What is a 3S LiPo Battery?

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, while “LiPo” is short for lithium polymer, a type of rechargeable battery known for its lightweight, high power, and flexibility in form factor. Sometimes it’s also referred to as “LP.”

How Many Amps Does a 3S LiPo Put Out?

The current (amps) that a 3S LiPo battery can output depends on its capacity (measured in mAh) and its discharge rating (C rating). For example, if a 3S LiPo has a capacity of 2200mAh (2.2Ah) and a 25C discharge rate, it can provide 55 amps, calculated as follows:

This means the battery can theoretically supply up to 55 amps under load.

How Long Does a 3S LiPo Battery Last?

The runtime of a 3S LiPo battery depends on its capacity, the load, and how much current the application draws. For instance, if a battery with a capacity of 2200mAh (2.2Ah) powers a device drawing 10 amps, the estimated runtime would be 13.2 minutes, calculated as follows:

The actual runtime may vary due to factors like battery efficiency and discharge characteristics.

What Is the Difference Between a 3S and a 4S LiPo Battery?

The primary difference between a 3S and 4S LiPo battery is the number of cells connected in series:

• 3S LiPo Battery: 3 cells connected in series, providing 11.1V.
• 4S LiPo Battery: 4 cells connected in series, providing 14.8V (4 x 3.7V).

A 4S LiPo has a higher voltage and can deliver more power to a system, but it’s also heavier and might require a motor and electronic speed controller (ESC) rated for higher voltages.

How Many Times Can You Recharge a LiPo Battery?

A LiPo battery can typically be recharged 300 to 500 times, depending on factors such as charging practices, discharge rates, and overall battery care. Proper maintenance, like avoiding over-discharging and storing at the correct voltage, can extend the battery’s lifespan.

What is the capacity of 3S LiPo batteries?

The capacity of 3S LiPo batteries can vary depending on the specific model and manufacturer. Typically, 3S LiPo batteries come in a range of capacities, usually measured in milliamp-hours (mAh). Common capacities include:

• 1000mAh to 1500mAh: Suitable for smaller RC models like drones and cars.
• 2200mAh to 3000mAh: A popular range for mid-sized drones, planes, and RC cars.
• 4000mAh to 6000mAh: Used for larger models or applications requiring longer runtimes.
• Above 6000mAh: Typically used for high-performance applications such as large RC vehicles, boats, or custom electronics projects.

The capacity determines how much charge the battery can hold, affecting the runtime of the device it powers. Higher capacity batteries will provide longer runtimes but may be heavier or bulkier.
