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

Dallas Ingersoll

charges the battery, as expected…

I had dead renogy 50ah. I ran it out on a 12v fridge freezer. The volts were .012 or something. BMS low cut off. I tried to charge it back up with my solar panel and charge controller, but it wouldn’t turn back on. No one was sure if this little unit would bring it back to life. But it did! 🙂 Great little charger for LiFePo4 s . charged it up to 14.13v Love this! Highly recommend this as a way to save your day.

Very nice charger

Bought three 12v 10Aa batteries and am using them to power 12v electric water pumps for irrigation at our farm. We have three stations with 350 gallon water containers that we fill up from a lake about 200 feet away using gas powered transfer pumps. Then the 12v Dakota batteries do the job of powering smaller pumps that provide great water pressure at the irrigation hoses. Right now I can get through three days worth of watering before recharging with this charger, so I rotate the batteries as needed. The charger works great and I like that it has a light indicator to let me know when it is fully charged. However, our next step will be to hook up solar recharging panels so that the system is perpetually ready to go. At that point, I will mainly use this as a backup charger when needed.
