Title: SERIES-CONNECTED BATTERY PACKS, SYSTEM AND METHOD
Abstract:
A power device, system and method. The device may include a housing defining a first support operable to support a first battery pack, and a second support operable to support a second battery pack; a circuit selectively electrically connecting the first battery pack and the second battery pack in series, the circuit including an output terminal to provide an output voltage to a powered device, a first bypass portion operable to selectively electrically disconnect the first battery pack from the circuit, and a second bypass portion operable to selectively electrically disconnect the second battery pack from the circuit; and a boost converter electrically connected to the circuit and operable to boost a voltage at the output terminal.
