The cells are connected in series and in parallel, into battery packs, to achieve the desired voltage and energy capacity. An electric car for example requires 400-800 volts and one single battery cell typically features 3-4 volts. Finally, the battery pack is the complete enclosure that delivers power to the electric vehicle.
The main function of parallel connection is to increase the capacity while maintaining the same voltage. For example, if you connect eight 3.2V, 3000mAh LiFePO4 26650 cells in parallel, the result will be a 3.2V 24Ah battery pack. Advantages of parallel connection: Increases the overall capacity, allowing the battery pack to store more energy.
