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, 40.0 amps, 10 amps per bank / channel

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.

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 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.

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.
