What is the difference between battery series and parallel

The reason why batteries need to be connected in series and parallel is to obtain high voltage or high current. Connect multiple batteries in series to get the desired operating voltage. If you want higher capacity and higher current, you should connect the batteries in parallel. There are also some battery packs that combine the two methods of series and parallel. Portable devices that require high power in series are generally powered by a battery pack with two or more batteries connected in series. If a high-voltage battery is used, the size of the conductor and switch can be made small. For example, industrial power tools generally use 12V~19.2V for power supply, but advanced tools use 24V~36V. Under the limitation of size, the battery has to be connected in series to increase the voltage. In order to get more power, you can connect two or more batteries in parallel. In addition to connecting the batteries in parallel, another solution is to use larger batteries. Due to the limitations of the available batteries, this method is not suitable for all situations. In addition, large-size batteries are not suitable for the external specifications required for special batteries. Most chemical batteries can be used in parallel, and lithium-ion batteries are most suitable for parallel use. In a battery pack formed by connecting four batteries in parallel, the voltage remains at 1.2V, while the current and running time are increased to four times.
