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
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 com
-
mon 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.

Fig. 4.4 Series-Parallel Connection
figure 4.4 above 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 con-
nected 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.

caution!
When 2 or more batteries / battery strings are connected in parallel and are
then connected to an Inverter Charger (See Figs. 4.3 and 4.4 given above),
attention should be paid to the manner in which the Inverter Charger is con-
