Specifications

11 Year Warranty

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

Capacity

20 Ampere hours. Dakota Lithium batteries provide consistent power for all 20 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

256 Watt-hours (Wh)

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.

USB / Voltmeter

USB B & C ports provide easy charging for personal electronics. Voltmeter included for monitoring battery power levels.

Size

6.3" x 3.94" x 3.86" (160mm x 100mm x 99mm)

Weight

4.25 lbs (1.93Kg) That's 65% lighter then 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

Please note: For small trolling motors <20 lbs of thrust, we recommend using two of these batteries in parallel to create a 40 Amp continuous discharge rate and 40Ah of capacity. This increases runtime and lifespan of the battery.

Charge

10A 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.

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 80Ah parallel)

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 ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.

Charger Sold Separately

This battery should be charged using a LiFePO4 compatible charger. Dakota Lithium 12V batteries should be charged at 14.4 volts. Lead acid chargers will work, but will only charge the battery to 80% of capacity.

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
  • 6-dzm-12 battery equivalent
  • 12V 12Ah SLA Equivalent Size

Experience the Dakota Lithium Difference

Engineered in a 12Ah SLA case, but with with 20Ah of Lithium Iron Phosphate (LiFePo4) technology this, battery has three times the power, half the weight, and lasts 8 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.

so far so good

This is my third Dakota Lithium battery. I have loaned one of my DL batteries the last two weekends to people with lead acid batteries that died. Great batteries, power my camera and power box and depth finder. Looking forward to powering my Lowrance Active Target.

Used it a couple of times so far only but it has been great. Used it on livescope with 9 in screen for ice fishing. Had it on from about 6:30AM-4:30PM. I did turn it off when we eating for about 30-45min. It lasted the whole time. I am not sure how much battery was left as I just charged it again when I got home but that is still about 9-10hrs that I can depend on for a day of ice fishing. You may not even have it on that much, I just wanted to try and test it out. Had back light on auto to adjust a little throughout the day instead of full 100% on so that saves a little energy too maybe. Overall great so far plus an 11 year warranty

Marilyn Harvot

Put it in Garmin panoptics perfect size

Josh H.

So far so good.

Sean F.

Awesome battery, lasts SO much longer than anything I’ve used before

Richard

Absolutely great so far … ask me again i five years or so and I can provide a meaningful review. Thanks.

Pat G.

Quickly shipped during the busiest time of the year. I love being out ice fishing and seeing the voltage hold steady on the Garmin Panoptix!

STEVE F.

An excellent battery for portable field operating with my Yaesu FT817ND…better than expected, an outstanding value.
