Can a Battery Make an RC Car Faster?

For those with an RC car hobby, one of the most common questions is “Can a battery make an RC car faster?” The short answer is yes, but it’s important to understand how. Generally speaking, the type of battery used in an RC car can have a significant impact on its performance.

The most common type of battery used in RC cars is nickel-cadmium (NiCd) or nickel-metal hydride (NiMH). Both types of batteries are capable of providing decent power, but they have their limitations.

NiCd batteries generally produce lower voltages than NiMH batteries, meaning they’re less efficient in terms of speed and power. This makes them better suited for low-speed applications such as crawling or rock racing.

Lithium Polymer Batteries

Lithium polymer (LiPo) batteries are the latest and greatest in battery technology for RC cars. LiPo batteries offer higher voltages than both NiCd and NiMH batteries, making them ideal for high-performance applications such as racing. LiPo batteries also tend to be lighter than other types, resulting in a reduction in overall weight which helps to improve acceleration and top speed.


So to answer the question: yes, a battery can make an RC car faster. The choice of battery can have a significant impact on performance, with LiPo batteries being the best choice for those who want maximum speed and power. However, it’s important to consider other factors such as weight and cost when making your decision.
