Battery Series Connection

Battery Series-Parallel Connections 

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.

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. This is
common with all battery-inverter system voltages. 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.
