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.

Free Adapter kit for 24V, 36V and 48V batteries

Easy charge 24V, 36V, or 48V single batteries or a bank of 12V + 24V or 36V batteries.

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.


Built for marine use. IP 67. Internal components are sealed in a waterproof putty that makes it impossible for water to short circuit the charger. Wiring is SAE waterproof plugs.

Richard Schwalbach

Easy install; way sufficient cable length to reach all 4 batteries. Initial charge (batteries arrived at only 5% charge) made the unit super hot so upon install I used 1″ stand off mounts so that air can circulate fully around the charger. Appreciated receiving the remote chargers for all the batteries, but this is the only way to go to insure a complete charge and balancing.

Scott Gibson

so far so good. Nice size and weight

Michael Henry

You had to replace first one in a short period of time I used it.but the replacement has been great so far.if you could I would be interested in what went wrong with product or if you upgrade please reach out.Thnk you.

Paul A.

Small profile, long leads made install location easy. Great charger for multiple batteries.

Dan Trippeda

I love my on board charger it works great.

Timothy Smeal

Installed on Ranger BassBoat. Love it! Fast charging! Initial charge on batteries caused charger to put out an abnormal amount of heat. Used the next day to charge batteries and no abnormal heat conditions existed.
