... and rated to 2.7 Volts). To be able to use the supercapacitors in the circuit with a nominal voltage over 12 Volts, they must be connected in series (end to end). This is similar to connecting batteries end to end to achieve the desired voltage. For instance, a car battery is typically composed of 6 battery...
