Voltage translator circuitry may include a path including a first resistor, a current controlling device, and a second resistor coupled in series. The voltage translator circuitry may further include an operational amplifier having a positive supply terminal to accept a positive supply voltage and a negative supply terminal to accept a negative supply voltage, neither the positive or negative supply voltage at ground voltage. The first resistor may further be coupled to a positive terminal of the battery cell to be monitored. The operational amplifier may have an input coupled to a negative terminal of the battery cell to be monitored. The voltage translator circuitry may further include an output terminal coupled to a node of the path between the current controlling device and the second resistor. The output terminal may be configured to provide the ground referenced cell voltage for the battery cell.
