The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity. This means if one 5 volt battery powers a circuit for two hours two 5 volt batteries in parallel would last four hours but supply only 5 volts total.

Circuit with two batteries in series. Note we say minimize because even batteries coming off the same production line can vary slightly in these measurements. When connecting batteries in series the general advice is to use batteries of the same ratings and the same make and model in order to minimize differences in exact voltage and amperage. Wiring two batteries in series. For example for the above circuit the measured voltage across battery 1 is 48v and battery 2 is 36v. Than 36v 23v gives 13v. How to wire batteries in series or in parallel step 1.
Batteries in seriesin this type of combination end of the battery is connected to the end of the other battery. Pictures given below show the examples of this type of combination. 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. If you connect batteries so that the positive of one connects to the negative of the other you will find that their respective voltages add. By contrast the voltage for batteries in parallel do not add up though their capacities do. For instance three 5 volt batteries in series produce a total of 15 volts.
Use another set of cables to connect the open positive and negative terminals to your application. Batteries can be combined in three ways in series in parallels and in opposite directions. An example of simplifying a seemingly complicated resistor circuit if youre seeing this message it means were having trouble loading external resources on our website. Negating 48v 36v12v gives us battery 1 voltage. Similarly if battery 3 is at 23v. Okay youre going to need some batteries to wire together and some way to wire them together.
Other batteries voltages can be calculated with same method. Total emf of the circuit is. Connecting components in series means to connect them in line with each other so that there is but a single path for electrons to flow through them all. Wiring multiple power sources in series will increase the available voltage. To connect batteries in a series use jumper wire to connect the negative terminal of the first battery to the positive terminal of the second battery. So battery 2 is supplying 13 volts in series string array.
