110 scale RC drift cars commonly use two main types of batteries Nickel Metal Hydride (NiMH) and Lithium Polymer (LiPo) batteries. Each type has its own characteristics and considerations. Here’s an overview of these battery types
Nickel Metal Hydride (NiMH) Batteries
NiMH batteries have been widely used in RC applications for a long time. They offer several advantages
Cost-effective NiMH batteries are generally more affordable compared to LiPo batteries.
Availability NiMH batteries are readily available in various capacities and configurations.
Safety NiMH batteries are generally considered safer and less prone to thermal runaway or swelling compared to LiPo batteries.
Forgiving Charging NiMH batteries are more forgiving when it comes to charging, and they can be charged with standard NiMH battery chargers.
However, NiMH batteries have some limitations
Lower Energy
Density NiMH batteries have a lower energy density, which means they have less energy storage capacity compared to LiPo batteries of the same size. This results in shorter run times.
Self-Discharge
NiMH batteries have a higher self-discharge rate, meaning they lose their charge over time, even when not in use. Regular charging or conditioning is necessary to maintain performance.
Voltage Drop
NiMH batteries have a voltage drop during discharge, which can result in a decrease in performance as the battery voltage decreases.
Lithium Polymer (LiPo) Batteries
LiPo batteries have become increasingly popular in RC applications due to their higher energy density and performance advantages. Here are some key features of LiPo batteries
High Energy
Density LiPo batteries have a higher energy density compared to NiMH batteries. This means they can store more energy in a smaller and lighter package, resulting in longer run times.
Higher Voltage
LiPo batteries provide a higher voltage output, typically 3.7 volts per cell. This higher voltage allows for improved performance, higher speeds, and more power to the motor.
Lighter Weight
LiPo batteries are generally lighter compared to NiMH batteries of the same capacity, reducing overall vehicle weight and improving handling.
Consistent Power Output
LiPo batteries deliver consistent power output throughout the discharge cycle, providing consistent performance until they reach a low voltage cutoff.
However, LiPo batteries have some considerations
Handling and Safety
LiPo batteries require careful handling and proper charging procedures to prevent damage, swelling, or even fire hazards. It’s important to use dedicated LiPo battery chargers and follow safety guidelines.
Voltage Cutoff
LiPo batteries have a recommended minimum voltage cutoff to prevent over-discharging, which can damage the battery. It’s important to monitor battery voltage during use and ensure the cutoff voltage is not reached.
Storage
LiPo batteries require proper storage to maintain their performance and longevity. They should be stored at a proper voltage level and in a cool, dry environment.
When choosing between NiMH and LiPo batteries for your 110 scale RC drift car, consider factors such as your budget, desired run time, performance requirements, and safety precautions. Ensure that your RC drift car’s electronics, such as the ESC, are compatible with the battery type you choose. Always follow the manufacturer’s recommendations and guidelines for proper use, charging, and storage of the chosen battery type to maximize performance and safety.
