ConneCTIon
Batteries are normally available in voltages of 2v, 6v and 12v and
with different Ah capacities. A number of individual batteries can be
connected in series and in parallel to form a bank of batteries with the
desired increased voltage and capacity.

Fig 5.5 Series connection
When two or more batteries are connected in series, their voltages
add up but their Ah capacity remains the same. Fig. 5.5 Above 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.

Fig 5.6 Parallel connection
When two or more batteries are connected in parallel, their voltage
remains the same but their Ah capacities add up. Fig. 5.6 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 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.
