This 72V lithium charger is rated at 10 amps and will charge a 72V 55Ah battery in 5 hours or a 72V 110 Ah battery in 11 hours.
Description
Designed for use with the Dakota Lithium 72V 55Ah Lithium Battery or any 72V lithium battery with more than 10Ah of capacity. Optimized for use with lithium iron phosphate batteries (LiFePO4 or LFP) but is compatible with most lithium battery chemistries as long as the battery voltage is 72 volts. Not recommended for charging lead acid or SLA batteries, it is too powerful. Built in a high tensile aluminum case for rapid cooling, this charger is rated at 10A. Includes an Anderson plug with ring terminals for safe & easy charging. Simply plug the charger into the Anderson plug, and remove when done. All Dakota Lithium batteries should be charged using a LiFePO4 compatible charger like this one. SLA chargers will reduce the performance and lifespan of the battery.

For 72 volt lithium batteries:
We highly recommend you use a LiFePO4 compatible charger. 72v chargers for lead acid batteries may work, but will decrease performance and lifespan of the battery.
-
Charger rating:
INPUT 100-240 volts, 50/60HZ. OUTPUT: 86.4 volts, 10 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 10 amps. To determine your charging speed take the amp hour rating of your battery and divide by 10. For example, a 72v 55 amp hour battery (Ah) would charge in 5.5 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 8 amp charger with a 8 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?:
86.4 volts is recommended for 72v Dakota Lithium (LiFePO4) batteries. This charger charges at 86.4 volts.
