Always make sure to read the manufacturer’s instructions and use the correct battery for your RC car.

Choose the Right Battery



When choosing a lipo battery for your RC car, one of the most important factors to consider is its capacity, measured in milliampere hours (mAh). The capacity determines how long the battery will last before needing to be recharged. If your car has a high power motor, you will need a battery with a higher capacity to ensure it runs for a reasonable amount of time. However, a higher capacity battery will also be heavier, so you need to find the right balance between capacity and weight for your specific car.


The voltage of the battery is also important. Most RC cars run on either 7.4V or 11.1V batteries, although some may require a different voltage. It is essential that you choose a battery with the correct voltage for your car to ensure it runs smoothly and efficiently. Using the wrong voltage battery can damage your car or cause it to perform poorly.

C Rating

C Rating

The C rating of a lipo battery refers to the rate at which it can discharge its energy. A higher C rating means the battery can deliver more power, allowing your car to accelerate faster and reach higher speeds. However, using a battery with too high a C rating can also damage your car’s electronic components. As a general rule, a C rating of between 20 and 30 should be sufficient for most RC cars.

Brand and Quality

When choosing a lipo battery for your RC car, it is also important to consider the brand and quality of the battery. Choose a battery from a reputable manufacturer that has a good track record for producing high-quality batteries. Poor quality batteries can be dangerous, particularly if they are overcharged, and can damage your car’s electronic components.



Choosing the right lipo battery for your RC car is essential to ensure it runs efficiently and safely. Consider the capacity, voltage, C rating, and brand and quality of the battery before making your choice. Always follow the manufacturer’s instructions for charging and using the battery to minimize the risk of damage or injury.

Preparing the Car for Installation

Clean the Car

Before installing the lipo battery, make sure your car is clean and free of dirt, debris, and oil residue. Use a soft damp cloth to clean the surface of the car. Avoid using abrasive materials, as they can scratch or damage the surface of your car.
