What size is a 3S LiPo?
Quick Guide to 3S LiPo Battery Sizes
A 3S LiPo battery, or Lithium Polymer battery with three cells in series (3S), is commonly used in remote-controlled (RC) vehicles and drones. The size of a 3S LiPo varies depending on its capacity and intended use, but it generally falls within specific dimensions that are crucial for fitting into RC devices.
Compact 3S LiPo Batteries Demystified
The compact nature of 3S LiPos makes them ideal for RC applications where space is at a premium. These batteries typically range from about 50mm to 80mm in length and width, with thickness varying between 16mm and 24mm.
Size Matters: 3S LiPo Dimensions
The dimensions of a 3S LiPo battery are critical for ensuring proper fit within RC vehicles or drones. The standard size is approximately:
- Length: 50mm to 80mm
- Width: 40mm to 60mm
- Thickness: 16mm to 24mm
What You Need to Know About 3S LiPos
A 3S LiPo battery consists of three cells connected in series, providing a nominal voltage of 11.1V and a capacity ranging from 500mAh to over 2000mAh. The higher the capacity, the longer the runtime but also the larger the size.
3S LiPo: The Ideal Size for RC Drones
The ideal size of a 3S LiPo battery for RC drones depends on factors such as motor power requirements and flight time expectations. A typical 3S LiPo used in small to medium-sized drones measures around:
- Length: 60mm
- Width: 45mm
- Thickness: 20mm
Small but Powerful: 3S LiPo Battery Size
The compact size of a 3S LiPo battery belies its power. Despite being small, these batteries can deliver high discharge rates and provide sufficient energy to operate various RC devices efficiently.
Decoding Voltage and Wattage in 3S LiPo
A 3S LiPo battery has a nominal voltage of 11.1V when fully charged and discharges down to around 9.6V before needing recharging. The wattage (W) can be calculated by multiplying the voltage with the capacity, e.g., 11.1V * 2000mAh = 22.2Wh.
Choosing the Right Size for Your 3S LiPo Battery
Selecting the right size of a 3S LiPo battery involves considering your device's power requirements and available space. A larger capacity means more runtime but also greater bulk, while smaller batteries offer less energy but are easier to fit.
Common Sizes of 3S LiPo Batteries Today
Todays common sizes for 3S LiPo batteries include:
- Small Capacity (500mAh - 1000mAh): Dimensions around 45mm x 35mm x 16mm.
- Moderate Capacity (1200mAh - 1800mAh): Dimensions approximately 60mm x 45mm x 20mm.
- Larger Capacity (2000mAh and above): Dimensions around 75mm x 50mm x 22mm.
The Best Fit: Selecting a 3S LiPo Size
To select the best size for your 3S LiPo battery, consider:
- Device Compatibility: Ensure the battery fits within your RC device.
- Power Requirements: Match the capacity to the power needs of your device.
- Runtime Expectations: Larger capacities offer longer runtime but may be bulkier.
