GENERAL INFORMATION: BATTERIEs
Positive terminal of Battery 4 becomes the Positive terminal of the 24 V 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 24 V battery
bank.

When two or more batteries are connected in parallel, their voltage remains the
same but their AH capacities add up. Fig. 3.3 above shows 4 pieces of 12 V, 100 AH
batteries connected in parallel to form a battery bank of 12 V 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 12 V 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 12 V battery bank.
