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.
INPUT 100-120VAC, 50/60HZ. OUTPUT: 14.4 volts, 20.0 amps
Anderson SB 50 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 Anderson plug when you need to charge. Red light on the charger will turn on when charging. Light turns green when the battery is full.
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.
Charges at a rate of 20 amps. To determine your charging speed take the amp hour rating of your battery and divide by 20. For example, a 54 amp hour battery (Ah) would charge in 2.5 hours.
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).
14.4 volts is recommended for Dakota Lithium (LiFePO4) batteries. This charger charges at 14.4 volts.
A 10 amp charger is included with every Dakota Lithium 54Ah and 100Ah battery purchase. This charger is an add-on and charges twice as fast. Great for RVs, Boats, Solar, or other applications where you need to charge your batteries as fast as possible.
Very pleased with the 12v 20Amp charger. It charged my DL+ 135Ah battery quickly and efficiently. My only request would be for it in an on-board weatherproof version for more convenience.
Works perfect and fast!
As you might expect only one charge do far. Perfect, quality charger!
Great product and a good aggressive company
Charger worked great . Would have purchased at least a 200 Ah battery if you could ship using OTHER THAN FEDEX. Fedex uses contractors who are less than adequate for rural deliveries, rural deliveries are necessary for off grid development. If you plan on providing for this market, then maybe you should change your delivery service. If you can’t use other than FEDEX than forget my business. I can be quixotic.
I’ve been doing solar and LiFePO4 battery installations for a while now and this is one of the best chargers I’ve ever had the pleasure of using. Fantastic.
Great little Lithium charger.
I wished the connections was different but ok
