For 12 volt lithium batteries

We highly reccomend 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, 3.0 amps

Terminal Connections

Alligator clips for ease of use. Clip black to your black terminal. Red to your red terminal. Do not short circuit. 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.

How fast will my battery charge?

Choose a 3 amps. To determine your charging speed take the amp hour rating of your battery and divide by the amp rating of your charger. For example, a 3 amp charger would fully charge a 7 amp hour battery (Ah) in 2.3 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 10 amp charger with a 10 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 Dakota Lithium (LiFePO4) batteries. This charger charges at 14.4 volts.

What is the difference between a 3 amp and 10 amp charger?

The amp rating is how much energy goes into your battery in 1 hr. For example, a 10 amp charger will charge a 54 amp hour battery in 5.4 hours. An appropriate sized charger should be 1/3 of less the amp rating of your battery. For example, a 3 amp charger is perfect for a 10 amp hour (Ah) battery.

Suitable for:

  • Charging 12v batteries
  • Compatable with all 12 volt Dakota Lithium Batteries
  • LiFePO4 Compatible Charger
  • 3A (amps) size is optimal for batteries <25Ah
  • Choose the 10A (amps) charger for batteries >25Ah

Good fit charger for the batteries that I got don’t know how it works yet because the batteries came fully charged

Daniel Rollings

Dakota is amazing. Nice chatting with you at the SP Ice show

Rudy Nix

Originally sent the wrong AC cord (European instead of US), but as soon as informed, sent out the correct one very quickly


I have been using Dakota Lithium batteries and accessories for a couple years now. They are light and durable, i have had no issues in the field yet. If you order in bulk as i do the price is amazing for these models. Very Happy

Gary B.

Works beautifully!

Recharged my batteries in short order, but not happy with the alligator type clips. Not very secure and they pop off real easy. I’m exploring a way to mount them in the battery compartment and connect them to the batteries with rings to the posts. I have been in contact with Adam, he has been extremely helpful.

Andrew Laluk

Charger seems to work great and was easy to adapt to speaker box plug in. Ripped out old charger for lead acid battery was easy and like the led from red to green to know when it’s charged.

Daniel Wyman

Very easy to use .
