kayak to power my trolling motor. So I ran a simple test. I powered the trolling motor with the battery after giving it a full charge. With the trolling motor suspended from a beam in my shed and the prop just spinning in air, I set the speed to the highest setting and let the motor run for 5 straight hours. Ambient temperature was about 35 deg. F. At the end of the test battery voltage was still around 13 vdc as measured by my hand held multimeter. It then took only 4.5 hrs. to fully recharge the battery. I am happy as a clam !!! Lol. Great product. Can’t wait to use it for real.

Ed

Nice size for its capacity.

JEFFERY DERIGHT

Battery size options are nice. Using my 23 for running my electronics. Been out twice and battery doesn’t even drop in voltage.
