What Is 3S and 4s in RC Car?

A RC (Radio Controlled) car is a miniature vehicle that is connected to a remote controller and operated by manipulating the switches on the controller. RC cars come in many varieties, from small cars designed for children to full-sized replica race cars. The most popular types of RC cars are those that run on electric motors, but there are also some versions powered by gasoline engines.

The term 3S and 4S refer to the number of cells used in the battery pack of an electric motor-powered RC car. A 3S battery pack consists of three LiPo cells wired in series, while a 4S battery pack consists of four LiPo cells wired in series. The higher number of cells in a battery pack results in increased power output, allowing for higher speeds and longer run times.

The voltage output of LiPo batteries increases as more cells are added, so a 4S battery pack will provide around 14.8 volts compared to 11.1 volts provided by a 3S battery pack. This higher voltage allows an electric motor-powered RC car to reach much greater speeds than those powered by 3S batteries.

However, it should be noted that while 4S packs offer more power and speed than 3S packs, they also require more maintenance due to the additional cells. It is important to ensure that all LiPo cells are balanced correctly before using them in order to maximize performance and protect against potential damage.

In conclusion, 3S and 4S refer to the number of LiPo cells used in an electric motor-powered RC car’s battery pack. A 4S setup provides significantly more power and speed than a 3S setup but requires extra maintenance due to the additional cells. Understanding how these two configurations work is essential for getting the most out of your RC car experience.
