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) 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 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.

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.

Bottom line–great things come in small packages (45lbs lighter than my previous lead acid battery)–nothing but love for this lithium battery!! I’ve waited until going out four times before writing. I average six hour trips using a Minn Kota 55lb thrust motor on a Vibe Sea Ghost 110, running various speeds (up to 4.3mph) and my meter shows plenty of power left when I’m done. I’m confident I can stay out a heck of a lot longer without worrying about running out of power.

LOVE IT !!!!


Only used twice. Like it so far. Trolling motor seems to have more power and I’m crazy about the light weight.

Stephen Recchia

Went from 2 batteries total weight of 160 pounds to this thing at 17 pounds.
Not a fan of such a little contact area so I made 2 brass “Manifolds” for distribution.
Have 5 things to run and all on one pad was no good.
Wish I could post a pic of them.

So I waited for alittle while for this to come in, with that being said I was forced to buy a non lithium battery until this came in.
So far I’m very happy with my purchase the weight difference between a non lithium battery is incredible.
I also have the smaller battery for my fish finder and USB plug hands down the best in the Market.


The battery seems great no problems. The second time I went to charge it back up the charger just flashed the green led and did not appear to be charging the battery. I contacted customer service and they were fast to send a replacement.

I got the new charger at the house today and it doesn’t look anything like the one that came with the battery. But the one they sent me does match the picture they have displayed on their website.

Except it has test clips on the charging ends and not alligator clips the picture shows on the website. I assume this must be a refurbished charger? The test clips are too small to clamp onto the 54ah battery outside terminal posts so I have to clip them in the Allen bolt slot and the outside of the Allen bolt to charge the battery.

When the battery was charging it did seem like the negative side under the heat shrink covered area was getting warm. It might be nothing since today it was 100 degrees outside, everything was warm.

I must just be having bad luck with the chargers. I now have a way to charge the battery even if it is not ideal. It should get me thru the week long trip I have planned starting Friday. Fingers crossed.

The batteries are light compared to lead acid which are too heavy for me to move around much.

dave holmes

battery exceeds expectations, i was expecting this to last 1 hour max for trolling motor on a kayak, it lasts 2 1/2 hours minimum constant use on high speed if you stop and fish and let battery rest like normal use lasts way longer, longer than normal fishing day tested going out at 530am till 10am and in the same day without charging 3pm till 830pm. very happy with the battery, shipping took longer than i thought but i’m not going to hold the companys accountable for that these days everything takes longer so not a big deal still got battery before fishing season really got good

Absolutely awesome, worth every penny if your outdoor activities require dependable long lasting battery power!
