Features

HALF THE WEIGHT. TWICE THE POWER.

All Dakota Lithium batteries are engineered with Lithium Iron Phosphate technology (LiFePO4) providing long lasting performance in the harshest environments. Allowing you to go further, last longer, and play harder.

11 YEAR WARRANTY

Dakota Lithium offers a best in class 11 year pro-rated warranty on all of our batteries.

BATTERY MANAGEMENT SYSTEM (BMS) - Ensures safety and long battery lifespan

All Dakota Lithium batteries include an active BMS protection circuit that handles cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and temperature protection for increased performance and longer life. Safety measures provided by the BMS prevent overheating. All Dakota Lithium batteries have a BMS that can support linking batteries in series or parallel.

LITHIUM IRON PHOSPHATE - LiFePO4

Different Li-ion batteries use different chemistries. Dakota Lithium exclusively engineers our batteries using lithium iron phosphate or LiFePO4 for short. Lithium Iron Phosphate batteries are the safest lithium battery chemistry. Unlike the cell phone battery in your pocket, or the laptop battery on your desk, the structural stability of LiFePO4 results in significantly less heat generation compared to other lithium chemistries.

NO THERMAL RUNAWAY - Dakota Lithium cells do not produce oxygen

The main cause of fire or explosion of a lithium ion battery is due to the cells being compromised or ruptured, which causes thermal runaway. Without proper management, thermal runaway may result in fire. Dakota Lithium LiFePO4 is extremely stable and does not produce the oxygen needed to aid thermal runaway and unlike other lithium battery chemistries will not result in a catastrophic meltdown.

100% COBALT FREE - No rare earth elements

NCM and other lithium ion chemistries that contain rare earth elements such as Colton or Cobalt produce oxygen and toxic fumes when ruptured, leading to fire. Dakota Lithium does not contain rare earth elements, and does not produce oxygen or is prone to fire.

CERTIFICATIONS - Tested and certified for safety and reliability

Dakota Lithium batteries meet U.N. 38.3 standards and built from grade A cells. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. UN Manual of Tests and Criteria certified, and meets all US & International regulations for air, ground, marine, and train transport. Dakota Lithium is ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.

IEC62133 certifications and additional laboratory services are available as required by our OEM clients.

INSTALLATION & CARE - Treat your batteries right

When proper installation and battery care is followed, your LiFePO4 battery will be safe and reliable for many years. This includes making sure all connections are tight and proper wiring sizes are used, compatible chargers and charging components are used, and the batteries are used for purposes that they are designed for.

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. All batteries 54Ah and larger include a free LiFePO4 compatible charger.

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 cannot 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

• 25 lbs / 25A @ 12V / DL 54 or DL+ 60
• 30 lb / 30A @ 12V / DL 54 or DL+ 60 or DL 100
• 45 lb / 42A @ 12V / DL 54 or DL+ 60 or DL 100
• 55 lb / 50A @ 12V / DL 54 or DL+ 60 or DL 100
• 70 lb / 42A @ 24V / 24V Single or DL 54 x 2 or DL+ 60 x 2 or  DL 100 x 2

• 101 lb / 46A @ 36V / 36V Single or DL+ 60 x 3  DL 100 x 3 or DL 200 x 3
• 112 lb / 52A @ 36V / 36V Single or DL+ 60 x 3 or DL 100 x 3 or DL 200 x 3
• >112 lb / Up to 100A @ 36V / DL+ 60 x 3 or DL 100 x 3 or DL 200 x 3

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 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.
