The system further includes a rechargeable battery pack removably and independently coupled to the power tool and the non- motorized sensing tool. The battery pack is operable to power the motor to drive the drive mechanism and the output element when connected to the power tool, and is operable to power the circuit board and the sensing element when connected to the non-motorized sensing tool.
A power tool, such as a pipe cutter, includes a rotatable cutting head assembly, an electric motor connectable to a rechargeable battery, and a controller. The controller is configured to monitor the state of charge on the battery, compare the state of charge to one or more thresholds, and prevent or limit operation of the power tool when the state of charge is less than or equal to one or more of the thresholds. In some embodiments, the threshold includes the state of charge required to cut a pipe, the state of charge required to return the cutting head assembly to a home position, and a state of charge indicative of an overdischarged condition of the battery. In some embodiments, the controller is configured to detect when the pipe cutter has completed cutting the pipe and returns the cutting head assembly to the home position.
