DOUBLE VOLTAGE. AMPS REMAIN THE SAME.
Three things to keep in mind:
- When connecting batteries in series, you increase the voltage and the amp-hour capacity remains the same. (see configuration 1)
- When connecting in parallel, the amp-hour capacity increases and the voltage remains the same. (see configuration 7)
- To increase both numbers, connect multiple sets in series/parallel. (see configuration 3)
Amps remain the same
Connection of two matched batteries used to double the voltage at the same amp-hour capacity, e.g. two 6-volt batteries to give 12 volts or two 12-volt batteries to give 24 volts.
