Claim 7:
8. The electric power tool as in claim 1, wherein:
the first signal is a first digital signal having a first voltage level and a second voltage level different than the first voltage level of the first digital signal, and the second signal is a second digital signal having a first voltage level and a second voltage level different than the first voltage level of the second digital signal,
the first battery pack is configured to output current at a first power supply voltage that is equal to or higher than the first and second voltage levels of the first digital signal,
the second battery pack is configured to output current at a second power supply voltage that is equal to or higher than the first and second voltage levels of the second digital signal, and
the electric power tool further comprises:
at least one cut-off switch controllable by the controller and disposed between the controller and the microprocessor of the first battery pack, the cut-off switch being configured to cut off or open an electrical connection between the controller and the microprocessor of the first battery pack, and
at least one bypass circuit comprising a diode electrically connected between a positive electrode and a negative electrode of one of the first or second battery packs, the at least one bypass circuit also comprising a fuse.
