Dakota Lithium has optimized this charger for use with our lithium iron phosphate batteries (LiFePO4). Rated at 10 amps this is the perfect size for Dakota 54 Ah or 100 Ah batteries. 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.
