Specification

For 36 volt lithium batteries
We highly recommend 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
43V 20A
Dimensions
13.86" x 5.71" x 2.83" (352mm x 145mm x 72mm)
Terminal Connections
Anderson 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 20A. For example, a 36v 110Ah battery will 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).
Waterproof Rating
IP67
What voltage should LiFePO4 batteries be charged at?
43V recommended for 36V DL Batteries, this charger is at 43V.
Recommendation
The 36V 20a charger is great for 36V 60Ah and 36V 110Ah
