Dakota Lithium | 72V 55Ah Deep Cycle LiFePO4 Battery
Built Dakota tough, this single 72V (volt) 55Ah (amp hour) battery will power your passions from morning to night. Engineered with Lithium Iron Phosphate (LiFePO4) technology this battery has three times the power, one third the weight, and lasts 5 times longer than a set of lead acid batteries – providing exceptional lifetime value. Built as a drop in replacement for 72V electric vehicles, 72V golf carts, and 72V electric outboard motors.
The exceptional energy density makes this an excellent choice for vehicles where weight is at a premium — one single 72V 55Ah Dakota Lithium battery weighs 1/5 as much as a set of lead acid batteries. Enjoy increased performance, speed, and handling for 72V golf carts, people movers, and neighborhood electric vehicles. Free 72V LiFePO4 battery charger included.
To increase your driving range link multiple units in parallel. For vehicles with higher amp motor controllers two or more batteries may be required. For motor controllers with 100A-250A two units are recommended. Motor controllers with 250A-350A three units are recommended. For example, an EZGO 72V Freedom has a 350A motor controller and requires 3 units in parallel. Most 72V golf carts can fit 3+ units in the battery compartment. For other electric vehicles measure the size of your battery compartment and compare to the length and width of the battery.
Exceptional reliability with 5X the lifespan of traditional lead acid or AGM batteries. Backed up by a best in class 11 year warranty. Go further, play harder, and last longer with Dakota Lithium.

Experience the Dakota Lithium Difference
The DL 72V 55Ah battery is built with Dakota Lithium's legendary LiFePO4 cells. 3,000+ recharge cycles (roughly 8 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.
Features / Specs
11 YEAR WARRANTY
World beating, best in class, eleven year manufacturer defect warranty.
STORAGE CAPACITY
55 ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 55 ampere 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.
VOLTAGE
72V (not intended for wiring multiple batteries in series, 72V systems only). Can be wired in parallel up to 10 units.
ENERGY
3,960 Watts (Wh)
TERMINALS
M8 bolt size. Easy to adapt to different connection needs. (Max torque 15 ft. lbs.)
SIZE
20.5” x 10.5” x 8.62 ” (521x 268 x 219 mm)
WEIGHT
88.1lbs (40Kg). That's 75% lighter then a lead acid 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.
DISCHARGE
60A max continuous, 120A max 30-second pulse. For motor controllers with 100A-250A two units are recommended. 250A-350A three units are recommended.
CHARGE
30 max, 84V max recommended. Included is a 72V 10A LiFePO4 compatible charger (5.5 hour charge time).
INCLUDES ACTIVE BMS PROTECTION
Contains a circuit that handles cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and high temperature protection for increased performance and longer life.
CERTIFICATIONS
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.
ISO 9001:2015 CERTIFIED
Dakota Lithium is ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.

FAQ
Twice the power?
Yes! Here at Dakota Lithium we build all of our batteries with lithium iron phosphate technology which has many distinct advantages over traditional batteries. Including 60% less weight, a charging speed that is up to 5X faster, and a significantly longer lifespan (5-10 years longer on average). One of the most noticeable advantages however is the flat voltage curve. Unlike a lead acid battery where the voltage drops as you use the battery a Dakota Lithium battery has a steady voltage for 99% of the battery's charge. That means you get all the power down to the last drop and double the usable power of traditional batteries.
Are Lithium batteries safe?
Dakota Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries will not explode or catch fire. In addition, each Dakota Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so don't submerse the battery). For best performance & reliability we recommend using a LiFePO4 charger.
How do I charge a lithium battery?
Dakota Lithium batteries perform best when charged by a lithium compatible charger. Lead acid or SLA chargers, on-board chargers for AGM batteries, or other non-lithium chargers will charge a Dakota Lithium battery but only to 70-80% of capacity. This is because Dakota Lithium iron phosphate (LiFePO4) technology charges and is full at a higher voltage then traditional batteries (Dakota Lithium charges at 14.4 Volts). Chargers with a lithium battery setting or designed for lithium will charge at the appropriate voltage. See our full catalog of LiFePO4 battery chargers here. All batteries 54Ah and larger include a free LiFePO4 compatible charger. For troubleshooting tips download the Dakota Lithium battery user manual here.
Will cold weather affect my battery?
Your Dakota Lithium battery will discharge normally between a range of -20F and 120F (-29C to 49C). DL batteries are commonly used among ice fishers for their flashers and ice augers, so they are quite resilient and are frequently used in cold climates. In cases of extreme cold however, it is recommended that the batteries be insulated. We also do not recommend charging our batteries below freezing temperatures. If you are planning to regularly charge your battery below freezing temperatures we recommend the DL+ 12V 135Ah battery which has an internal heating element and is optimal for use in cars, trucks, RVs, off grid solar, and any application where the battery will be charged regularly in extremely cold environments (like a North Dakota winter).
Can I use this to start my car/boat engine?
Our DL+ line of batteries have 1000cca of engine starting power plus the same legendary deep cycle capabilities of all Dakota Lithium batteries. That means you can use them for starting a boat, car or truck engine. Our standard deep cycle batteries do not have this cold cranking ability and can not be used for a starting battery.
What Trolling Motor Battery do you recommend?
Dakota Lithium is a proud sponsor of over 200+ professional athletes in the fishing industry. Here's batteries sizes recommended by our pros depending on the size of your trolling motor: Motor Thrust / Max Amp Draw (A) @ Voltage (V) / Recommended Battery
What battery do I need for my RV or Camper Van?
The industry standard house battery size used in most RVs, Campers, and #VanLife builds is the DL 12V 100Ah Battery. This is a drop in replacement for AGM and most lead acid batteries. If you are charging off your engine's alternator we recommend a Victron DC-DC smart charger. If charging off solar panels we recommend a Victron Smart Solar charge controller, or if you have a solar charge controller choose the lithium setting. A handy size chart for number of batteries needed by size of RV is available here.
