Quadruple Voltage.

Capacity Remain The Same.

Three things to keep in mind:

1. When connecting batteries in series, you increase the voltage and the amp-hour capacity remains the same. (see configuration 1)
2. When connecting in parallel, the amp-hour capacity increases and the voltage remains the same. (see configuration 7)
3. To increase both numbers, connect multiple sets in series/parallel. (see configuration 3)

Configuration 6:

Quadruple Voltage
Triple Capacity

Series/Parallel:

Connection of twelve matched batteries to quadruple the voltage at triple the capacity. Sometimes used in very large golf utility cars, sweepers/scrubbers, and EV and marine deep cycle application or in large, long-haul trucks, RV’s, and buses for engine cranking applications where even more deep cycle capacity is needed beyond Figure 5 Configurations.
