11 year warranty

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


Powers all 12v electronics. Powers trolling motors 45lbs of thrust or less. Optimal run time at 30lbs of thrust is 100 min - 150 min depending on motor setting.

Storage Capacity

46 ampere hours (Two 12.8V batteries to be wired in parellel). Dakota Lithium batteries provide consistent power for all 46 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.




295 Watts x 2 batteries


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)


181mm (L) x 77mm (W) x 167mm (H)


6.4 lbs (2.9Kg). That's 60% lighter than a SLA battery per battery.

Lifecycles (battery lifespan)

Up to 80% capacity for 2,000 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 discharging temps (battery performs well down to -20'F). Charging 32'F to 120'F. (charge above freezing)


48 A max continuous, 120 A max pulse (<3 sec) when wired in parallel. The flat discharge voltage curve provides a 75% bigger capacity than two 23Ah SLA batteries in parallel.


12 A max, 14.4 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.

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.


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.

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 23Ah battery is built with Dakota Lithium's legendary LiFePO4 cells. 2,000+ 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.

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!

David H.

Have only used once for half day of kayak fishing, using for trolling motor and pulling another kayak for part of the trip. Only ran down to 90% charge. Will probably only use single battery next time.

Dan Mehren

Love the products, love the service. Wouldn’t go anywhere else.

Charles Coburn

100% pleased. Thanks to all the helpful knowledge that they provided. I highly recommend Dakota Lithium

Ryan Garcia

Solid product. The warranty is definitely worth it.
