1. A battery system comprising:
an output configured to provide output power to a load;
one or more battery cells configured to store electrical energy to provide to the load; and
a battery management system configured to
receive one or more operational parameters of the battery system,
determine whether the one or more operational parameters are less than at least one operational-parameter threshold,
modify at least one discharge threshold of the one or more battery cells responsive to determining that the one or more operational parameters are less than the at least one operational-parameter threshold,
control the battery system to be in a first battery-optimization mode responsive to determining that the discharge level of the one or more battery cells is below a first discharge threshold,
control the battery system to be in a second battery-optimization mode responsive to determining that the discharge level of the one or more battery cells is below a second discharge threshold, the second discharge threshold being less than the first discharge threshold, and
control the battery system to be in an active mode responsive to determining that the discharge level of the one or more battery cells is above the first discharge threshold, wherein the first battery-optimization mode includes disabling functionality of the battery management system to reduce power consumption relative to the active mode.
