Built to trickle charge large 24V (volt) batteries, this Lithium / LFP / LiFePO4 / Li-ion charger will charge any lithium battery at a rate of 5A (amps) per hour. 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. This charger is rated at 5A and will charge a 24V 10Ah Dakota Lithium battery in <2 hours, or a 24V Dakota Lithium 50Ah battery in <10 hours. This charger will work with any Dakota Lithium battery wired in series to make a  24V LiFePO4 lithium battery. All 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.
