1. A utility vehicle, comprising:
a lithium battery constructed and arranged to store electric power;
an electric motor coupled with one or more ground engaging members;
a motor controller coupled with the lithium battery and the electric motor, the motor controller being constructed and arranged to operate in (i) a normal mode in which the motor controller provides electric power from the lithium battery to the electric motor to turn the one or more ground engaging members, and (ii) a walkaway mode in which the motor controller configures the electric motor to provide braking torque; and
an acceleration pedal coupled with the motor controller, the accelerator pedal being constructed and arranged to provide an accelerator signal to the motor controller, the accelerator signal indicating a current amount of pedal depression encountered by the accelerator pedal;
wherein the motor controller is further constructed and arranged to enter the walkaway mode when the accelerator signal indicates that the accelerator pedal is not depressed; and
wherein the motor controller is further constructed and arranged to enter the walkaway mode when a keyed switch of the utility vehicle is set to an OFF position, the keyed switch being electronically coupled with a battery management system (BMS) of the lithium battery.
