3.4.2 Parallel Connection
Fig 3.6 Parallel Connection
When two or more batteries are connected in parallel, their voltage remains the same but their
Ah capacities add up. fig. 3.6 above shows 4 pieces of 12V, 100 Ah batteries connected in
parallel to form a battery bank of 12V with a capacity of 400 Ah. The four Positive terminals of
batteries 1 to 4 are paralleled (connected together) and this common Positive connection be-
comes the Positive terminal of the 12V bank. Similarly, the four Negative terminals of batteries
1 to 4 are paralleled (connected together) and this common Negative connection becomes the
Negative terminal of the 12V battery bank.

Series – Parallel Connection
Fig. 3.7 Series-Parallel Connection
figure 3.7 shows a series – parallel connection consisting of four 6V, 200 Ah batteries to form a
12V, 400 Ah battery bank. Two 6V, 200 Ah batteries, batteries 1 and 2 are connected in series
to form a 12V, 200 Ah battery (String 1). Similarly, two 6V, 200 Ah batteries, batteries 3 and 4
are connected in series to form a 12V, 200 Ah battery (String 2). These two 12V, 200 Ah Strings
1 and 2 are connected in parallel to form a 12V, 400 Ah bank.
