How Much Voltage Does an RC Car Need?

If you’re looking to get into the world of RC cars, you may be wondering how much voltage your car needs. The answer is not as straightforward as it seems. The amount of volts needed for an RC car depends on several factors, such as the type of motor, battery power, and other components.

Let’s take a look at what you need to know about voltage in your RC car.

The Type of Motor Matters

When it comes to choosing the right voltage for your RC car, it all starts with the type of motor you choose. Brushless motors are more powerful than brushed motors and require more voltage to operate effectively. Generally speaking, brushless motors require between 7-8 volts per cell while brushed motors typically need 4-6 volts per cell.


Battery Power Matters Too

Another factor that affects the amount of voltage your RC car needs is battery power. Batteries come in various sizes and capacities, which can play a role in determining how much power you need for your vehicle. Generally speaking, the higher the capacity of your battery pack, the more voltage it will need—but this isn’t always true; some batteries have a lower capacity but still require more power than others due to their design or components used. It’s best to do research on the specific model of battery you plan to use in order to determine its exact requirements.


Other Components Affect Voltage Needs Too

Finally, other components like servos and speed controllers can also affect your RC car’s required voltage level. Servos usually require between 5-7 volts while speed controllers tend to require up to 12 volts or more depending on their size and design. It’s important to check each component carefully before deciding on a specific voltage level for your RC car as these components can significantly impact how much power is required for optimal performance from your vehicle.



Voltage plays an integral role in powering an RC car successfully so it’s important that you understand how much power is needed for optimum performance from your vehicle before purchasing any parts or components. Your choice of motor type, battery capacity, and other components are all factors that can affect how much voltage is required for successful operation so make sure to do some research before making any decisions! With a little bit of knowledge and preparation, you can find just the right amount of voltage for your RC car and enjoy hours upon hours of fun driving around with friends!
