Capacity 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)
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.
