Unlike wiring batteries in series when batteries are wired in parallel the voltage does not increase the output voltage is the average voltage of all batteries in the circuit. Many commercial batteries which offer higher voltages are made by connecting lower voltage cells in series.
9v Rechargeable 230 Series 100 Peakpower Nimh Batteries Pack Of 2
2 9v batteries in series. In theory a 6 volt 5 ah battery and a 12 volt 5 ah battery connected in series will give a supply of 18 volts 6 volts 12 volts and 5 ah. For example if a 3v and a 9v battery were wired in parallel the output voltage would be 6v 93 divided by 2 however the current will be total amperage of all. Connecting batteries of different voltages in series. The 2nd config is 4 parallel connections at each battery end also 2 rows of 4 batteries each row connected in series and of course the 3rd image is 3 parallel connections with 3 batteries connected across their and terminals and a single row of serial connected batteries to make 48v. A 6 volt battery is often three 2 volt cells and a 12 volt battery is usually six 2 volt cells. In this video i show you how to connect the 9 volt batteries in series without using wires.
Two batteries connected in series will have the same capacity but the voltage will be increased to the sum of the voltages provided by each battery. Shocking things with 300 9 volt batteries. Wiring batteries in series parallel increase your capacity wire 2 6v batteries to 1 12v duration. For example a 6 volt battery could be produced by connecting four 15 volt cells.
