Battery packs are comprised of cells that can be arranged in two different formats – series or parallel. Each cell in a battery pack may contain the same amount of energy and, if cells are added, the amount of available energy is increased proportionally. However, there is a significant difference in how that energy can be used in series vs ...
Due to the limited voltage and capacity of the single battery, in actual use, a series-parallel combination is required to obtain a higher voltage and ability to meet the existing power supply requirements of the equipment. Lithium batteries in series: the voltage is added, the capacity remains unchanged, and the internal resistance increases.
) First connect in series according to the capacity of the lithium battery cell, such as 1/3 of the capacity of the entire group, and finally connect in parallel, which reduces the probability of failure of the large-capacity lithium battery module; first connect in series and then it is of great help to the consistency of the lithium battery pack.
If we connect the positive (+) terminal of battery to negative (-) and negative to positive terminal as shown in the below fig, then the batteries configuration would be in series.
If the configuration consists of eight cells with the configuration of 4SP2, two cells are in parallel, and four packs of this parallel combination are connected in series. The total power produced by this pack is 97.92 Wh. The IEC 62133 harmonized the safety requirements for nickel and lithium-based batteries and cells for portable applications.
In a series configuration, a battery is as strong as the weak link in the battery chain, so the higher-capacity cell cannot charge more than the weaker cell. The weaker cell also discharges and charges first, which can cause problems like over-discharge and over-charge in the device.
This combination of cells is called a battery. Sometimes battery packs are used in both configurations together to get the desired voltage and high capacity. This configuration is found in the laptop battery, which has four Li-ion cells of 3.6 V connected in series to get 14.4 V.

These all are low-power devices, so they use a 1.5 V alkaline battery. Mobile phones and tablets are also available in a single-cell configuration of a 3.6 V Li-ion battery. The image below shows the single ...
In series connections, the total voltage adds up, while in parallel connections, the voltage remains the same but the capacity increases. Understanding these differences helps in designing and configuring battery systems for specific power requirements. Series Connections: Connecting batteries in series increases the overall voltage.
In a series connection, the current remains the same through each cell. For a 1A current flow, every battery in the series will deliver 1A. · Energy Distribution. Energy distribution is another factor to consider. Power in series circuits comes from the sum of the energy stored in each cell. A higher number of cells lead to more energy ...
Batteries achieve the desired operating voltage by connecting several cells in series; each cell adds its voltage potential to derive at the total terminal voltage. Parallel connection attains higher capacity by adding up the total ampere-hour (Ah). Some packs may consist of a combination of series and parallel connections.
