Question:What is the difference in connection batteries in parallel or series?
Answer: When you connect batteries in
parallel you connect positive to positive and negative to
negative. With a parallel connection you are increasing the
size of the pool of power you have but the voltage stays the
same as the original batteries. To connect in series you
connect positive to negative then you get one positive from one
battery and the negative from the other battery. When you
connect two batteries in series it adds the voltage up. So if
you have two 12 volt batteries and connect them in series you
will end up with 24 volts.
