Series Amp Parallel Battery Connections With A Shunt
How to hook two batteries together for 12 volts. There will be 24 volts about 28 volts with an alternator if two 12 volt batteries are wired together in series. One way doubles the volts of the two batteries and the other keeps the same amount of volts. Each 6 volt battery pair operates as a single 12 volt battery. The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity. Connect one of the battery cables to the positive terminal on battery number one. Connect the positive terminal of one battery to the negative terminal of the other.
Attach the positive and negative terminals from each battery together. Ground the negative terminal of battery 2. You can then connect each 6 volt pair in parallel with another pair to create a larger 12 24 or 48 volt battery bank. There are two ways to wire up two batteries. Connect the negative terminal of battery 1 to the positive terminal of battery 2. In parallel the voltage stays the same and in series it is doubled.
Make a series connection to the two 12 volt batteries. I have produced a diagram showing the connections for you. This is called a series parallel configuration. To wire two 6 volt batteries in series to produce 12 volts you would connect the load to the positive terminal of battery 1. Following this example where there are two 12v 200ah batteries connected in series we will have a total voltage of 24v volts and an unchanged capacity of 200ah ampere hour. To produce a 12 volt output two 6 volt deep cycle batteries must be wired in series positive to negative.
