PARALLEL & SERIES CONNECTIONS
Applications often demand more voltage or more ampere capacity than the
capacity of one battery. By connecting multiple batteries of the same make/
model/capacity in series, parallel or series parallel configurations, output voltage
or battery bank amperage may be increased as needed.
To increase voltage, batteries are connected in series. Capacity of the battery
bank remains the same as voltage increases. To increase the available amount
of current and capacity, batteries are connected in parallel. In this situation it
is best to use lower voltage, higher capacity cells to minimize the amount of
parallel strings.
To increase voltage, connect the batteries in series as shown in Figure 1.
