A construction machine is disclosed having a body, one or more movement elements, and a control panel comprising a propulsion controller operable between a lower propulsion controller limit and an upper propulsion controller limit. The construction machine further comprises: a propulsion electric motor adapted to drive the one or more movement elements, one or more batteries adapted to power the propulsion electric motor, a control circuit adapted to receive a propulsion controller input indicative of a state of the propulsion controller between the lower propulsion controller limit and the upper propulsion controller limit, and to operate the propulsion electric motor in accordance with a propulsion variable based on the propulsion controller input. While operating the propulsion electric motor in accordance with the propulsion variable, the control circuit is further adapted to: receive a propulsion current signal indicative of an amount of current drawn by the propulsion electric motor, and in accordance with the propulsion current signal satisfying propulsion reduction criteria, reduce the propulsion variable by a propulsion reduction amount such that the propulsion variable is below a maximum propulsion variable.
