connecting Batteries
Series connection
Fig. 4.2 Series Connection
When two or more batteries are connected in series, their voltages add up but their Ah
capacity remains the same. fig. 4.2 above shows 4 pieces of 6V, 200 Ah batteries connect-
ed 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.
parallel connection
Fig. 4.3 Parallel Connection
When two or more batteries are connected in parallel, their voltage remains the same but
their Ah capacities add up. fig. 4.3 above shows 4 pieces of 12V, 100 AH batteries connect-
ed 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.
