Technical Specifications:

• For 12 volt lithium batteries

  We highly recommend you use a LiFePO4 compatible charger. 12v chargers for lead acid batteries may work, but will decrease performance and lifespan of the battery.

• Charger rating

  INPUT 100-240 volts, 50/60HZ. OUTPUT: 14.4 volts, 50 amps

• Dimensions

  11.063" x 3.46" x 5.71" (281mm x 88mm x 145mm)

• Terminal Connections

  Anderson connections make it easy to connect your charger to the battery. Install the ring terminals using the bolts on your terminals. Bolt black to your black terminal. Red to your red terminal. Do not short circuit. Then connect the charger via the Anderson plug when you need to charge. Red light on the charger will turn on when charging. Light turns green when the battery is full.

• Smart BMS communication

  Charger will restart or "wake up" a Dakota Lithium BMS that has turned off a battery due to short circuit or excessive amp draw. Simply connect the charger to the battery to initiate a restart.

• Waterproof Rating

  IP67

FAQ

• How fast will my battery charge?

  Charges at a rate of 50 amps. To determine your charging speed take the amp hour rating of your battery and divide by 50. For example, a 12v 135 amp hour battery (Ah) would charge in 2.7 hours.

• Can I charge my battery faster?

  For most applications a charging time of 3 - 10 hours provides the longest lifespan for your battery. But if you have an application where you need rapid charging Dakota Lithium batteries can be safely charged in up to 1 hour (at a rate of 1C). For example, you could use a 8 amp charger with a 8 Ah battery for a 1 hour charge time. Charging at a 1 hour rate does reduce the lifespan over time. In our laboratory testing we found that the longest lifespan for Dakota Lithium batteries was at a charging speed of 0.3C or less (we recommend that the charger amp rating is 1/3 or less of the battery amp hour rating for longest lifespan).

• What voltage should LiFePO4 batteries be charged at?

  14.4 volts is recommended for 12v Dakota Lithium (LiFePO4) batteries. This charger charges at 14.4 volts.

• 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?

  We have two battery options available for starting motors: the LTO Automotive Cranking battery and the DL+ Dual Purpose line. Both are designed for starting motors, with a 1000CCA equivalent of engine starting power for boat, car, or truck engines. The DL+ line also offers our legendary deep cycle capability in addition to engine starting power. Please note that our standard deep cycle packs do not have cranking ability and cannot be used for starting motors.

• 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. A handy size chart for number of batteries needed by size of RV is available here.
