A system (100) includes a battery pack (106) having a first battery module (108), a second battery module (108), and a busbar (202) that couples the first and second battery modules; a battery management controller (130) having a first wireless transceiver (134); and a battery monitor (132) coupled to the first battery module and to the busbar. The battery monitor includes monitoring circuitry (302) configured to receive a first indication of a parameter of the first battery module; a second wireless transceiver (136) configured to provide the first indication to the battery management controller via a wireless connection to the first wireless transceiver; and a busbar voltage circuit (304) configured to receive a second indication of a voltage across the busbar, and, responsive to the second indication being greater than a voltage threshold, provide a first signal to the second wireless transceiver to cause the second wireless transceiver to be in a higher-power state.
