How much amperes a power wheel draws will depend on the power rating of the power wheels motor and the voltage of the battery the power wheels car is using. Generally, the higher the wattage, the higher the amps drawn. The formula to calculate this is below.

Have you ever wondered exactly how many amps your Power Wheels draw? If so, this is the post for you.

We will go in-depth and answer this and a few other frequently asked questions on power wheels amps, as well as power wheels battery amps.

How Many Amps Does a Power Wheels Draw?

The amperage a Power Wheels vehicle uses is proportional to the voltage of the battery it runs on. Wattage is directly proportional to current consumption.

For instance, if the motor is rated 1000W and the battery is a 24V one, you can calculate the amperage as follows:

Power (P) is given in Watts. Our power here is 1000W

Voltage is given in Volts (V), which is 24V

Current (I) is given in Amperes, which s what we are calculating.

So, Current, I = Power, P divided by Voltage, V

I = P/V

I = 1000W/24V

= 41.67A

So this particular Power Wheels car will draw 41.67 amperes. It, therefore, follows if you want to decrease the amps drawn, you will have to change the motor to one with a smaller wattage rating or change the battery to one with a higher voltage rating.

You can also add another similar battery to double the voltage. Note, however, that this may require that you make a few adjustments to the wiring of the car so that everything runs fine.

How Many Amp-Hours Is A Power Wheels Battery?

To know the amp-hours of your Power Wheels battery, you will need to know the current drawn from the battery and the time it takes for the battery to discharge, say, completely.

So if the current, I, drawn from the battery is, say, X, in time T, the amp-hour C will be calculated s follows:

C =XT

For example, if your Power Wheels car draws 28A of current and it runs for 1.5 hrs until the battery is drained, the amp-hour of the battery is:

C = 28A x 1.5 Hours

C = 42 amp-hour

Consider Your Battery Cycle

It’s not a good idea to fully drain a battery during each charge cycle. For instance, when intending to use a lead-acid battery for several cycles, don’t run it past 80 percent of its charge.

You want to leave 20 percent in the battery. This not only increases the number of cycles you’ll get but also allows the battery to degrade by 20% before the performance starts to fall short of the design specifications.

The lead-acid battery will be different from Lithium-Ion Battery.

Power Wheels Amp FAQs

Does the amp-hour of the battery affect the performance of Power Wheels cars?

Yes. The amp-hour rating indicates the Power Wheels vehicle’s carrying capacity. If you’re in the market for a new battery for your Power Wheel, get one with an amp-hour rating that’s sufficient not only for all the attachments you plan to use at once but also for any future additions.
Keep in mind that the batteries you typically purchase to replace the ones you were given are typical of considerably higher quality. You could only double-check that the amps are higher.

How many amps does a 24v Power Wheels car draw?

As discussed, it depends on the power rating of the motor and the voltage of the battery used. Basically, the higher the wattage, the higher the amps drawn.

Is a 1000W Power Wheels car faster than a 1200W one?

When comparing the power ratings of Power Wheels cars, the higher the rating, the more powerful its acceleration. But speed depends on other factors as well, some of which include weight and design.
There are lots of ways to upgrade your Power Wheels for it to go faster.

What are Power Wheels amps?

Amperes or amps measure the amount of current drawn from a source to run an accessory in your power wheel car. This will determine how long it can operate without draining out completely if you don’t have another battery for backup.

Is a 12v Power Wheels car more powerful than 24V one?

The voltage rating of the battery will determine how much wattage can be drawn by your power wheel. Generally, higher voltages mean that there’s less resistance to current flow, which results in quicker acceleration and speeds for the vehicle.
A lower voltage rating means lesser amperes are drawn at once, meaning reduced torque on starting up, but they last longer.
Can you put two batteries from a 12v power wheel into a 24v one? If so, how do you wire it correctly to work without shorting out or blowing fuses?
Yes. This is possible, but you have to do some minor twerks on the Power Wheels wiring system so it keeps working properly.

What is the difference between a 12V and 24V motor?

There are a few differences between a 12V and 24V motor for Power Wheels cars.
First of all, the voltage rating determines how much wattage can be drawn by your car’s accessories at once while operating under normal conditions.
A higher voltage means that there is less resistance to current flow, so even though more amperes are drawn at once, there will still be better acceleration and speeds because of this fact.
However, if you don’t have other batteries in place or are wired up correctly with it as backup, using an accessory with too high voltages might result in shorter life spans for both the battery pack and the engine (motor).
A lower voltage rating, on the other hand, reduces torque during starting but helps increase runtime since they draw lesser currents which allows them to last longer.
Additionally, the internal construction of a 24V motor is different from that of a 12V one in terms of the number and windings of coils used to get it started as well as its performance.

Conclusion

Hopefully, you can now easily calculate the amps your Power Wheels car draws. And now that you know how to get the amp-hour of your Power Wheels battery, it should be easier for you to change things around and make the toy more powerful or less powerful as needed.

If you are interested in purchasing a higher amp battery these are the ones we recommend.
