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 6V, 200 Ah batteries
connected in series to form a battery bank of 24V with a capacity of 200 Ah. The
Positive terminal of Battery 4 becomes the Positive terminal of the 24V 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 24V battery
bank.
