It shows eight batteries wired into two series strings of four batteries each. If they are 6V batteries of 250AH each, then each string has a voltage of 24V (6V x 4) and 250AH. The two series strings are then wired in parallel, which doubles the amperage capacity to 500AH, without changing the voltage. Here, two 12V batteries are paralleled for the same voltage but double the amperage.
