Shop 4S LiPo Batteries and 14.8V RC Battery Packs
Explore 4S LiPo batteries at Aus Electronics Direct for compatible RC cars, trucks, aircraft and other hobby applications. Compare battery capacities, discharge ratings, connectors and dimensions to find a pack that suits your vehicle or equipment.
A standard 4S lithium-polymer (LiPo) battery has four cells connected in series and a nominal voltage of 14.8V. High-voltage (HV) LiPo batteries are also available and may have a different nominal voltage and charging limit. Always check the exact specifications of the battery you select.
How to Choose the Right 4S Battery
-
Voltage: Confirm that your equipment and electronic speed controller (ESC) support the battery's cell count and maximum charged voltage.
-
Capacity (mAh): Capacity affects the energy stored and potential runtime, but the battery must still fit your equipment and meet its weight requirements.
-
Discharge rating (C rating): Check that the battery can safely supply the current required by your motor and electronics.
-
Connector: Match the battery connector to your equipment, including options such as XT60, XT90, Deans or EC5 where available.
-
Dimensions: Compare length, width and height with the battery compartment before ordering.
-
Battery chemistry and charging: Use a charger with the correct battery chemistry, cell count and charging settings. HV LiPo packs require a charger and settings specifically suitable for HV batteries.
Compare the available 4S battery packs by their specifications before choosing a replacement or upgrade. Follow the manufacturer's instructions for charging, balancing, storage and safe handling.
Frequently Asked Questions About 4S Batteries
What does 4S mean on a LiPo battery?
4S means the battery contains four cells connected in series. A standard LiPo pack has a nominal voltage of 14.8V, although high-voltage LiPo batteries can have different nominal and maximum charging voltages.
Is a 4S battery the same as a 14.8V battery?
A standard 4S LiPo battery is commonly rated at 14.8V nominal. However, some high-voltage 4S LiPo packs have a different rating. Check the specific product label and specifications rather than relying on the 4S designation alone.
What voltage is a fully charged standard 4S LiPo battery?
A standard LiPo cell is typically charged to 4.2V, so a fully charged standard 4S LiPo pack reaches 16.8V. High-voltage LiPo batteries may have a higher permitted charging voltage per cell. Follow the battery manufacturer's specifications and use the correct charger mode.
How do I choose the right 4S battery capacity?
Compare the available mAh ratings, battery dimensions, weight and your equipment's power requirements. A higher capacity can provide more stored energy, but it may also increase battery size and weight. Actual runtime depends on power consumption and operating conditions.
What does the C rating mean on a 4S LiPo battery?
The C rating is a manufacturer's rating used to describe a battery's discharge capability relative to its capacity. Check the manufacturer's specifications and ensure the battery can meet the current demands of your setup. Do not select a battery on the C rating alone.
Can I use any 4S LiPo battery in my RC car or truck?
No. Verify that the vehicle, ESC and other electronics support the battery's cell count and maximum voltage. Also check the connector, dimensions, weight and discharge requirements before purchasing.
What charger do I need for a 4S LiPo battery?
Use a charger that supports four-cell LiPo packs and the specific battery type. Follow the manufacturer's instructions for balance charging and charging limits. An HV LiPo battery requires compatible HV charging settings.
