Battery Series Connection
When batteries are connected with the positive terminal of one battery to the negative
terminal of the next battery, they are connected in series. In a series configuration, the
battery bank has the same Ah rating of a single battery, but an overall voltage equal to
the sum of the individual batteries. See below.
Battery Series-Parallel Connections
As the name series-parallel implies, both the series and parallel configurations are used
in combination. The result is an increase in both the voltage and the capacity of the total
battery bank. The smaller, lower voltage batteries are first connected in series to obtain
the necessary voltage, and then these “batteries connected-in-series” sets are
connected in parallel to increase the battery bank capacity. See below.
