  "abstract": "A rail-mounted lift system includes a conductive rail electrically coupled to a power source; and a lift unit supported by the conductive rail, the lift unit comprising a battery and a switch for selectively coupling the battery to the power source via the conductive rail, the lift unit being configured to: determine a state of charge of the battery, determine a selected charge profile, and actuate the switch to supply power from the power source based on the state of charge and the selected charge profile.",
