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.

So the 12V54Ah is my 4th purchase with Dakota and I use it for my small jon boat 12V Minkota. Exactly what I expected gives me full power for about 6 hours against strong current. Awesome products.

The battery is awesome and lasts a little longer than expected. If the review was solely on the performance of the battery it would be a 5/5 the issue I had was with the install. I have Livescope LV 34 running on a 1022, 2x helix 10SI, a Rapala aerator, and a single moon light. I can run two of the graphs at the front with the aerator and get a 10hr day easy. I do put them in sleep mode when not using. Example when I’m running down the lake the garmin and front helix are asleep. When I get The the spot I put The helix at the console in sleep mode. I would Run them all to find out what the true limitations are, however I get Interference between the two helix’s. As far as charging It has taken at the max about 2.5 hours to be topped off. My only complaint is the bolts that come with it. They send a small set of you have a single or 2 connections to go to each post or a super long one. I had to go get something in the middle because I have 5 connections going to each post. Be attentive to the specs online and with the charger, kind of wish they would throw a card in with the bolts as a reminder instead of having to look it up or on the install/information card. The specs, specifically on tightening the posts and the charge states to not keep it continuously hooked up after fully charged, recommended to unhook after 16-24 hours after charging is complete I feel like most people would over look that. So because of that and having an older boat I had install switches to ensure everything is off. I have a TH marine 24 series mount for it. I cut wood with holes to make a snug fit and ensure airflow.

Powers two Garmin UHD 93 SV’s and livescope for days! Love it! Will be buying another DL for my trolling motor soon.

Used my new 12V 54Ah Dakota Lithium battery for the first time yesterday. It pulled my 16 foot boat around for 5 hrs and I still had 3/4 charge left on it. Very happy with the battery so far.

Wonderful power and stamina!




I love this battery. I am thinking about getting 100ah
