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.




691 Watts (Wh)


F12 terminals (posts that screw in). Easy to adapt to different connection needs.


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 then a SLA 50Ah 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.

Deep Cycle Use Only

This is a deep cycle battery. Not designed for starting gasoline engines.

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.

Just got my 54Ah, for trolling motor but also have the 10Ah that I’ve used for months now on my locator. Very happy with performance of both Dakota Lithium batteries.

Russell Hayes

Want to thank Dakota Batteries again for coming through for me i appreciate what you did !

So far so good. I have made a couple fishing trips of 6-8 hours and a sand bar day of 8+ hours. While fishing 2 graphs, talon, nav lights when it got dark. Sand bar day one graph and radio and I haven’t had to charge it yet. I obviously haven’t used it a ton but so far I am impressed.

Kevin A.

I installed the Dakota Lithium 54Ah in my kayak on Monday and went out on the lake for a fishing trip. I motored around (45 lb. thrust MinnKota trolling motor) for about 4 hours…not constant use of course but a good workout for the battery. In charging it the next day with the supplied 3 amp charger it took a little less than 4 hours to bring it back to full charge. Based on my calculations that means I used less than 1/4 of the available power in this battery. I have used lead acid deep cycle batteries for decades and have never had this kind of performance! And the difference in weight (17 lbs. compared to 52 lbs.) is a such a blessing for my 63 year old self in getting out on the water.
Worth the expense in my opinion!
Many thanks!!!


Awesome battery. I have it powering a motorguide xi3 that i installed on a native titan kayak. The battery and charger are quality items and im pleased with my purchase. Thanks again Dakota Lithium

MAXIMO Salvador

Gives me more power than I need, It’s so lite my wife carries it, I love it.

William E

Well made battery, trolling motor dream. I ran for 3 hours and on my battery meter, the full charge was still flashing as I pulled my boat out of the water!!!

Anthony Thompson

I have a heavy Titan 13.5 kayak, and the 54ah Dakota battery paired with my Minn Kota will pull me all day long with power to spare! River current or calm water lakes. It just doesn’t matter with Dakota Lithium. I know go double the distance I did with my old SLA battery setup. That can make all the difference when you’re out to cash a check. Worth every penny!

Gene Minkel

Not sure which one I needed to run my Blue Sky 360 Electric Flex drive so I started with smaller one and upgraded to the 12V 54ah and could not be happier. The smaller one was returned and a credit to my account was completed in less than two weeks, kind of costly but the quality is overwhelmingly obvious in less weight and less charging.
