A power system for an electric vehicle comprising a battery pack connector unit and a battery assembly. The battery pack connector unit is electrically connected to a motor driver controller, and comprises at least a first battery connector and a second battery connector. The battery assembly includes at least a first battery pack and a second battery pack controlled by a first battery management system and a second battery management system respectively. When the first battery pack is electrically connected to the first battery connector, the first battery management system is arranged to become a master battery management system which is adapted to control the second battery management system as a slave battery management system, in such a manner that a respective voltage output of the battery assembly is optimally modulated by the master battery management system so as to create a single voltage output of the power system.
