Electric RC Car Battery: A Comprehensive Guide
Electric RC cars are becoming increasingly popular among hobbyists as they offer an exciting and engaging experience that can be enjoyed by people of all ages. One crucial component that determines the performance of an electric RC car is its battery. The battery provides the power necessary to drive the motor of the car and can have a significant impact on the car’s speed, acceleration, and handling. With the advent of newer and more advanced battery technologies, there are now several options available in the market when it comes to electric RC car batteries. Each type of battery has its advantages and disadvantages, making it essential for RC enthusiasts to choose wisely. In this article, we will discuss the different types of batteries used for electric RC cars, their characteristics, how to choose the right battery, and how to maintain it to ensure optimal performance and longevity of the vehicle.
Types of batteries
There are three main types of batteries used for electric RC cars, each with its strengths and weaknesses. These include:
- Nickel-cadmium (NiCad) batteries: These are the oldest and most common type of battery used in electric RC cars. While they are affordable and durable, they have lower capacity and are prone to memory effect, meaning they should be fully discharged before recharging to maintain their full capacity.
- Nickel-metal hydride (NiMH) batteries: These batteries offer a higher capacity than NiCad batteries and are less prone to memory effect. However, they have a lower discharge rate and are bulkier and heavier.
- Lithium polymer (LiPo) batteries: These batteries are the most advanced and offer the highest capacity and discharge rates. They are also lighter and more compact. However, they are more expensive and require special care to prevent overcharging or over-discharging, which can damage the battery.
Choosing the right type of battery for an electric RC car depends on several factors, including the desired performance level, budget, and frequency of use. Hobbyists can consult online reviews and product guides before making a purchase. Some popular websites for buying electric RC car batteries include Amazon, HobbyKing, and Horizon Hobby.
What batteries do RC cars use?
RC cars are powered mainly by rechargeable batteries. These batteries are designed to provide the necessary power for the electric motor that runs the car. There are different types of batteries that an RC car can use, which include:
- LiPo (Lithium Polymer) batteries- These batteries offer high power output and have a lighter weight, making them a popular choice in hobby-grade RC cars.
- NiMH (Nickel-Metal Hydride) batteries – These batteries are commonly used in entry-level RC cars due to their affordable price and decent power output.
- NiCad (Nickel Cadmium) batteries – These batteries have become obsolete as they are heavy, have poor power output, and are not environmentally friendly.
It’s important to note that the type of battery your RC car uses will depend on the type and size of the car. Consult the manufacturer’s specifications or the manual to know which battery to use.
If you’re in the market for RC car batteries, there are various online stores that sell a wide range of batteries from reputable brands such as Hobbyking, Ampow, and Venom Power.
Capacity and Voltage
When it comes to electric RC car batteries, capacity and voltage are the two most important factors that affect performance. Here’s what you need to know:
- Capacity is measured in milliampere-hours (mAh) and represents the amount of charge the battery can hold. The higher the capacity, the longer the battery can run before needing a recharge.
- Voltage is measured in volts (V) and represents the power output of the battery. The higher the voltage, the faster the car can go and the more torque it can produce.
- A higher capacity battery may have a longer runtime, but may also have a slower discharge rate, which can affect performance. Similarly, a higher voltage battery may produce more power, but may also generate more heat and put more strain on the car’s motor.
To choose the right battery for your electric RC car, consider the car’s weight, motor type, and driving conditions. A higher capacity battery may be necessary for a heavier car or for racing, while a higher voltage battery may be better suited for off-road driving. Some popular batteries for electric RC cars include the Traxxas Power Cell LiPo battery and the Venom NiMH battery.
The following table compares the key specifications of a NiCad, NiMH, and LiPo battery:
| Battery Type | Capacity (mAh) | Voltage (V) | Weight (oz) |
|---|---|---|---|
| NiCad | 1000-3000 | 7.2-9.6 | 4.9-12.3 |
| NiMH | 1600-5000 | 7.2-8.4 | 6.2-19.5 |
| LiPo | 500-8000 | 7.4-22.2 | 2.5-13.5 |
Charging
Properly charging your electric RC car battery is crucial for optimal performance and longevity. Here’s what you need to know:
- Before charging, make sure to read the instructions that come with your battery and charger, as the process may vary depending on the type of battery and charger.
- Many chargers come with a charging cable that connects the charger to the battery. Make sure the connectors are properly aligned and securely connected to avoid damaging the battery or charger.
- When charging, make sure to use a charger that is compatible with your battery type and voltage. Using the wrong charger can not only damage the battery, but can also pose a safety risk.
- Make sure to charge the battery in a well-ventilated area, away from flammable materials and electronic devices.
- Never leave a charging battery unattended, and make sure to unplug the charger once the battery is fully charged to avoid overcharging.
Some popular chargers for electric RC car batteries include the Venom Pro Quad Charger and the HTRC LiPo Charger. Investing in a high-quality charger can not only ensure safer charging, but can also extend the lifespan of your battery.
