1. A lift device, comprising:
a linear actuator configured to selectively move a work platform between a raised position and a lowered position, the linear actuator including an electric motor;
a drive motor configured to rotate a first wheel to propel the lift device;
a rechargeable battery system including a battery, a heating system, and a battery charger, wherein the battery is configured to power the electric motor of the linear actuator, and wherein the battery charger is configured to simultaneously charge the battery and provide power to the heating system to heat the battery; and
a control system configured to manage a battery usage of the battery during operation, the control system comprising:
a vehicle controller in communication with the drive motor and the battery; and
a lift controller in communication with the vehicle controller and the linear actuator, wherein at least one of the vehicle controller and the lift controller is configured to receive current delivery limits and regeneration limits of the battery and to limit operational speeds of at least one of the drive motor and the linear actuator based on the current delivery limits and the regeneration limits.
