A battery management system (BMS) controls lithium battery access on a utility vehicle. The BMS includes a battery interface that couples with a lithium battery, a load interface that couples with a set of loads of the utility vehicle, and control circuitry coupled with the battery interface and the load interface. The control circuitry mechanically disconnects the battery interface from the load interface in response to a sleep event. Additionally, after the battery interface is mechanically disconnected from the load interface, the control circuitry mechanically reconnects the battery interface to the load interface in response to a wakeup event. Furthermore, after the battery interface is mechanically reconnected to the load interface, the control circuitry maintains connection between the battery interface and the load interface to convey power from the lithium battery to the set of loads of the utility vehicle through the battery interface and the load interface.
