STORAGE CAPACITY

46 ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 46 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.

 

VOLTAGE

12.8V (Dakota Lithium 12V batteries can be used in series for up to 48V systems).

 

SIZE

7.6”L x 5.1” W x 6.8” H (194mm x 132mm x 173 mm). U1 size (Group 21).

 

DROP IN REPLACEMENT SIZE U1

U1 equivalent for physical dimensions & terminal compatibility. 3X the usable power of a U1 SLA battery.

 

ENERGY

552 Watt-hours (Wh).

 

TERMINALS

F12 terminals (posts that screw in) with M6 size bolts. Max torque 15 ft. lbs.

 

WEIGHT

10.5 lbs (4.75 Kg). 65% lighter than a SLA or lead battery.

 

LIFECYCLES (BATTERY LIFESPAN)

Up to 80% capacity for 6,000 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 batteries. -20'F min, +150'F max optimal operating temps (battery performs well down to -20'F). Avoid charging below 32'F. Discharge cut off at - 20'F / -20'C. Charge cut off at 23'F / - 5'C. BMS high temp cut off at 167'F / 75'C.

 

DISCHARGE

50 A max continuous discharge. The flat discharge voltage curve provides a 3X bigger capacity then a U1 SLA 35Ah battery.

 

CHARGE

Recommend for longest life 10A or less (.2C), Max continuous 23A (.5C). 14.4 V recommended, 15 V max, BMS protection from over charging will cut off at 15V. Included is a free 12V 10 Amp (A) LiFePO4 compatible charger that charges at the recommended 14.4 Volts.

 

INCLUDES ACTIVE BMS PROTECTION

Contains a high discharge capable circuit that handles cell balancing, low voltage cutoff (10V) preventing over discharge, high voltage cutoff (15V) preventing over charging, short circuit protection and temperature protection for increased performance and longer life.

 

COLD TEMPERATURE CHARGING PROTECTION

Contains a smart BMS temperature cutoff that prevents charging when cells are below 0'F/C and protects the battery.

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.
