We wish to measure the voltage across four 12 V batteries wired in series to make a 48 V battery in a solar photovoltaic system as it charges and discharges with time. The voltage produced by a battery does not stay constant but will increase as it charges and decrease as it discharges. If we have a data logger that can only measure voltages between 0V and 10V, design a circuit that allows us to monitor the battery voltage as it changes between 45V and 55V.
