It detects the battery load and supplies up to 50V, and shuts off once the amperage gets to a low threshold, and no further charge is accepted by the battery. This is not approved for lithium ion batteries however I used it daily for a 48v lithium ion battery with no issues. One down side is the charger will not initiate a charge on your batterie(s) if they are completely dead and less than roughly 28V.
