Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
Lithium battery series and parallel: There are both parallel and series combinations in the middle of the battery pack, which increases the voltage and increases the capacity. Such as 4000mAh, 6000mAh, 8000mAh, 5Ah, 10Ah, 20Ah, 30Ah, 50Ah, 100Ah and so on. Take 48V 20Ah lithium battery pack as an example Lithium Battery PACK
Due to the limited voltage and capacity of single batteries, series and parallel combinations are required in actual use to obtain higher voltage and capacity in order to meet the actual power supply needs of the equipment. Lithium battery in series: the voltage is added, the capacity remains the same, and the internal resistance increases.
Lithium batteries in parallel: the voltage remains the same, the capacity is added, the internal resistance is reduced, and the power supply time is extended. Lithium battery series and parallel: There are both parallel and series combinations in the middle of the battery pack, which increases the voltage and increases the capacity.
The four lithium-ion cells of 3.6 V connected in series will give you 14.4 V, and this configuration is called 4S because four cells are connected in series. Figure 3. Series configuration. The number of cells can be varied according to the voltage of a single cell.
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.
