To obtain 24 volts DC, how should two 12-volt batteries be connected?

Explanation:
To get 24 volts from two 12-volt batteries, connect them in series. In a series setup you link the positive terminal of one battery to the negative terminal of the other, and use the remaining free terminals as the 24V output. When connected this way, the voltages add together (12V + 12V = 24V) while the current capacity stays the same as a single battery. If you wired them in parallel, you’d still have 12V but with increased capacity. A single 24V battery would supply 24V on its own, and three 12V batteries in series would give 36V.
