terminal of Battery 3 is connected to the Positive terminal of Battery 2. The Negative ter-
minal of Battery 2 is connected to the Positive terminal of Battery 1. The Negative
terminal of Battery 1 becomes the Negative terminal of the 24V battery bank.
Parallel Connection
Fig 6.3: Parallel Connection
When two or more batteries are connected in parallel, their voltage remains the same
but their Ah capacities add up. Fig. 6.3 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 com-
mon Positive connection becomes 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. 6.4: Series-Parallel Connection
Figure 6.4 above shows a series – parallel connection consisting of four 6V, 200 AH bat-
teries 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.
