3.4.2 Parallel connection

12V Inverter
or 12V Charger
When two or more batteries are connected in parallel, their voltage remains the same but their
Ah capacities add up. fig. 3.6 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 be-
comes 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.
3.4.3 Series – Parallel connection
12V Inverter
or 12V Charger
figure 3.7 shows a series – parallel connection consisting of four 6V, 200 Ah batteries to form a
12V, 400 Ah battery bank. Two 6V, 200 Ah batteries, batteries 1 and 2 are connected in series
to form a 12V, 200 Ah battery (String 1). Similarly, two 6V, 200 Ah batteries, batteries 3 and 4
are connected in series to form a 12V, 200 Ah battery (String 2). These two 12V, 200 Ah Strings
1 and 2 are connected in parallel to form a 12V, 400 Ah bank.
