    Abstract: Systems and methods for under-voltage protection features in power tools. One power tool provides a motor, a power source, a voltage sensor, and a controller. The power source is configured to selectively provide power to the motor. The voltage sensor is configured to sense a voltage of the power source. The controller is configured to monitor, with the voltage sensor, the voltage of the power source and reduce, when the voltage of the power source is less than or equal to a first threshold value, a current provided from the power source to the motor. The controller is configured to stop, when the voltage of the power source is less than or equal to a second threshold value, providing the current from the power source to the motor.

    Abstract: The present disclosure is a hydraulic jack including a housing that supports a reservoir, a motor, a pump assembly, and a lift assembly. The housing includes a lift portion in which the lift assembly is at least partially supported, and a power supply portion configured to removably receive a power supply. The motor is configured to receive power from the power supply. The pump assembly receives a rotational output from the motor to generate a flow of hydraulic fluid from the reservoir. The lift assembly is extendable between a retracted position and an extended position in response to the flow of hydraulic fluid and is configured as a three-stage lift assembly with a first stage that extendable in a first manner, and second and third stages extendable in a second manner.
