How Long Do RC Car Batteries Last?

When it comes to RC cars, one of the primary power sources is an RC car battery (nitro fuel being the other).

Batteries or battery packs power radio-controlled automobiles, so it doesn’t matter if you’re a novice or an expert.

Those that participate in frequent racing recognise the importance of battery life in terms of overall run time.

Batteries and charging times affect the RC car’s ability to perform at a high level.

In general, RC car batteries last for 1-2 hours before they need to be recharged, however this varies depending on the size of the battery and how hard the vehicle is driven.

One to two hours is the maximum amount of time a rechargeable battery may last in an RC vehicle. Radio-controlled vehicle batteries are expected to last anywhere from three to six months. RC batteries have a short lifespan due to the constant charging at high speeds by the motors of the RC vehicles.

A battery’s lifespan depends on the kind of battery and how frequently it is charged( Source)

  • NiMH batteries have a life span of 3-5 years.
  • NiCD batteries have a lifespan of 5-7 years (with some batteries lasting much longer)
  • LiPo batteries have a 300-500 charge cycle life (discharge and recharge)

Incorrect charging or storage of RC batteries may lower the battery’s life span and reduce how long the battery lasts between charges, thus these values are only estimates.

In addition to the type, model, and manufacturer, a battery’s lifespan is influenced by how frequently it is serviced and how well it is maintained.

Battery types that may be recharged include alkaline and rechargeable.

The remote control runs on alkaline batteries, while the automobile moves on rechargeable batteries. The car and the remote control of certain low-cost RC cars are powered by alkaline batteries, although this is unusual.

Your RC car’s battery life depends on the type of pack you buy, the cell number, and the MAH number, among other considerations.

The battery life of an RC car and the time it takes to recharge it have a direct impact on its performance.

There are a few things to keep in mind before purchasing an RC battery: You may use this information to get a good RC battery.

Advantages of a NiMH Battery Pack: It is less expensive and simpler to use.
They can take a lot of abuse, so there is no need to be overly cautious with them.

The Drawbacks of a NiMH Battery Pack

Because the automobile is heavier than a LiPo battery, the power drops continuously as the car is driven, causing the car to accelerate more slowly.
On a full charge, it lasts around 15 minutes.

Tips on Extending your RC car Battery

There are a few things you can do to extend the life of your RC battery.

  • Never, ever overcharge your battery.
  • Do not wait until the battery is completely discharged before charging it; instead, plug in the charger and begin charging it as soon as it becomes depleted.
  • Properly store the battery.
  • Always keep your RC battery dry and clean.
  • Allow your RC battery to rest in between charging and draining cycles.
  • If you’re intending to use the battery in chilly conditions, warm it beforehand.

How Long Does It Take For A LiPo Battery To Charge?

It’s not uncommon for LiPo batteries to only be included with more costly ready-to-run RC models, but they’re more commonly purchased as a spare and installed on a home build or upgrade. 

Though more difficult to maintain, NiCad batteries offer some advantages over NiMH cells, and as a result, they are more popular among RC vehicle enthusiasts with a lot of expertise, especially those who compete in races.

Lithium-ion Polymer Battery Advantages

    • Lighter than a NiMH battery of similar size and capacity
      This battery has the potential to deliver significantly more power than a comparable MiMH battery.
    • keeps its power for a longer period of time in a stable condition, but when the battery runs out of juice, the power reduces swiftly.
    • The typical battery life is around 30 minutes, however some of the higher capacity models may last up to 2 hours.
    • LiPo batteries last an average of three times as long as NiHM batteries before needing to be replaced.

Lithium-ion Polymer( Lipo) Battery Drawbacks

    • Pricier than a NiMH of the same size and capacity
    • More difficult to properly maintain
    • The device has the potential to blow up if not charged and handled appropriately (although this isn’t going to result in a massive explosion).

How to Keep LiPo Batteries in Top Shape

You can make the same LiPo battery last longer than someone else’s by taking proper care of it.

Never deplete the battery 

Never deplete the battery to the point where it is completely depleted.
Batteries should never be overcharged (and never over-discharge them, too)
Avoid overcharging the battery by discharging at a higher current than it is rated for.

Do not allow batteries to overheat.

Store, charge, and discharge them in a fire-resistant LiPo safety bag, metal ammo box, or other fire-resistant container (it’s always worth investing $10 in a fire-resistant LiPo bag or ammo can).

What you should know about recharge cycles

While LiPos are convenient because they can be recharged, they do not last indefinitely.

“Most LiPo batteries have a maximum charge cycle of around 300,” said Bill Bradley

However, even 300 recharge cycles is overly optimistic. Bill stated that this is only true for higher quality batteries.  As a matter of fact, many LiPo batteries won’t even last 300 charges.

Why do we use LiPo batteries if they pose these risks?

Briefly put, they’re a force to be reckoned.

Compared to nickel cadmium batteries, which are typically used in cordless and wireless phones, a LiPo battery cell has nearly four times the energy density.

They are also four times more powerful than nickel metal hydride (NiMH) batteries, which are often used in digital cameras.

There is also a wide variety of lithium-ion batteries available. In addition to drones, the future generation of electric automobiles will be powered by these devices.

Our  Recommendation-RC Cars with Good Battery Life

MIEBELY RC Cars  comeswith  Two 7.4V 1000mAh Li-Po battery packs and a certified USB charger are included. You must remove the lithium battery from the truck before using it to better protect the Li-ion battery pack. This is, without a doubt, the vehicle for you.

Lithium-ion RC car batteries/Electric RC batteries

The majority of remote control cars now run on rechargeable lithium-ion batteries. If an RC model is to operate constantly, the battery life must be as long as possible.

As you are probably aware, batteries come in a variety of forms and sizes, with variable cell counts, and each model has its own power rating, capacity, and so on.

For newcomers to RC vehicles, the features may be confusing, leading them to select wasteful batteries or batteries that are just insufficient for their car.

RTR, or ready-to-race, refers to the pre-assembled nature of many RC vehicles.

In other words, the RC car arrives completely assembled and ready to drive straight out of the box.

However, some RC vehicles come without batteries, so you’ll need to purchase them as well.

Consult your vehicle’s owner’s handbook if you’re unsure which battery to purchase or what size to purchase.

The longevity of RC batteries is governed by the following factors:

  • Electric vehicle power ratings
  • a motor’s electrical speed and torque controls
  • The battery’s capacity

Our  Recommendation-2

BEZGAR HM101 Hobby Grade RC Car – you can buy a 2nd set of batteries + charger + usb cord from the company, to also increase play life : 

  • Dont run the gas while in mid air
  • Dont push against a wall
  • Dont run while upside down
  • it lasts about 15m in medium grass and 25 on concrete at max power.
  • Around 25 minimum power in grass, never charge the batteries when they’re warm, always take the batteries out when the truck seems sluggish, 
  • Do NOT increase the throttle to make up for it, it takes much… longer to charge

Battery life and RC motor power

The power rating of an RC car is stamped on the engine surface and is valid for both brushed and brushless motors.

When comparing the voltage of a battery to its KV rating, consider the number of revolutions per minute made by the engine (RPM). Because the engines of RC cars are permanently installed, they have a lower RPM.

The longest-lasting RC vehicle battery must have a higher voltage in order to generate greater RPM.

Additionally, a greater KV indicates a less efficient RC car when compared to one with a lower KV and the same voltage.

In comparison to high KV, low KV creates less heat at high voltage and has a lower maximum speed.

Always select an RC motor with an evenly distributed voltage range between the extremes. This enhances the performance of the most powerful RC battery.

The horsepower of the motor has an effect on the battery life. To avoid damaging your RC motor, ensure that the voltage on your RC car battery is right.

The battery’s capacity

Always look at the power rating on an RC battery before purchasing. The battery’s capabilities is measured in Milli Ampere Hours, or “power rating” (mAh). 

In other words, the longer the battery lasts, the more time your RC car can run before needing to be recharged.

When your RC car has a lot of power, it can go faster and stay in motion for longer.

Save RC Car’s Battery Life

Even if your radio controlled battery is fairly strong, there are a few things you can do to prolong its life.

Avoid driving in severely hot or cold temperatures, since this can diminish the battery’s life.

Extreme temperatures reduce the life of your battery by speeding up the rate of discharge.

In the winter, the battery will deplete more quickly, resulting in a greater than typical loss of power. The recommended temperature range for running an RC car is between 50 and 80 degrees Fahrenheit.

Avoid simultaneously hitting the throttle, since this can quickly deplete your RC battery. Accelerating rapidly depletes battery power in the same manner as driving rapidly depletes petrol.

Accelerate carefully, pushing and depressing the throttle as you go.

While driving slowly is not essential, you should avoid abrupt halts and starts. If you accelerate softly, your car’s battery will last far longer.

If the car is lighter, the battery life will be enhanced. The battery will last longer, and the RC car will perform better because there is less mass to push.

Additionally, you should inspect the condition of your tyres. If the tyres lack traction, the battery may discharge early if there is insufficient thread to hold them glued to the ground.

Changing the bushings in the RC car’s bearings, which minimise friction between the car’s moving parts, is another approach to increase the life of the battery.

Because bearings allow the shaft to rotate more freely than bushings do, they lower the amount of throttle necessary to accelerate the automobile.

Why is my RC car battery dying so quickly?

When you use your remote control car regularly, the battery life decreases. The engine of an RC vehicle continuously powers the battery at high speeds, quickly depleting it.

If you leave the battery in your remote control car without fully charging it, it will quickly drain.

RC vehicles’ motors drain energy and power from the battery, leading it to deplete more rapidly.

As a result, it is critical to charge your remote control vehicle’s battery prior to leaving it unattended for an extended period of time. When the engine of your remote control car is started but the vehicle is not in use, it begins to drain more power from the battery than is necessary, causing the battery to deplete more quickly.

Another aspect that contributes to the rapid demise of your RC vehicle’s battery is the manner in which you drive.

When you go in a stop-and-go pattern, the battery of your remote control car will deplete faster.

Driving in a stop-and-go fashion requires fast acceleration and deceleration. You must maintain a fluid driving style.

When you drive your remote control car with a battery that is not completely or almost fully charged, the battery will degrade much more quickly than you realise.

Using an out-of-date battery is another element that contributes to the rapid failure of your RC vehicle’s battery.

When you use an outdated battery in your remote control car, the battery begins to deteriorate, resulting in a shorter life.

Final Thought

Inspect your batteries to ensure they are in good condition and have been properly maintained.

If you manage your batteries properly, they will last far longer between charges and will also last significantly longer before needing replacement.

While LiPo batteries typically have a lifespan of 300-500 cycles, NiMH batteries have a significantly longer lifespan but do not provide as much acceleration or power.

Finally, you must decide what is best for you and if you want a longer-lasting battery or one with greater power, acceleration, and run time.
