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 12V, 200 Ah batteries connected
in series to form a battery bank of 48V with a capacity of 200 Ah. The Positive terminal
of Battery 4 becomes the Positive terminal of the 48V 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 48V 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 48V, 100 Ah Battery Banks connected
in parallel to form a battery bank of 48V with a capacity of 400 Ah. The four Positive
terminals of Batery Banks 1 to 4 are paralleled (connected together) and this common
