Self-Discharge Rate

When it comes to the self-discharge rate of NiMH and LiPo RC car batteries, both types tend to lose their charge when not in use. However, this rate varies depending on which type of battery you use. 

NiMH batteries tend to have a faster self-discharge rate than LiPo batteries. For NiMH batteries, the self-discharge rate is typically around 20-30% per month. This means that if you do not use the battery for a month, it will lose about 20 to 30 percent of its charge.

On the other hand, LiPo batteries have a much slower self-discharge rate than NiMH batteries. Typically, LiPo batteries self-discharge at a rate of 10-20% per month. This means that even if you do not use your LiPo battery for an entire month, it will still maintain 90 to 80 percent of its charge.

Overall, the self-discharge rate of NiMH RC car batteries is faster than those of LiPo batteries. However, LiPo batteries have the added benefit of being lighter and having higher capacity ratings than NiMH batteries. Thus, depending on your specific needs, you may want to choose either one for your RC vehicle. Ultimately, it is up to you to decide which type of battery is best suited for your RC car or truck.

Charge Cycles

NiMH batteries are known for their higher charge cycles, allowing users to recharge the battery multiple times without significantly decreasing its performance. A typical NiMH battery will last up to 1000 charge cycles before it needs to be replaced. LiPo batteries also have a long lifespan but not as long as NiMHs.

For those looking for a high-performance battery without breaking the bank, NiMH batteries may be a better option.

Storage and Safety

NiMH batteries are more resistant to overcharging, which is a common problem with LiPo batteries. NiMH cells do not require as much attention when it comes to storage, but can still become damaged if stored in too high of temperatures for extended periods of time. When storing NiMH batteries, it is important to keep them at room temperature or slightly cooler and to never discharge them completely.

LiPo batteries are more susceptible to overcharging, so it’s important to pay attention when charging them. They also require special storage requirements and should not be stored in temperatures above 25°C (77°F). LiPo batteries must also be kept away from any metal objects, as they can generate heat and cause a fire. When storing LiPo batteries, it is best to store them in a fireproof container or bag and to keep them at around 50-75% capacity. 

In general, all batteries should be stored away from extreme temperatures, direct sunlight, or any areas of moisture. This will help ensure that the battery remains in optimal condition for as long as possible. It is also important to check the voltage and discharge rate of your LiPo battery regularly, as this can help indicate any signs of damage or abnormal behavior. 

NiMH batteries are preferred for their safety features. Unlike LiPo batteries, NiMH batteries do not contain the volatile components found in lithium-polymer cells and therefore have a lower risk of shorting out or bursting into flames. They are also less prone to overheating, allowing them to be used in more extreme temperatures and environments. NiMH batteries can also be used for a much longer period of time without needing to be recharged, making them ideal for projects that require extended use. 

Additionally, NiMH batteries are more environmentally friendly than LiPo batteries as they contain no toxic materials and have an overall lower carbon footprint. While these advantages make NiMH batteries the clear choice for many applications, there are also some drawbacks that should be considered. NiMH batteries have a lower energy density than LiPo batteries, meaning they cannot store as much power in the same amount of space. This can be an issue when designing projects with limited space or weight considerations. Additionally, the battery life of NiMH cells is shorter than LiPo batteries and they must be recharged more frequently. 

Finally, it is important to make sure that you are using the correct charger when charging or discharging your LiPo battery. Using the wrong charger can potentially damage your battery or cause it to malfunction. It is always best to check with the manufacturer of the battery before charging or discharging, and to make sure that you are following their instructions.
