Non-sequential monitoring of battery cells in battery monitoring systems, and related components, systems, and methods are disclosed. In one embodiment, a battery monitoring system control unit is provided. The battery monitoring system control unit is configured to control battery monitoring devices. Each battery monitoring device is configured to be coupled to a subset of battery cells electrically connected in series in a sequential order to form a battery. The battery monitoring system control unit is further configured to instruct the battery monitoring devices to test an ohmic value of each battery cell of the battery cells of the battery in a non-sequential order. In this manner, heat generated in the battery monitoring devices from the testing may be more effectively dissipated, which can also allow for the battery monitoring devices to be employed in higher operating temperature environments.
