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.
