Have you ever bought a toy car for your kids only to be disappointed by its shockingly underwhelming speed? Well, before you banish that toy to the attic or cupboard of no return, first try this genius life hack that won’t only make it much faster and much more fun, but will also do the perfect parent-child bonding project. So let’s see how to turn that toy from slow to GO knowing your voltage limitation.

When it comes to making these toy-cars faster, it’s all about how much juice your car has vs. how much it can handle. Most manufacturers play it safe and underpower these cars because pushing their limits does increase the risks of something going wrong. While we discuss this fun and exciting bonding activity, we caution that this might be damaging to your car if not done carefully. If your toy-car is initially over 6v, there is a chance that this hack might not work because of something called the H-bridge, but that’s a bit more advanced, and we won’t cover it here.  Ready? Then grab a screwdriver to safely open your toy-car (and be able to put it back together again!), and let’s go!

Pro-Tip: get a container for all your screws, and before you start taking out the insides of your toy-car, snap a quick pic with your phone. This helps when putting everything back together, trust me!

Once open, you should be able to see at least these three parts: the batteries, the motor, and the circuit/control board. On your control board, there should be a microcontroller chip (a small black disk). In a perfect world, we would know what the voltage limitations on all the parts are before we introduce a higher voltage. But as this chip is most often the weakest link, we will use it as our safety guard regarding how much juice you can safely push through your toy-car.

On this chip, you should find a serial number that you can use to look up what voltage it can handle. Once we know our voltage limitation, we can start with the Frankenstein experiments of calculating the batteries’ voltages to add more or even bigger batteries like 9v batteries.

Tip: after linking all your batteries to the car, first try it to see if it works before reassembling the whole vehicle. Put your vehicle back together, and if you don’t have space for the extra batteries inside, try using some wires and insulation tape to MacGyver it onto your car. Remember when wiring in more cells to wire them in series or line. That means making sure that you attached the negative pole of your new battery to the positive pole of the old one and vice versa; however, a quick google search will make sure you’ve got it.

That’s it! Your toy-car should be much more fun and exciting now. Have fun teaching your kids about donuts and chuckling at your neighbors’ faces when your kid’s car overtakes theirs.  While you’re thinking about revamping your toy vehicle, take a look at some ride-on toy vehicles that are even more fun right here at Ride On Toys Planet.

Check out this small project using a Duracell 9-volt battery, a hot glue gun, bottle caps, and some ingenuity from WEAREX.
