11 Year Warranty

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.

Used to build a battery pack for cpap when “off the grid.”


These batteries are awesome. I was upgraded to 2-10AH batteies because the 7AH ones were not available. Great surprise when I opened the package. Makes my project even better.

Brent Johnson

Great price for great batteries!


Dakota lithium makes a great product, and their customer service is amazing

Samuel Dodd

Dakota to my surprise upgraded my 7Ah batteries to 10Ah at no charge to me and I am extremely happy at their gesture and the performance from the pair. It is obvious that they care about their customers and the quality of their batteries. They cost a little more but are worth every penny.


Incredible customer service

Ronald Cornett

Was surprised how light the battery is. Dakota was very easy to work with

Jon R.

The batteries work great and I love the weight of them very light and long lasting. I have been using the batteries almost Daly in my garmin fish finder I put together as a ice bundle with both batteries hooked up it runs anywhere from 14 to 20 hours on one charge depending on the temperature the unit is in.

Troy Crawford

These batteries are awesome. They even upgraded me to two 10ah batteries since the 7ah were out of stock. I’m powering my DIY ammo box power station with these batteries and absolutely love it! #poweredbydakotalithium #dakotalithium #poweryourpassion
