1. A smart label comprising:
a battery comprising multiple battery cells interconnected in series;
a first wireless radio directly connected to and powered by only one of the multiple battery cells; and
a second wireless radio directly connected and powered by all of the multiple battery cells operating at a higher voltage and having a higher power requirement than the first wireless radio,
wherein the battery is configured to selectively and directly power one or both the first wireless radio and the second wireless radio based on operating parameters comprising at least one of an open-circuit voltage (OCV) of the battery, a temperature of the battery, a Coulomb counter output, a state-of-health (SOH) of the battery, and an internal resistance of the battery.
