Power Wheels DIY drill conversion saves money by using the 18v or 20v battery & charger from broken power tools. Simply cut the connector off the stock battery, add a 30 amp inline fuse between the red wire and connect it to the 3D printed adapter. Plug the new battery in and the speed will greatly increase.

This DIY Power Wheels battery alternative is a great way to recycle old power tool batteries. These lithium-ion batteries are one of the most toxic battery types in the world!

The battery can emit lead, mercury, and cadmium that pollute our landfills and cause hazardous waste for future generations.

This conversion gives the 18V or 20V power tool battery second life. We turn it into an 18V Power Wheels battery pack that will fit right inside your kid’s favorite toy car, truck, or jeep!

How to Perform a Power Wheels Drill Battery Conversion

Products needed will be listed above if needed. Parts and tools that will be needed to perform this are:

Parts

Tools

  • Wire crimper
  • Electrical Tape
  • Soldering Iron / 10ga Wire
  • Wire Strippers
  • Screwdriver

Step 1: Locate the Stock Battery

First, you want to locate the battery in your Power Wheels. It can be in the trunk, under the hood, or seat.

Once you locate it remove it from the car, you will have to unhook it from the wire harness, and there may be a bar holding it in place.

Step 2: Modify the Stock and Drill Battery

What we want to do next is cut the two wires that are attached to the stock battery as we need the connector plug.

Keep in mind this will make it so you can’t use the stock battery anymore.

We want to take the stock battery connector plug and attach it to the 3D Printed DeWalt battery adapter. To do this we will connect the negative (black) wire with the other black wire, to start we can just twist the wires together and use electrical tape.

You can go back over this part with crimpers later. For the positive wires (red) we want to connect these as well except we want to put a 30 amp inline fuse between them.

This will protect your motor from too much power coming through, if it happens the fuse will break and stop it.

Step 3: Connecting the Drill Battery

Now we have the wires done it’s time to connect everything up. Make sure the fuse is in between the red wires.

You can use Velcro on the back of the battery adapter holder to mount it inside the vehicle. It is recommended that you also install an electrical speed controller kit that way you can control the amount of power going to the wheels and the child can ease into the newly found power.

I know from personal experience they can really fly once you set up the 18v battery.

Step 4: Test the Power Wheels

Once the battery is connected you want to test out them and the motors by pressing down on the gas pedal and watching the rear wheels spin. You will notice a huge difference over the stock batteries right away.

The lithium tool battery pack is also a lot lighter increasing the speed of the ride even more than the 12v or 6v battery you started with.

Step 5: Finish Up

If all goes well the test will have been successful and it works great. Next, go over the wires and make sure they are secure it is recommended to solder the wires together if you are skilled in that area.

You can use a multi-meter to check the voltage.

Close everything up and don’t forget to clean up and put everything back away or you will be like me and never be able to find what I need.

Can I Add Two Battery Packs?

Yes, you can add two batteries instead of one. This will increase the amount of run time for the Power Wheels, basically doubling it.

If you have 20v 1.5Ah you are looking at 15 minutes for one battery and 30 minutes for two batteries. It has been reported that this will also give it even more speed but you have to make sure you do this correctly.

You will want to run the batteries in parallel. If you don’t you will be providing the motors with 36v-40v of power.

While this sounds nice not only will you rip up the lawn but you will push the electric parts of the Power Wheels too far. Not only your motors but your gearbox is made of plastic parts when stock, it will simply rip this apart.

That is why you should run the batteries in parallel, we have a guide on how to do it but here is a simple photo to give you an idea of what we mean but instead of 6V batteries, it would be 18V batteries.

Benefits of Power Wheels Drill Battery Conversion

  • DIY install of the battery is not too difficult and you don’t need to be an expert, however; you do need to have a general knowledge of electrical work and use the fuse.
  • The battery weight is a lot less, making the car even lighter as the stock battery is usually around 10 pounds these will just be ounces.
  • Lithium batteries charge much faster, you can have extra batteries and when using one put another on the charger.
  • The vehicle will have so much power it can even do power slides when stopping (skidding out).

Disadvantages of Power Wheels Drill Battery Conversion

  • Adding more powerful batteries will work the motor more and it can burn out. Recommended to upgrade the motor.
  • Not only the motor but the gearbox can get grinded down if you don’t upgrade the gearbox.
  • The wheels may spin if you don’t add traction simply because of all the power.
  • With the boost of power and speed, it’s time to get out the helmet for the kids.
  • If you have a low Ah battery the run time won’t be as long as the 12V or 6V battery. For example, you can expect 15 minutes of run time with every 1.5Ah. You can combat this by looking for the higher Ah batteries or run batteries in parallel.

Battery Conversion Safety (Important)

Now that the toys have been supercharged it is important to protect the kids. The new charged-up ride can really fly and possibly flip over.

It’s highly recommended at least getting helmets for the children and also higher the lower age limit.

If you did install an ESC then you can adjust the speed for each rider separately but if you didn’t then only allow the older children to ride in a location that is safe and free from hazards.

Power Wheels Battery DIY Tips

  • To stretch out the length of a stock motor and gearbox make sure to not just insert new batteries when the first one dies. Give it some time for the parts to cool off.
  • Upgrade the other parts like the motors and gearboxes or they will fail.
  • Adding a distribution block is a great way to keep the wires organized.
  • This article talks about using the adapter that works with DeWalt and Hercules batteries. You can however make them with other brands like Ryobi and Milwaukee but would need a different adapter.
  • Some people use flashlights and DIY the wires into the flashlight itself instead of purchasing an adapter, this will save money on the overall price as the flashlight is the holder itself.

Power Wheels Battery Alternatives

There are lots of battery alternatives like taking a lawnmower battery and putting it into your Power Wheels. This is a fun DIY project but it is not as good as doing a drill battery conversion.

What is a drill battery conversion? It’s just that!

It’s taking a battery from an old drill or flashlight and making it power your ride-on vehicle.

This can be one of the best conversions if you have some broken power tools that no longer work but you still have the batteries and charger.

The above shows you how to transform a lithium-ion 18 volts battery pack into an upgraded 18v battery. This saves a lot of money compared to just purchasing an 18v or 24v Power Wheels.

Conclusion

There you have it! You saved money on the 18v batteries and the kids get really fast Power Wheels.

This is such a great DIY project to do on stock Power Wheels, however; make sure you are aware this will wear down your motors and gearboxes much faster. If you don’t have an ESC kit you won’t be able to control the voltage going to the wheels so the vehicle will always be moving fast.
