How do you wire 10 12 volt batteries to 120 volts?

To wire 10 12-volt batteries to achieve 120 volts, you need to connect them in a series configuration. Specifically, connect 10 batteries in series to produce a total of 120 volts (12 volts x 10 = 120 volts). Ensure that the positive terminal of one battery connects to the negative terminal of the next battery in the series. Finally, the output can be taken from the first battery's positive terminal and the last battery's negative terminal.
