Abstract
A battery-powered liquid pump sprayer having a control system capable of providing the user with a selectable series of defined spray application pressures, flow rates, and patterns that are accurately sustained over the duration of a spray application session. The pump sprayer has a control system for use with a battery having a voltage supply amount and a motor having a voltage demand amount that is less than the voltage supply amount. A microcontroller of the control system is coupled to the battery and the motor, and is programmed to provide a supply voltage from the battery to the motor and to ensure that the supply voltage is at least as much as the voltage demand amount
