Storage Capacity

54 ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 100 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.


12.8V (Dakota Lithium 12V batteries can be used in series for up to 48V systems)


691 Watts (Wh)


F12 Terminals (posts that screw in) with M6 post bolts included. Easy to adapt to different connection needs. (Max torque 15 ft. lbs.)


9.01” x 5.43” x 8.38” (229 x 138 x 213 mm)


17.6 lbs (8 Kg). That's 60% lighter than a SLA 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 operating temps (battery performs well down to -20'F). Avoid charging below 32'F.


50 A max continuous, 100 A max pulse 10 second pulse. The flat discharge voltage curve provides a 75% bigger capacity than a 54Ah SLA battery.


25 A max, 14 V max recommended, 15 V max. Included is a LiFePO4 compatible charger.

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.


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, train, & marine transport.

Experience the Dakota Lithium Difference

The DL 54Ah 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.

have 2 54ah Dakotas in series for 24 volt Minn Kota Ulterra works great plenty of power usually fish 2 days before charging . Really like space and weight saving from these batteries

John G.

I got 2 of these 12v 54ah batteries for my flats boat. I have a Minnkota rt70 trolling motor that I use when I’m bass fishing in tournaments.
I put them to the test on Lake Okeechobee for my bass club 2 day tournament. It was super windy and I was fishing though the thickest vegetation. My trolling motor had full power all day! 7 to 8 hours of hard use and they worked awesome! Not to mention the bow of my boat is over 50 pounds lighter. It took about a week to receive the batteries after a placed the order. I’m very impressed with the customer service and the products. I would highly recommend Dakota Lithium to anyone thinking about getting lithium batteries. I’m going to get a starter battery next!


Used this for my new Texas Power Paddle kayak motor- gave me excellent performance for almost three straight hours on high!

Harvey Houck

Battery arrived as advertised. Well packaged, charged to extent advertised. Have not installed in my kayak yet, but the bench test with the motor was successful. Sales team promptly and satisfactorally responded to a couple of questions I posed prior to receiving the battery. Printed information included in the package answered any lingering questions I had. I’m totally satisfied with my dealings with Dakota and would recommend them to any one interested in adding power to a kayak. Now where do I find a battery box custom sized for my battery?

Pete S.

I have not had a chance to use the battery yet and probably will not be able to until spring of 2022. However, I can comment on the weight of the battery. Compared to my other marine battery it’s so nice not to have to pick up a batttery that weighs 60lbs compared to the lithium that weighs just 17lbs. I’m so looking forward to trying out the new lithium battery next year. I would probably rate the battery a ‘5’ but only gave it a ‘3’ because I have not used it yet.
