How Can Batteries Be Connected?


Note: When interconnecting batteries (cells) they must be the same type batteries (cells).  
Batteries may be connected in series. The positive terminal of the first battery is connected to the negative terminal of the second battery, the positive terminal of the second is connected to the negative of the third, etc. The voltage of the assembled battery is the sum of the battery voltages of the individual cells. The capacity of the battery is unchanged. 
Batteries may be connected in parallel. The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third, etc. The negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third, etc. In this configuration, the capacity increases. The sum of each cell's capacity is added to each other. The battery pack voltage is unchanged. 
Example, if you take 5- 6 volt / 10ah batteries and connect the batteries in series. You would end up with a battery pack that is 30 Volts and 10AH. If you connect the batteries in parallel, you would end up with a battery pack that is 6 Volts and 50AH. This is how an ordinary auto battery is made. 6- 2 volt cells are put in series to make a 12V battery. The 6 cells are just enclosed in one case. Most battery packs are done the same way.  Thanks AGT Battery Supply
