Determine the voltage required for your RC Car

  • Check your RC car’s manual to find out the acceptable voltage range for your battery.
  • Choosing a battery with the correct voltage can help protect the motor and prolong your RC car’s battery life.
  • Most electric RC cars operate on a 7.4V or 11.1V battery.
  • If you’re uncertain about the voltage required, consider contacting the manufacturer.

Determine the capacity you need

  • The capacity of a LiPo battery is measured in milliampere-hours (mAh).
  • Higher capacity batteries result in longer run times but also means a heavier battery.
  • Consider the type of RC car you have and how you plan to use it when choosing the capacity of your battery.
  • Most RC car manuals provide recommendations or guidelines for the capacity of the battery to use.
  • You can calculate the approximate runtime of your RC car by dividing the battery’s capacity by the current draw of the car.

Several battery manufacturers have interactive online tools to help you choose the right battery for your RC car. Websites like or provide a battery selector tool that lets you specify your RC car’s details and obtain recommendations for the best battery for your vehicle. Similarly, product listings on online stores such as and provide product specifications that can help you choose the right battery for your RC car based on your needs.

How do I know what size battery to get for my RC car?

To determine the correct size battery for your RC car, you need to consider the following factors:

  • The type of RC car you have
  • The voltage requirement of your RC car
  • The capacity (mAh) of the battery you need
  • The physical size of the battery that fits your car

To find the right battery, check your RC car manual or specs sheet to determine the voltage requirement and capacity needed. Then, choose a battery that matches those specifications and physically fits inside your RC car.

Alternatively, some RC hobby shops or websites such as or offer battery finder tools that can help you identify the ideal battery for your RC car based on its make and model.

Consider the discharge rate of the battery

  • The discharge rate refers to how quickly the battery can release its energy and is measured in C rating.
  • Choosing a battery with a higher C rating ensures that the battery can handle the amperage demanded by the motor and electronic speed controller (ESC).
  • Higher C ratings also mean the battery can deliver more power, resulting in faster acceleration and higher speeds.
  • However, higher C rated batteries may be more expensive than their lower-rated counterparts.
  • A discharge rate of at least 20C is recommended for most RC car applications, but this can vary depending on the type of vehicle and usage.

Here is a table that shows the recommended LiPo specifications for RC cars of different scales:

RC Car Scale Cell Count Capacity (mAh) Discharge Rate (C)
1/16 2S 800-1200 20-25C
1/10 2S 4000-5000 30-35C
1/8 4S 5000-7000 40-50C
1/5 6S 8000-10000 up to 100C

It is important to note that these are only general guidelines, and it might be different based on other factors and your RC car specifications. Several websites like provide high-quality LiPo batteries with different C ratings that you can choose depending on your requirements.

What is the C rating for different batteries?

  • The C rating is a measure of how quickly a battery can discharge its energy relative to its capacity.
  • A higher C rating means a battery can deliver more power in a shorter amount of time, but it may also reduce its overall lifespan.
  • Lithium polymer and lithium ion batteries typically have C ratings of 15-75C, while nickel-metal hydride batteries have lower C ratings of 1-2C.
  • It’s important to match the C rating of your battery to the requirements of your device to avoid damaging the battery or the device itself.

Determine the size and shape of your battery

  • The size and shape of LiPo batteries vary, and it is essential to choose the right size that will fit in your RC car.
  • Consider the dimensions and shape of the battery compartment of your RC car before purchasing a battery.
  • Some LiPo batteries may require additional modifications to fit your RC car, such as the addition of foam or plastic to create a better fit and prevent movement.
  • Additionally, consider the weight of the battery, as a heavier battery can affect the balance and handling of your RC car.
  • Several online stores like HobbyKing and Amazon provide a variety of LiPo batteries in various sizes and shapes suitable for RC car use.

What is the size of LiPo batteries?

LiPo batteries come in a variety of sizes, known as cell counts. The standard sizes available in the market are:

  • 1-cell: 3.7V
  • 2-cell: 7.4V
  • 3-cell: 11.1V
  • 4-cell: 14.8V
