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 ter-
minal 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 above 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 com-
mon 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.
