I bought this charger along with the lithium iron phosphate battery for the Bat Caddy. It is very easy to use with red (positive) and black (negative) wires. I charged my lithium iron phosphate battery immediately and the charger worked perfectly. I like the feature that shows when the battery is fully charged. The charger can also be used with lead-acid and lithium batteries and is intended to recycle lead-acid batteries. I haven't tried this yet. The price is right, about $25, and for now, 2 months, I'm very satisfied. It's small, has a fan and isn't too loud. Hey, for $25, that's a steal.
