Product Description
This Dakota Lithium 12V 20A lithium 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 high tensile aluminum case for rapid cooling, this charger is rated at 20 amps and will charge a Dakota Lithium 54 Ah battery in 2.5 hours or a 100 Ah battery in <5 hours. For smaller batteries (<25 Ah) we recommend the 3 amp charger. All 12 volt Dakota Lithium batteries should be charged using a 12V LiFePO4 battery charger like this one.
Includes Anderson plug with ring terminals for safe & easy charging. Simply plug the charger into the Anderson plug, and remove when done. Also compatible with all Connect-Ease trolling motor wiring kits (add on).
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, 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 12V 20A lithium battery charger will charge a 54 amp hour battery (Ah) 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 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).
What Voltage Should LiFePO4 Batteries Be Charged At?
14.4 volts is recommended for Dakota Lithium batteries. This 12V Lithium battery charger charges at 14.4 volts.
Upgrade For Dakota 54Ah - 200Ah Batteries
A 10 amp charger is included with every Dakota Lithium 54Ah - 200Ah battery purchase. This 20A battery charger is an upgrade that will charge twice as fast. Great for RVs, Boats, Solar, or other applications where you need to charge your batteries as fast as possible.
