But a li polymer battery pack has a higher power & energy because of is composed of two or more li polymer battery cells put together in series to increase the voltage to 7.4V(2S1P),
Lithium Polymer battery packs are widely used in Radio Controlled (RC) airplanes among other things for their charge/weight advantages. So what I''ve drawn above as an example is a representation of a 4S3P
A 3S LiPo (Lithium Polymer) battery refers to a battery pack consisting of three 3.7V lithium polymer cells connected in series (not parallel). This series connection results in a total voltage of 11.1V (3 cells x 3.7V = 11.1V). In the context, “3S” stands for three cells in series, w...
The way everyone and their dog would do it is a boost regulator and a single 3.7V cell. Series cell combinations require a charge balancer, so that''s way more complicated than just having a boost regulator. The cells can be connected in parallel without much trouble if you need to – it''s the series connection that''s problematic.

3. Series-Parallel Connection. A series-parallel connection combines both configurations to increase both voltage and capacity. For example, connecting four 3.7V 100mAh
3. Cell management (BMS)costs: A series-first then parallel battery pack requires more sensors and wiring, with more BMS channels, resulting in higher costs. In contrast, a parallel-first then series configuration treats parallel-connected cells as one, making monitoring and BMS channels simpler and fewer, thereby reducing costs.

Series and Parallel configurations are popular in the lithium battery packs. Because, by combining multiple batteries in different configurations, we can easily achieve our required battery specification for the load requirements. The lithium batteries are good in charge and discharge rates. It is also smaller in size.
Series Connection: Batteries in Serial adds up the voltage, but current will be same. Parallel Connection: Batteries in Parallel adds up the capacity (mAh) or Current, but keeping the voltage same. Lithium batteries needs to be charged at it's precise voltage and current specifications. Otherwise, it may damage the battery and can cause fire.
3S Configuration: Similarly for 3S the voltage will be 11.1Volt. These configurations you can found in industrial equipment, drone, quadcopter batteries. Batteries connected in series internally.
