18V Drill Battery BLEW UP THEIR POWER WHEELS!

- Converting a Power Wheels ride-on toy to run on an 18volt lithium ion drill battery SHOULD be an easy DIY project that you can knock out in just a few minutes. But in our case it turned out to be much more difficult with (somewhat) catastrophic results. We show you how it should be done and something that you might run in to if you tackle this project yourself. Watch until the end and see if you can offer some advice - I’d love to hear it!

Our kids love their Power Wheels truck but let’s be honest for a second: those batteries are absolute garbage. They take forever to charge and if you ever leave them on the charger too long just go ahead and throw them in the trash (please do not throw lead acid batteries in the trash). The good news is that there’s a solution. Since many of us DIYers have a stack of 18V drill batteries we can delete the battery on the Power Wheels and wire in an adapter that accepts drill batteries, which have longer run-times, better chargers, and you can swap them in and out quickly so the kids can play much longer.
You can even do this conversion on an old machine, like we did with this Barbie Jeep that hasn’t run in no telling how long and didn’t even have a battery!
The process is very simple. Identify the positive and negative leads coming from the battery, wire in the new adapter positive-to-positive and negative-to-negative, and let ‘er rip. We added a 30A inline fuse to protect the motors. As you can tell from the video the kids are super happy.

Converting my truck to run on a drill battery actually turned out to be more complicated that it should have been. After we deleted the battery and wired up the new drill battery adapter the truck only had one gear (hi-forward); lo-forward and reverse didn’t work. I let the kids drive around the yard and before they even made one lap the truck started smoking and it was apparent I fried at least one of the motors. However, after a preliminary lookover I can’t figure out exactly why that happened, especially since the Barbie Jeep was so simple (as was expected). If this is something you think you could help with, drop me a comment below - I’d love to hear your perspective.

The issue is you have two motors. One of them is for the low gear and when you hit it in high gear it runs in both motors hence dividing the voltage between two motors. Running the motors on low gear would be too much power for a 12v 550/555 motor without a PWM.
Hope u got it sorted if your still interested, check both motors work with 12v applied to motors if fire ensues extinguish and purchase 24v motors (assuming 18v are elusive), if motors work consider buying 24v speed controller as the 12v one is probably fried, best to use a 24v drill battery or 2 12v in series ie connect one + to the others - then have 24v across the two batteries, most 24v speed controller shut off when v is under 20v,
my kid runs a 24v 12ah little tikes cozy coupe which gets him about 👍 nice vid thanks for posting.
Thanks for the tips!

My issue is controlling the pedal with the PWM controller. If you flip the switch on the PWM, it will either start turning the wheels forward or reverse. I'm trying to wrap my head around on how to wire the pedal to the PWM so it can work by pressing the pedal down to get this thing to start driving and stopping.
Same problem!
Take the 2 wires from the pedal and interrupt the positive wire from the motor to the battery. The pedal will now be the on switch
@@joshc6080 thank you! I will give that a shot. Now when you say interrupt do you mean wire them both into the positive wire coming out of the positive terminal of the motor output? Thanks again.
@@dashvideos4841 unhook the positive wire. The pedal should have 2 wires, hook one of those wires to the positive and the other wire to the battery power. The pedal is pretty much a on/off switch, when you push the pedal it will make the positive connection
You might try an inrush current limiter. Since the PW is designed around crappy SLA batteries, their discharge rate is lower than LiFePo or Li-ion.
Would you mind sharing a link to something like you’re describing? Thanks!
@@GWPHomestead If you're not circuits savvy (I'm not), probably be easier to just swap to a variable pedal and swap out the motor controller
@@OverlordQ Thank you, I’ll dig into it and see where it leads
did you ever figure out what was wrong ? My sons power wheel jeep only ha reverse. forword isnt working. I upgraded his battery to a Ryobi 18V and he's been riding it with no issues for a month. then all of a sudden yesterday he went to get in it and it doesnt go forward. when he hits the pedal while in forward you can hear a click noise then nothing happens. reverse works fine.
I haven't figured it out yet, but I am hoping to dig into it soon. Hoping I didn't burn the switch up too but time will tell. The little Barbie Jeep is still running strong!

The first things that occur to me, is that there is something wrong with the switch. Maybe, it's damaged or worn, and replacing it might work. It's a very simple system. Look at the wiring, and you can work out what the switch is doing. HOWEVER, knowing that one of the motors might be bad, something else occurs to me. It might NOT be the switch at all. If one of the motors is bad, it might be preventing the circuit from working, when it's wired in a series. (Slow forward & Slow reverse) However, it might work, when it's wired in parallel. It's possible that replacing the motors might solve the problem. By the way, you might want to get motors that match the voltage that you're trying to use. You can get entire gearboxes that have different types of motors - if you would like a plug & play solution.
This is all very helpful! Thank you for sharing.
5:00 so if the powerwheels have a clutch thing it has 2 speed modes 1 slow and 2 fast on 1 only 1 motor spin in 2 both motor spins so if u used this pretty much on speed mode 1 that motor is more used up than the other.
That is helpful, thanks!
probably blew the fuse.
most power wheels toys have a 30 amp fuse in the battery or inline and you can blow that fuse.
it could be cheapening of the parts.
also because you got it used maybe something was wrong to begin with
We had the same problem
I have a buddy who’s an electrician, I think he and I might tackle a better way to do it. Works great on the old machine though! 🤷🏻♂️
To much voltage from the drill battery will fry the motors. Buy a voltage regulator and just don’t put it on max. Eventually you’ll have to replace the motors anyways due to the voltage.
Thank you for sharing!
1'd put a 15-24v to 12v 30amp step down on circuit with these newer cheaper motors
Great idea, thank you!
Did you figure out what was wrong with the truck? Fun project!
From everything I've read and everyone I've talked to I think I put too much power to the electronics. Unfortunately it's been a year now and I still haven't gotten around to replacing the motors and anything else that may or may not have been fried. Next time I'm going to add a voltage regulator (about $15 on Amazon) and maybe downsize the fuse to protect the electronics. When I get around to that (and I really hope I get to it soon) I'll be doing a follow up video. The Jeep is working great though and the kids use it weekly!
I have voltage regulatir I just bought and read that it's over loaded. I burned up a barbie jeep I'm a day with 2 dewalts wired in series, but it was fast!!! I'll update!!
Man I done a 12-20volt lithium adapter today and thsi ole power wheels has sat outside for 20 years but 3 cuts and butt terminals and shit you can’t hold the front end on the ground I clocked my 3 yr old 12mph lmao. Yours seems really slow compared to mine today? But I am blowing 30amp fuses about every ten minutes . I blocked reverse so they can only go forward to maybe save some gears for a bit longer . All in all he was very happy and hell may need a helmet as fast as this sob is running lol
Those jeeps have a 3rd gear for high speed there is a screw in the shifter from the factory you need to remove to access the fast gear found that out on mine recently thing is quick now boy lol
You need a bigger motor bc the battery gives to much power
From what I can tell the newer motors just don’t hold up like the older ones. That little Jeep we fixed up is running great, the kids use it almost every day.
Welp it was a good try 🤣
I award the team partial credit 😅
@@GWPHomestead gotta share the credit 🤣
the gears hv to be metal
Just sad
We will recover
