i have a drycell with just a + and a - so i have like 13.5 v going through it at all times. if i make another cell is there a way to hook them up to cut the voltage in half? would i just hook the + of the first one the the - of the second one? or both the + together and so on. Or..... last minuet question here, would it be better to make 3 and wire them all up and get about 4.5v per cell? thanks for the help
