Shop 5S LiPo Batteries and RC Battery Packs

Explore 5S battery packs at Aus Electronics Direct for compatible RC vehicles, aircraft and other hobby applications. Compare battery voltage, capacity, discharge rating, connector type and physical dimensions to find a pack suited to your equipment.

A standard 5S lithium-polymer (LiPo) battery contains five cells connected in series and has a nominal voltage of 18.5V. The maximum charging voltage depends on the battery type, so always check the manufacturer's specifications before charging or connecting a battery.

How to Choose a 5S Battery

• Voltage and cell count: Confirm that your equipment and electronic speed controller (ESC) support a 5-cell battery and its maximum charged voltage.

• Capacity (mAh): Compare capacity, weight and dimensions against the needs of your vehicle or device.

• Discharge rating: Check the manufacturer's discharge specifications against the current requirements of your setup.

• Connector: Verify that the battery connector is compatible with your equipment and that polarity is correct.

• Dimensions: Measure the battery compartment and compare it with the listed battery dimensions.

• Charging requirements: Use a charger designed for the battery's chemistry and cell count, following the manufacturer's charging and balancing instructions.

Before purchasing, check the specifications of the battery, charger and connected electronics to ensure they are compatible. Compare the available 5S battery packs to find an appropriate option for your application.

 

Frequently Asked Questions About 5S Batteries

What does 5S mean on a battery?

5S means the battery pack contains five cells connected in series. The total nominal voltage depends on the chemistry and specifications of the individual cells.

Is a 5S LiPo battery 18.5V?

A standard 5S LiPo battery has a nominal voltage of 18.5V. Its fully charged voltage is typically 21V, based on 4.2V per cell. Always check the battery label and manufacturer's charging specifications, especially for high-voltage LiPo packs.

Can I use a 5S battery in my RC car or truck?

Only if the vehicle, ESC and other electronics support the battery's cell count, operating voltage and maximum charged voltage. Also check the battery's size, connector, weight and discharge requirements.

How do I choose the right 5S battery capacity?

Compare the battery's mAh rating, physical dimensions, weight and the power demands of your equipment. Higher capacity can store more energy, but the battery must still fit and remain within the equipment's supported limits.

What charger do I need for a 5S LiPo battery?

Use a charger that supports five-cell LiPo packs and the exact battery type. Follow the manufacturer's charging and balancing instructions, and never use a charging mode that exceeds the battery's specified voltage limit.
