A battery pack monitoring system for monitoring a plurality of battery modules within a battery pack. Primary monitoring circuits are coupled to monitor respective battery modules and have circuitry to output measurement values that correspond to the respective battery modules. At least one standby monitoring circuit is coupled to monitor at least one of the battery modules and includes circuitry to output a first measurement value that corresponds to the battery module. A pack controller selectively applies, in a determination of battery pack status, either the first measurement value from the standby monitoring circuit or a second measurement value from one of the primary monitoring circuits.
