The Dakota Lithium 12V 20A Ultra-Fast Lithium LIFEPO4 Battery Charger is a true powerhouse in design, fully optimized to charge large 12V lithium batteries to the fullest efficiency while ensuring a long battery lifespan. The charger itself is built with a robust high tensile aluminum casing for greater durability and more rapid cooling. The included Anderson plug outfitting this charger comes with a ring terminal adapter, allowing users greater versatility in their charging methods. Batteries larger then 25Ah in capacity are recommended to be used with this charger, while batteries smaller then 25Ah should be charged with the 3A charger.

FOR 12 VOLT LITHIUM BATTERIES

It is highly recommended that 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, 20.0 amps

TERMINAL CONNECTIONS

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.

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 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.

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 laboratory testing it was found that the longest lifespan for Dakota Lithium batteries was at a charging speed of 0.3C or less (Dakota Lithium recommends 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.
