SERIES BATTERY DISCHARGE MANAGEMENT ACROSS A DEVICE SECTION BOUNDARY

An electronic device supplies power to system load(s) from a first battery power source and a second battery power source connected in series across a re-configurable device section boundary. A battery monitor monitors voltage across each individual battery cell within the first and second battery power sources. The battery monitor directs a charge circuit as to how and when to charge the first and second battery power sources using an external power source. The battery monitor also directs the charge circuit as to how and when to use the first and second battery power sources to power the system load(s).
