A battery sensor system (BSS) includes a battery operably coupled to a plurality of loads via a wired connection, where a first load is operably coupled to a terminal of the battery via a first portion of the wired connection and a second load is operably coupled to the terminal via a second portion of the wired connection. The BSS further includes a first drive sense circuit operably coupled proximate to the battery to sense a first voltage. The BSS further includes a second drive sense circuit operably coupled proximate to the first load to sense a second voltage, where the second voltage and first voltage are different based on an impedance of the wired connection between the first point and the second point. The BSS further includes memory and processing modules to process the first and second voltages to determine operational status of the battery, wired connection, and loads.
