Dakota Lithium has optimized this charger for use with our lithium iron phosphate batteries (LiFePO4). 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. This charger charges at a speed of 3 amps an hour and is optimal for batteries < 25Ah. For batteries greater than 25Ah like the 54Ah or 100Ah battery we recommend the 10 amp charger.
Compatible with lithium-ion (li-ion), lithium iron phosphate (LiFePO4 or LFP), lithium-manganese-cobalt-oxide (NMC), or lithium titinate oxide (LTO) batteries.

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
