What is a 5S LiPo battery?

If you’re into RC vehicles, drones, or robotics, chances are you’ve come across the term 5S LiPo battery. But what exactly is it? A 5S LiPo battery is a lithium polymer battery pack made up of five cells connected in series. Each cell contributes to the battery’s total voltage and power. Why are these batteries so popular?

What is the internal resistance of a 5S LiPo battery?

Internal resistance is a measure of how easily energy flows through the battery. Lower resistance means better performance. Most 5S LiPo batteries have an internal resistance of 1–10 milliohms per cell. Why does this matter? Low resistance ensures efficient energy transfer and minimal heat buildup.

What is a C rating on a 5S LiPo battery?

The C rating tells you how quickly a battery can discharge its energy. Common ratings for 5S LiPo batteries are 1-10C, 20C, 30C, 50C, or higher. Here’s why it’s important: A higher C rating means the battery can handle more intense power demands. However, it also drains the battery faster and can lead to more heat generation.

Are 5s LiPo batteries compatible with XT60 or EC5?

To accommodate a variety of devices and applications, 5S LiPo batteries are equipped with different connectors, such as XT60 or EC5. This diversity ensures compatibility across a wide spectrum of electronic devices.

How many cells are in a 5S cell?

The “5S” designation tells you exactly how many cells are inside. In this case, five individual cells are connected in series (hence the “S”). This arrangement adds the voltage of each cell together, creating a total nominal voltage of 18.5V (3.7V × 5).
