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 400 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 environmental operating temps


Standard F2 terminals (6.35mm or 0.25" wide)


20 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 temperature protection for increased performance and longer life.


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

My Vex 28 now weighs 3.5 pounds lighter!! Lasts longer between chaeges than my old battery.

Darin Johnson

I bought 6 of the 12V 7AH batteries because I was tired of buying lead batteries that only last maybe a year. The Dakota Lithium batteries out performed my previous batteries on the first ice fishing trip.

David C.

We have 4 of the 7Ah batteries for our ham radio GO kits. Beats the old AGMs.

Norman Brisson

These batteries are are so far proving to be great as I use them on my scooter and being Lithium is a bonus being light, you see I use my small scooter to propel me combined with my walker as I have MS pulling me on the school’s inside corridors simply very glad making the purchase.

We upgraded my Daughters electric Dirt Bike! See the results on her YouTube Video
