Fig 7.2: Series Connection
When two or more batteries are connected in series, their voltages add up but their Ah
capacity remains the same. Fig. 7.2 shows 4 pieces of 6V, 200 Ah batteries connected in
series to form a battery bank of 24V with a capacity of 200 Ah. The Positive terminal
of Battery 4 becomes the Positive terminal of the 24V bank. The Negative terminal of
Battery 4 is connected to the Positive terminal of Battery 3. The Negative terminal of
Battery 3 is connected to the Positive terminal of Battery 2. The Negative terminal 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.

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.
