Product Description
This Dakota Lithium 36V 20A lithium marine battery charger was built to charge large lithium batteries quickly. Dakota Lithium has optimized this charger for use with our lithium iron phosphate batteries. Built in a waterproof aluminum case, this charger is rated at 20 amps and will charge a Dakota Lithium 36V 60Ah battery in 3 hours or a 110Ah battery in 5.5 hours. All 36 volt Dakota Lithium batteries should be charged using a 36V LiFePO4 battery charger.
Includes Anderson plug with ring terminals for safe & easy charging. Simply plug the charger into the Anderson plug, and remove when done.
Charger Rating
Input:100-120VAC, 50/60HZ
Output: 43.8 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, 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 battery 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, this 36V 20A lithium battery charger will charge a 36V 60 amp hour battery (Ah) in 3 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 23Ah 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). This onboard battery charger is ideal for 60Ah and larger 36V lithium (LiFePO4) batteries.
What Voltage Should LiFePO4 Batteries Be Charged At?
43.8 volts is recommended for Dakota Lithium 36V batteries. This 36V Lithium battery charger charges at 43.8 volts.
Onboard Mounting
Mounting flange is built-in to the aluminum case for easy installation.
Waterproof Rating
IP67
Heat Warning: The waterproof design requires the charger to be fanless and all heat is dissipated through the aluminum case. The case will become very hot when charging.
