11 Year Warranty

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


5.94"x 2.55"x 3.74" (151x65x95mm). Replaces UB1280 battery and many others.


2lbs 2oz (1.30Kg). That's 60% lighter then a SLA battery.


14 ampere hours (Each battery is 7ah). Dakota Lithium batteries provide consistent power for all 14 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.

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. Charging 32'F to 120'F.


Standard F2 terminals (6.35mm or 0.25" wide)


10 A max continuous, 50 A max 300 mS pulse. 9.0 V max discharge, 11.0 V max recommended discharge. For longest lifetime recommended discharge rate 1-5 Amps. The flat discharge voltage curve provides a 75% bigger capacity then a SLA 10Ah battery.


10 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.


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.


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

  • Hiking, Camping, & Outdoors
  • Replacement for SLA 12v
  • Fish finders & Flashers

Dakota Lithium makes some of the best batteries on the market. Outstanding performance, exceptional customer service, best in the business! Prime example of, “you get what you pay for!”

John Piskorski

Great deal on two batteries.

William Chopak

Even though they are bulkier than my previous 24 vdc Lion EBike battery pack from Clean Republic, they seem to be superior in range, but they are still new. Time will tell.


The batteries work well.

I am gradually replacing gel lead acid batteries. I would like hints on how to safely charge with existing charge circuits.

Customer service is top notch

Purchased for my ice fishing electronics. Haven’t used them, as it’s mid summer, but when season arrives, I’ll put them to the test and let you know. I ordered the 7Ahr but those werent available, so I was upgraded to 10Ahr batteries. I was amazed when I read the note upon their delivery. Amazing business and ill definitely be back when I need other batteries.


So far so good! Perfect drop in replacement for the lead acid batteries that came in my son’s Kuberg electric minibike. Kudos to the Dakota team for upgrading my order free of charge to higher AH batteries due to shipping delays on the ones I ordered! I received the order in about 2 days after ordering (in CA). I will definitely order from them again!

Billy Rond

Great batteries.
