Specifications

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 for 24V, 36V or 48V single batteries, by request

Easily charge a 24V, 36V, or 48V single battery, or a bank of 12V + 24V or 36V batteries. (adapter available by request for no additional cost)

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.

Lead Wire Lengths

Charger to SAE plug 36"
SAE to ring terminals 24"
Total length connected 60"
AC Power Cord to Charger 60"

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.

Waterproof

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.

Not much on disconnecting every time you’re done, charging the batteries and discharger bleeds back

Thomas Bates

Havent used this yet either but it came with 24v adapter so that was nice. We will see how it works

Ed C.

So far so good, charging (3) 12v 100ah in series for 36v trolling motor, still really new but seems to be a solid brand still have some field testing to do.

Jason

Quality charger and the only thing I wish was different is charging status lights would be located on front of charger instead of bottom

Jake Wyatt

Perfect!

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
