A single LiPo cell has a nominal voltage of 3.7 volts. When two cells are connected in series, their voltages combine. Thus, a 2S LiPo battery has a nominal voltage of 7.4 volts (3.7V + 3.7V). However, when fully charged, each cell can reach up to 4.2 volts, making the total voltage of a fully charged 2S battery 8.4.

In addition, different types of lithium batteries may have different charging requirements. For example, lithium-ion and lithium-polymer batteries may require different chargers due to their different chemistries. ...
By connecting the 1152 mAh and 871 mAh cells in parallel you would get the equivalent of a 2023 mAh cell, while connecting the 1121 mAh and 931 mAh cells in parallel would yield the equivalent of a single 2052 mAh cell. You could then put these two parallel groups in series, to yield a slightly imbalanced 7.4V 2023 mAh pack.
LiPo batteries are capable of catching fire if not used properly - they are much more delicate than the older NiMH/NiCd batteries. The problem comes from the chemistry of the battery itself. Lithium-Polymer batteries contain lithium, an alkali metal, which reacts with water and combusts. When heated, Lithium also combusts when reacting with oxygen.
But this only works if you have the same voltage. For instance, you can''t pair 6V and 12V batteries in series.Doing so may destroy the batteries involved. If the voltage matches, you can connect multiple batteries in series by running a line from one battery''s negative terminal to another battery''s positive terminal.
It is easily to answer" Why lithium cells need parallel and series?. As we have explained above, Due to the limited voltage and capacity of single cells, in order to meet the actual power supply needs of the equipment, battery pack manufacturers always use a combination cells of series and parallel to obtain higher voltage and capacity.
