Step 2: Test the voltage

The +ve of the first battery should go into the +ve probe of the voltmeter. Then, the -ve of the second probably should be connected to the -ve of the voltmeter. Check if the reading is 26+ volts.

Note: You should fully charge both batteries before the conversion process.

Step 3: Install the batteries to the motor

With the terminals facing up and the needed modification to fit the two batteries, remove the voltmeter probes and install the batteries into the vehicle.

Step 4: Test drive

If everything is done correctly, the voltage upgrade should work well. Now, time for the test drive.

The 24-volt power wheels conversion will significantly increase the power capabilities of the ride-on vehicle. Make sure that your child is old enough to handle it. Watch over them while they are driving the converted toy car.

Frequently Asked Question

How To- Power Wheels 12V to 24V Conversion

When you modify a power wheel, you might have some questions in mind. Those who are not familiar and are doing this for the first time often have similar questions. Here, we will answer some frequently asked questions to help with your ride-on vehicle conversion.

How many volts can a 12v power wheel handle?

Most ride-on vehicles sold in the market use 12v batteries; thus, it is often the standard unit used for conversion. For this vehicle, it can handle an upgrade from 18 volts to 24 volts. With the modification, you are increasing the speed and power of the toy car without putting too much strain on the gears and motors.

Can you use a 24v battery on a 12v power wheel?

You can, but the 24v battery is often too much for a 12v power wheel. It can take a toll and burn the vehicle’s motor. The 12v motor with a 24v battery can last for only two to three months. It would be best to upgrade the engine when you upgrade the batteries for a ride-on vehicle that is safe for your kid to use.

Can you use a car charger to charge a power wheel?

Yes. You can modify the car charger, rig up the connector, and charge your power wheel with a car battery. It is an easy project if you have knowledge and experience dealing with vehicles.

What is the difference between 12v and 24v power wheels?

The main difference between the two is their power capabilities. The higher number of volts is more powerful and faster. Choosing a suitable toy car is based on this and the age of the toddler. Ensure that you follow the recommended age in the product description for a safe and enjoyable driving experience for the kids.

Will a 12v charger work on a converted 24v power wheel?

A charger for 12v is best used on a 12v battery. For a 24v converted power wheel with two 12 volts batteries in a series, it is best to charge them separately with 12v chargers. That way, you can make sure that each of the batteries is charged completely. It is not possible to charge both batteries simultaneously by simply plugging a single 12v charger.

How long do power wheel batteries last?

It can vary depending on the power requirements of the vehicle’s motor. A 12v battery can last for approximately two to four hours which is often similar to the 24v battery. On the other hand, 6v can only hold enough for 45 to 60 minutes of use.
