Introduction to 4S Batteries
A 4S battery refers to a battery pack composed of four single cells connected in series. In the field of lithium - ion batteries, the "S" represents a series connection. When cells are connected in series, the voltage of the battery pack is the sum of the voltages of each single cell. For common lithium - ion cells with a nominal voltage of 3.7V, a 4S battery pack will have a nominal voltage of about 14.8V (3.7V×4).
4S batteries are widely used in various applications. In the field of electric vehicles, they can be used as auxiliary power sources or in some small electric vehicle models. In the field of unmanned aerial vehicles (UAVs), 4S batteries can provide sufficient power to support the flight of medium - sized UAVs, enabling them to have longer flight times and better performance. They are also used in some high - power portable electronic devices, such as high - end power tools, to meet the high - power requirements of these devices.
