Series Connection of Batteries
When two or more batteries are connected in series, their voltages add up but their Ah capacity remains the
same. Fig. 9.1 above shows 2 pieces of 6V, 200 Ah batteries connected in series to form a battery bank of 12V
with a capacity of 200 Ah. The Positive terminal of Battery 1 becomes the Positive terminal of the 12V bank.
The Negative terminal of Battery 1 is connected to the Positive terminal of Battery 2. The Negative terminal of
Battery 2 becomes the Negative terminal of the 12V battery bank.

When two or more batteries are connected in parallel, their voltage remains the same but their Ah capacities
add up. Fig. 9.2 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 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.
