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.

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.

The best Batteries I have ever owned

Kent K.

Light battery! Came with charger and charged without any issues. Could her the BMS running. Cool battery!

I purchased two 12v 54Ah batteries for my two pontoon boats (9foot) and am totally satisfied with their performance. We just spent the day fishing one of the high lakes in our area and are totally impressed with them. A little pricey, but would buy one again.


Your products are all 5 stars and your customer service is top notch. I recommend your products to everyone.

After using a traditional lead acid battery to power my trolling motor, I finally decided to make the investment in a light weight LiPo battery. My first option was an expensive unit from Cabelas. The salesperson was of no help and I still needed an additional charger, a nearly $800 investment. Then, I discovered Dakota and contacted Patrick in their customer service dept. After determining my needs, he recommended a 54Ah battery that came with a charger for a total of $499. Thanking it a step further, I run a Garmin fish finder and often use it in a non motorized belly boat. For this purpose, Patrick recommended the Dakota 10Ah battery, smaller and lighter than an old-fashioned 6v flashlight battery. I added a smaller charger (not included in the $100 battery price) Both batteries charge in less than 3 hours. I have only used the pair of batteries on one occasion, using the trolling motor, on and off, for perhaps 5 hours. The fish finder was on for nearly 6 hours. It is difficult to measure how much power is left in a LiPo battery after use but I never had concern that either battery was at risk of running out of power.

I would recommend Dakota, their products and their very helpful staff (specifically Patrick) to anyone considering the upgrade to LiPo batteries.


Perfect for fly fishing pontoons

Tim was so helpful while I was making my decision on which Dakota battery I would need. He answered all of the questions that I threw at him. So far I am very pleased with my 12V54AH Deep Cycle battery. Charged it upon receipt and have logged about 4 hours use on my Minn Kota 55 trolling motor and it still shows a full charge!! Awesome product.
