Here at Dakota Lithium we believe quality is measured by lifespan. How long a battery lasts. The best lithium battery for you is one that gives you the power, performance and reliability to live your best life and pursue your passions to the fullest, be it cruising the open road in your RV, fishing for bass, or crossing oceans in your sailboat. Different applications require different batteries, that’s why here at Dakota Lithium we make a wide range of battery sizes so your can build the best battery system for your needs. 

Here’s 8 reason’s why the best batteries are Dakota Lithium

  1. Dakota Lithium LiFePO4 batteries will provide double the usable power and run time of lead acid. More power and run time means more time on the water or on the road without having to plug in at night. Allows for boondocking or camping off grid in your RV, fishing from sun up to sun down in your boat, or powering whatever is important to you for longer.
  2. Dakota Lithium batteries last 5X longer than AGM or lead acid batteries. Providing piece of mind and greater lifetime value. All backed up by a best in class 11 year warranty.
  3. Dakota Lithium weighs 60% less than deep cycle lead acid batteries. Less weight means more maneuverability and speed and less wear and tear on your rig. And the batteries are light enough that you can easily install and service them yourself.
  4. Dakota’s lithium iron phosphate technology works down to negative 20 degrees Fahrenheit (-29 Celsius) meaning you can travel in all seasons.
  5. The self discharge rate of a Dakota Lithium battery (i.e. how much power is lost each month the battery is not being used), is 1/4 that of a lead acid battery. That means if you take a break between adventures your batteries will still have plenty of power the next time you hit the road or get on the water.
  6. Dakota Lithium iron phosphate is optimized for solar energy with 50% more efficiency than a lead acid battery and 100% of the energy your solar panels have collected is accessible and usable.
  7. You need less batteries when you use a Dakota Lithium. Lithium iron phosphate (LiFePO4) has a flat voltage curve. That means that the voltage does not drop as you use the battery. You get all the juice down to the last drop. Historically if you power your house electronics with a deep cycle lead acid battery you would only be able to use half of the capacity of the battery before the voltage is too low to run anything. That’s why your lights dim when your lead batteries are low. With Dakota Lithium you can use all of the power of the battery, meaning that a 100 Ah battery from Dakota Lithium is equal to 200 Ah in lead acid batteries.
  8. Dakota Lithium has an 11 year warranty. That means you can install your batteries once, instead of replacing heavy lead acid batteries every few years. Giving you peace of mind and the confidence to go further, and play harder.

The Best Lithium Battery for Trolling Motors

Dakota Lithium is the leading manufacturer of high performance batteries for trolling motors. Used by top tournament anglers, Dakota Lithium batteries are optimized for electric trolling motors, providing exceptional run time and reliability in the roughest of conditions.

When choosing a lithium battery for your trolling motor look for a battery that has an Amp Hour (Ah) rating that is higher than the max amp draw of your trolling motor (max amp draw is the amps used at the highest power setting and with all features like spot lock turned on). A simple rule of thumb is: if you run your trolling motor mostly on a low setting, or for no more then half the day choose a battery that is slightly above the amp draw. For example, if you have a 12V 55 lb thrust motor that pulls 55 amps then a DL+ 12V 60Ah battery would be a good choice. If you are often out for a 12 hour day and have your trolling motor running for most of the time you would benifit most from a 12V 100Ah battery. If you run your motor at highest power level often, or fish rivers in heavy current, or your boat is larger and/or you often fish off shore, then you want twice as much Amp Hours (Ah) as your max amp draw. So a 12V 100Ah battery would be a good choice, or a DL+ 12V 135Ah battery.

Here’s a guide of what battery you need for your size trolling motor

The Best Batteries for Solar Panels on RVs & Camper Vans

Dakota Lithium batteries are the best choice if you are considering adding solar panels to your RV, Van, or trailer because they have the highest efficiency rating for solar power. That means you get more power from each solar panel, and can use more of the power you collect. A deep dive on solar power efficiency is here.

Here’s a size chart for what solar panels you need by size of RV & how many Dakota Lithium batteries you have.

The Best Batteries for RVs with Air Conditioning

Air conditioning appliances draws a lot of power and require a large battery bank when not connected to shore power. At minimum you will need 400 Amp Hours to run air conditioning in a RV trailer, Van, or Camper. The size of the vehicle you are cooling and how often the AC unit will be running determines how many batteries you will need. Please note, this assumes you are running the AC intermittently, and mostly at night. If you are camping in a very hot climate and the AC will be running more then 8 hours a day then you will need additional battery capacity to camp off grid.

Dakota Lithium’s Technology Advantage

  1. Dual Purpose Battery Management System (BMS): Every Dakota Lithium battery is built with a BMS that protects the battery from overcharging, over-discharging, short-circuiting, and high temperatures, ensuring the battery lasts a long, long time, and is safe and performs as designed. Dakota Lithium Plus batteries, like the DL+ 60Ah battery, the DL+ 135Ah battery and DL+ 280Ah battery are built with Dakota Lithium’s patented dual purpose battery management technology. Engineered for maximum reliability, and versatility, the Dakota Lithium Dual Purpose BMS provides both sustained deep cycle performance that gives steady power for a long time AND 1,000 cold cranking amps (CCA) of engine starting power. This ability to both start engines and provide deep cycle performance is the plus is the DL+ line of batteries. The best part is the Dual Purpose BMS gives not only more flexibility, but also enhances the performance of the battery in deep cycle only applications or in engine starting only applications. In deep cycle applications the battery can handle sudden amp spikes, like turning on an air conditioner, that would cause other deep cycle batteries to fail. In engine starting applications the battery uses the deep cycle capacity to provide up to 10X the number of engine starts per charge. More flexible. More Reliable. Simply better.
  2. Chemistry & Safety Advantage: Dakota Lithium manufactures exclusively Lithium Iron Phosphate batteries. Iron phosphate batteries are also called LiFePO4 or LFP which refers to the chemical makeup of the cells inside the battery. Dakota Lithium’s iron phosphate technology allows the company to engineer for an exceptionally long battery lifespan and safety, allowing for a 5 to 15 year use life depending on applications, backed up by a best in class 11 year warranty. LFP chemistry does not have oxide, preventing the possiblity of a thermal runaway that is possible with other types of lithium batteries. This chemistry safety advantage is why Dakota Lithium batteries are approved by RVIA for use in RV and homes on wheels, and the ABYC for use in boats and marine applications.
  3. Ultra-long-lifespan: Dakota Lithium’s research laboratory at the University of North Dakota, PhD scientists and engineers create new cathode and anode battery materials for use in Dakota Lithium batteries. While other battery companies are focused on light weight batteries for air planes, or drones, Dakota Lithium is focused on increasing the lifespan and reliability of Dakota Lithium batteries for use on land and water. This research has allowed Dakota Lithium to launch a series of ultra long lifespan batteries, including the Dakota Lithium 12V 280Ah battery, which has an estimated lifespan of 15 years and exceptional energy density with the usable power of six 100 amp hour group 31 marine batteries inside a Dakota Lithium battery case that is the size of one group 31 battery.
  4. Energy Density: Dakota Lithium is leading the industry in energy density by volume (watt-hour per cubic inch). Recent break throughs have resulted in the Dakota Lithium Plus 12V 135Ah battery. Built in a group 24 size battery case, the DL+ 135 Ah battery is 35% smaller in volume than a traditional 100 Ah group 31 marine battery, but has 35% more Amp Hours (Ah). When compared to a traditional group 24 lead acid battery it really shines, with 5X the usable power inside a battery that is the same size as most car batteries. Plus the Dual Purpose BMS allows for 1,000 cold cranking amps, giving you both incredible energy density and versatility.
