How Big of a Battery Can I Put in My RC Car?

When it comes to RC cars, battery size matters. The size of the battery affects how long your car can run for, how fast it can go, and even the type of terrain it can tackle.

With so many variables to consider, it can be difficult to decide what size battery to put in your RC car.

The first step in determining the size of the battery you need is to determine what type of RC car you have. Different types of cars require different sizes of batteries.

If you have an off-road car, for example, you’ll need a larger battery than if you have an on-road car. This is because off-road cars require more power and speed than on-road cars.

The next step is to look at the current battery that’s installed in your car and see what kind of performance it gives you. This will help give you an idea of how much power and speed your car needs from a new battery. If your current battery isn’t giving you enough power or speed, then you may need a larger one.

Once you know what type of RC car you have and how much power and speed it needs from a new battery, then it’s time to start shopping for one. There are many different sizes and types of batteries available on the market today, so make sure to do some research before making a purchase.

Safety First

When shopping for a new battery for your RC car, make sure that it meets all safety standards and that it’s compatible with your model. Overloading the system with too big of a battery could cause damage or even fire if not installed correctly.


In conclusion, when deciding what size battery to put in your RC car consider the type of vehicle, its current performance level and make sure that whatever size chosen meets all safety standards before purchasing. Doing so will ensure that your RC car will continue running smoothly for years to come!
