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 100-120VAC, 50/60HZ. OUTPUT: 14.4 volts, 40.0 amps, 10 amps per bank / channel

Terminal Connections

SAE 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 SAE 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.

How fast will my battery charge?

Charges at a rate of 10 amps per battery (4 batteries supported). To determine your charging speed take the amp hour rating of your battery and divide by 10. For example, a 54 amp hour battery (Ah) would charge in 5.4 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 20 amp charger with a 23 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.

Suitable for:

  • Marine onboard charger
  • Charging multiple 12V batteries
  • Charging any lithium battery
  • Optimal for batteries >20 Amp Hours
  • Onboard charger installed on a boat, RV or Golf Cart
  • LiFePO4 Compatible Charger
  • Lithium Titinate Oxide (LTO) Battery Charger

Mike was a great help and answered promptly. Just wish Dakota made a dual 12V charger.

Tim Champlin

Well built charger

Arie Rosado

Really nice to charge each battery individually. Now I know they are all fully charges and not unbalanced.

John Y.

I use this charger to make sure that all of my batteries have equal charges on them. It is very easy to use.


Very well packaged for shipping. Works as described on Dakota website. Very pleased so far.
