Built to charge large batteries quickly, this lithium / LFP / LiFePO4 charger will charge any lithium battery at a rate of 20 amps. Dakota Lithium has optimized this charger for use with our lithium iron phosphate batteries (LiFePO4 or LFP). 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 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 LiFePO4 compatible charger like this one. SLA chargers will reduce the performance and lifespan of the battery.
Included 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).
A 10 amp charger is included with every Dakota Lithium 54Ah and 100Ah battery purchase. This charger is an add-on and charges twice as fast. Great for RVs, Boats, Solar, or other applications where you need to charge your batteries as fast as possible.

FOR LITHIUM AND LIFEPO4 BATTERIES We highly recommend you use a LiFePO4 compatible charger. Chargers for lead acid batteries may work, but will decrease performance and lifespan of the battery.
TERMINAL CONNECTIONS Alligator clips / Anderson SB 50 connections depending on charger 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? This depends on the amp rating of the charger. To determine your charging speed take the amp hour rating of your battery and divide by the charger amp rating.
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 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).
WHAT VOLTAGE SHOULD LIFEPO4 BATTERIES BE CHARGED AT? 14.4 Volts is recommended for 12V Dakota Lithium (LifePO4) batteries
CHARGER USAGE - Please follow the usage guideline associated with each different size of charger.
