1. A battery monitoring and characterization system, the system comprising:
a sheath that includes a first electrode and a second electrode, wherein the sheath is mounted on and affixed to one or more surfaces of a battery;
a drive-sense circuit (DSC) operably coupled to the first electrode via a single line, wherein, when enabled, the DSC operably configured to:
drive a signal to the first electrode via the single line and simultaneously sense the signal via the single line, wherein a change of a distance between the first electrode and the second electrode changes a capacitance between the first electrode of and the second electrode; and
generate a digital signal representative of a change of the capacitance between the first electrode and the second electrode;
memory that stores operational instructions; and
one or more processing modules operably coupled to the DSC and the memory, wherein, when enabled, the one or more processing modules configured to execute the operational instructions to process the digital signal to determine the change of the capacitance between the first electrode and the second electrode.
