Double Voltage.

Increase Capacity By 3X’s.

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 3:

Double Voltage
Increase Capacity by 3X’s

Series/Parallel:

Connection of six matched batteries used to double the voltage at triple the capacity. Often used in trucks, buses, marine, RV, and solar/wind energy back-up applications where additional capacity is needed beyond Figure 2 Configurations.
