How long should an RC battery last? 

Three things determining how long RC car batteries would last include the RC battery’s model, type, and manufacture. When choosing a battery for your RC car, you also need to consider the cell number (S) and mAH level. These factors will help you determine the battery runtime and cycle. 

The three most commonly used RC car batteries are NiMH, LiPo, and NiCD batteries. 

  • NiMH batteries have average runtime between fifteen to twenty minutes on a single charge. On the other hand, their charge cycle typically ranges between 700 to 1000. 
  • LiPo batteries can run for about thirty minutes charge once, and they generally have a 300charge cycle. 
  • NiCD batteries will last for about twelve to fifteen minutes and have a charge cycle between 100 to 300 cycles, after which its performance drastically declines. 

Regardless of this, RC batteries should be able to run up to thirty minutes on a single charge, with a charge cycle between 100 to 1000 charges. After this period, you can dispose of them since their performance and charge decline. 

Can you make your RC car batteries last longer?

When RC batteries pass their lifespan, they will no longer charge as they deteriorate. Once this happens, they start to swell and might damage your RC car if not replaced. To avoid this situation, you need to ensure proper care and maintenance as it helps the batteries last longer. 

If you own RC batteries and want to make them last longer, do this:

  • Don’t overcharge your battery.
  • Don’t wait until the battery is dead before charging it. Instead, charge immediately once it gets low.
  • Learn proper storage techniques to keep the battery safe from environmental conditions.
  • Always keep the RC battery dry and clean.
  • In between the charging and discharging period, allow the battery to rest.
  • If you plan to use the battery in the cold, make sure to preheat it before using it.

Does a bigger battery mean longer drivetime?

Most RC car enthusiasts believe that the bigger the RC battery, the longer they last when run. To answer this question, you need first to determine what is meant by a bigger battery. 

Sometimes, when people say a bigger battery, they mean that battery has larger voltage output or mAh rating. Other times, some may assume that a bigger battery refers to the RC car’s battery physical size. 

If the physical size determines the average drive time of the RC car, it means all batteries will have the exact specification. Hence, there will be no advantage of a physically bigger battery. In fact, the smaller size RC batteries will better suit your RC car and offer longer drive time. 

Large batteries may cause uneven weight distribution, thereby making the car move around due to their added weight and the vibration they cause when the car moves. In this situation, the battery will heat and damage quickly, causing the acidic electrolyte particles to leak and damage other electronic parts in the engine compartment. 

On the other hand, if a bigger battery implies a higher voltage rating than the standard 8V, it may also damage the RC car, which means shorter drivetime for you. 

First, a physically bigger battery may not fit the car’s battery slot. Still, if you manage to fit this big-size battery in the battery compartment, the higher voltage rating may cause more damage than increasing your RC car’s runtime. Why? RC cars are designed to house a high voltage rating at 8V on average.
So, a 10V or 12V battery may cause the RC car to break when driving, meaning short drivetime.

However, if your idea for a bigger battery has different specifications and these specifications have a higher value, you can enjoy a longer drive time. Why? The battery is bigger in terms of specification. 

For RC car batteries, we use the mAH rating. This rating measures the RC car battery’s capacity to provide a particular magnitude of current for some amount of time. For instance, when a battery has a 40Ah or 20AH rating, the battery can provide a current of 40A for 1 hour and 20A for 2 hours. 

So, suppose you’re wondering whether a bigger battery will mean a longer drivetime. In that case, the simple answer is that the more the mAh rating in the cell’s battery pack, the more your RC car runs for more extended hours since a higher mAH means the battery can store more energy. 

Are there differences in drive time for each type of RC car? 

Drivetime mostly depends on the type of RC car model that you use. Nitro-powered RC cars usually come engineered with a 110-125cc fuel tank, lasting between 20-25 minutes, depending on how fuel is consumed.

On the other hand, electric RC cars are powered by RC batteries such as LiPo and NiMH. The runtime can vary with the built-in battery capacity and car endurance capacity.
For instance, a beast truck that uses a battery with a capacity of 1500mAh can last up to 25-30minutes, and a larger capacity battery can run a little longer. 

On the other hand, Rock crawlers can last longer on this same 1500mAH battery capacity since they are usually slow and won’t cause the battery energy to deplete rapidly. 

In essence, drivetime differs by the type of car you use. RC cars with higher speed and torque capacity of servos will consume more battery and hence lesser drivetime. 

Does 6s or 4S have a longer life than 2S?

The amount of current a battery produces determines how long it will last.
A 6s battery can run for 50mins while the 4s can offer drivetime between 30 to 40mins on a single charge. On the other hand, a 2s battery can run between 10 to 15mins. 

This means that 6s and 4s batteries last longer than the 2s counterparts. 

RC car batteries shelf life (and which has the longest shelf life)

All RC batteries have a shelf life before they lose their relevance. 

  • NiCD batteries have an average shelf life of one to three years, 
  • NiMH batteries’ shelf life ranges between three to five years, 
  • LiPo batteries have a shelf life of two to four years.

Final Thoughts

Every RC owner and enthusiast needs to know that RC car batteries are the source that ensures the RC car performs exceptionally and lasts long on the track. For this reason, you need to learn how to store, charge, and use RC car batteries properly. You do not want to spend an exorbitant sum finding a replacement for your RC car battery. Proper care and maintenance play a vital role in making your RC car batteries last longer.
