Specifications

11 Year Warranty

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

Capacity

18 ampere hours. Dakota Lithium batteries provide consistent power for all 18 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, especially in cold temperatures. You get all the juice down to the last drop.

Voltage

12.8V

Energy

231 Watts

Terminals

F2 Terminals (spade socket). When used in salt water, or corrosive, environments we recommend applying a small amount of dielectric grease on the blades of each terminal. It helps extend the lifespan.

Size

5.94"x 3.95"x 3.78" (151x99x96mm). Replaces 12Ah 12v SLA Batteries.

Weight

4.55 lbs (2.0Kg). 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

18 A max continuous, 50 A max pulse (<3 sec). The flat discharge voltage curve provides a 75% bigger capacity than a SLA 18Ah battery. Please note: For small trolling motors <20 lbs of thrust, we recommend using two of these batteries in parallel to create a 36 Amp continuous discharge rate and 36 Ah of capacity. This increases runtime and lifespan of the battery.

Charge

9 A max, 14 V max recommended, 15 V 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.

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.

Series or Parallel

BMS can support wiring these batteries in series or parallel for up to 4 units (up to 48V series or to 12v 72Ah parallel)

Certifications

All batteries are UN 38 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.

Charger Sold Separately

This battery should be charged using a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery.

Suitable for:

  • Fish Finders, Flashers, & Boating Electronics
  • Garmin Fish Finders
  • Ice Fishing
  • LiFePO4 Replacement for SLA 12v
  • Mobility Scooters (triple your battery range)
  • 24V Electric Bikes & Scooters
  • Industrial Batteries
  • Robotics
  • Hunting, Camping, and Trail Cameras
  • Remote Power
  • Outdoor Adventures

Experience the Dakota Lithium Difference

Engineered in a 12Ah SLA case, but with with 18Ah of Lithium Iron Phosphate (LiFePo4) technology this, battery has three times the power, half the weight, and lasts 4 times longer than a 12Ah sealed lead acid battery. Optimal performance down to minus 20 degrees Fahrenheit (for winter warriors). Plus a best in class 11 year warranty.

Daniel

Very lightweight and it seems to power my Garmin fish finder with plenty of run time. I run the Echomap 93 sv and usually run at least traditional sonar with down imaging, and often run both of those also with side imaging. The battery performs as I expect it to and charges quickly using the Dakota lithium charger. Very happy with it.

James K.

Haven’t used them for long but they seem promising to start.

Let’s me fish all day

UNIVERSAL MITSUBISHI

GREAT SERVICE!

Greg Betteridge

This is a big step up from my 10 aH battery and I’m very pleased.

Sanjay Gokani

Amazing Battery. Very small and light and works great. Quick charge.

Doug Pravecek

Preforms great

Thomas T.

Love it.

Jeff Pope

Got this one for my kayak to run my depth finder and navigation lights. So far I’m super impressed with everything.!! Shipping was quick and on time and even got email updates on battery location and expected delivery time. I can start before sunrise and use my fish finder (hook 7 hdi) all day with no worries!!
