Fig 7.3: Parallel Connection
When two or more batteries are connected in parallel, their voltage remains the same
but their Ah capacities add up. fig. 7.3 shows 4 pieces of 12V, 100 Ah batteries connect-
ed 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 Posi-
tive connection becomes the Positive terminal of the 12V bank. Similarly, the four Nega-
tive terminals of Batteries 1 to 4 are paralleled (connected together) and this common
Negative connection becomes the Negative terminal of the 12V battery bank.

Fig. 7.4: Series-Parallel Connection
figure 7.4 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.
