3.4 INSTALLING BATTERIES - SERIES AND PARALLEL 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 3.5 Series Connection
When two or more battery packs / battery banks are connected in series, their voltages add up but their Ah capacity
remains the same. Fig. 3.5 shows 4 pieces of 12V, 200 Ah battery packs connected in series to form a battery bank
of 48V with a capacity of 200 Ah. The Positive terminal of Battery Pack 4 becomes the Positive terminal of the 48V
bank. The Negative terminal of Battery Pack 4 is connected to the Positive terminal of Battery Pack 3. The Negative
terminal of Battery Pack 3 is connected to the Positive terminal of Battery Pack 2. The Negative terminal of Battery
Pack 2 is connected to the Positive terminal of Battery Pack 1. The Negative terminal of Battery Pack 1 becomes the
Negative terminal of the 48V battery bank.

Fig 3.6 Parallel Connection
When two or more battery packs / battery banks are connected in parallel, their voltage remains the same but their
Ah capacities add up. Fig. 3.6 shows 4 sets of 48V, 100 Ah battery banks connected in parallel to form a battery
bank of 48V with a capacity of 400 Ah. The four Positive terminals of battery banks 1 to 4 are paralleled (
connected
together
) and this common Positive connection becomes the Positive terminal of the 48V bank. Similarly, the four
Negative terminals of battery banks 1 to 4 are paralleled (
connected together
) and this common Negative connection
becomes the Negative terminal of the 48V battery bank.
