I've added links to the products used in the video description.

To add my two cents: 1. I bought 10 12" long trailer wires ($2 on Amazon) and cut them in half to create my own system of proprietary connectors. I ended up converting one of the trailer wires into a polarity reverser. The wire gauge is not great, but the run is only a matter of inches and seems ok. 2. I used a cheaper non-Dewalt adapter ($15 on Amazon) and soldered directly to the 20v out to the tool. All the electronics and included USB charger on the adapter still work. It still adapts 18v tools to 20v batteries. I filed holes where the two halves of it meet for the fuse holder out and back in, and the trailer wire out. The clamping action of the case keeps my kids from tearing apart the solder and butt connections. 3. I ended up buying a pair of 6ah batteries on sale at Home Depot for $129 to run my kids PowerWheels. These are a great size. I couldn't bring myself to burn up my Flexvolts which are way more $$$ per Ah. The kids change batteries when then get down to one light on the battery. My understanding is that a large Ah battery will get you approximately 10% more speed (also slightly better performance in certain tools). 4. If you use up a 5Ah battery in 30 minutes of hard driving, that works out mathematically to an average of 10amps over 0.5 hours. 5. I ended up with drifty cars due to much more power than the wheels can put to the ground. This effect (which the kids love) creates substantial tire wear. 6. The first time we pressed the pedal on our Barbie jeep (polarity reversed !) the kids flipped the jeep rubber side up completely and landed on their heads. The roll bar on the Jeep actually worked.

Great video! One helpful tip for the these ride ons is to get a bicycle tire, cut it so it’s one long strip, then cut it long ways so the sides are trimmed off. You should be left with a long strip of the middle tread. Cut enough so it wraps around each of the rear tires and then use flat head screws to secure the tread to the plastic wheels. Viola! Assume traction and no more wheel slip!

I’m in England, you Americans have such nice garages and streets, and your kid in that car looks so freaking cool too

My son did a similar thing to his sons little car. Went from 6 volt to 12 volt. Made quite a difference.

Thank you, your video was great and you child loves his truck that's the main idea. but all my parts today and did a tire upgrade to rubber.

Beautiful work and drive to kids 🤩😘🤩

im an electrical rookie. from the dewalt usb adapter is that a smaller gauge wire (16gauge) going to a thicker gauge wire (12 gauge)? Won't that make it heat up? im trying to do the same exact thing as youve done. thanks for your help

Just did this a few days ago on my neices power wheel, On amazon the sell a full kit, battery adapter plus a voltage stepdown controller, there is no speed boost due to the new voltage controller is static 12v output. but it made it a VERY easy install process the Dewalt batteries are so much easier to charge and swap out !

U cud use the circute board to install usb conn3ctions on the dash of the power wheel just. Make usb slots for it and secure it some how behind the dash !! Put the circute board the same but with longer wires. And you will be set. Usb connections for your kids. To charge their electronics

I did this to my son's Hummer it was fast but died in less than 10mins need to get a bigger battery with more ah as my drill batteries are only 1.5ah great video

What about overdischarge? Do desalt batteries have cutoffs inside the battery?

Did the conversion on my sons power wheels it was running fine for a few minutes but now it turns on but will not move. Think I might have burned the motors out any suggestions on upgrading?

Best tutorial I’ve see.

My battery keeps over heating I have a 30 fuse on the ground (red) cable. It keeps blowing. How do I prevent this? 12v to 20v DeWalt

I have a 20v/ 6 amp & 7 amp batteries. How long will it last if my kids play non-stop?

WOW!! Just inspired me to tweak my daughterss Vw Bus 6V Princel, i wonder if anyone got any suggestions to go crazy on it ? Thanks in advance

What size fuse do I need

Pop the top off the old Power wheels battery and you can take the plug out easy and best way i have found for connectors. can also use 10 inch bike tires and cut the bead off and put it around the plastic tire and run a few screws the the side wall of the bike tires to keep them in place.

Was really waiting to see that flexvolt installed and the kit going FULL SEND on that thing

This video was awesome, did this to my little boys 57 chevy power wheels. It is amazing, batteries last alot longer, its faster and just a swap when it goes dead.

Parts kit?

Thanks for the video. After upgrade battery conversion, my rear wheels motors are destroyed being plastic. What can I replace it with to make them durable?

thanks I merged the dewalt battery to the car one for even more power running the car battery positive, and merging the dewalt to the negative on the original battery and and using the dewalt lead to the car.. but the dewalt batteries keep getting drained way to fast for some reason! anyone know why? is it because the batteries are diff volts maybe?

Buy from a alarm supply place there 12 volt 7 amp hour about $7.00 a 24 amp hour about $12.00 and so forth. I used them for fire and burglars alarms. I buy them in the stores that sell alarm equipment.

lol your son cracked me up when he popped in 😂😂😂😂😂

Did this to my daughters frozen mustang and would not work. It goes into a limp mode and the circuit board has a flashing red light. If I put the regular power wheel battery it works fine…Anyone have any ideas ?

If you discharge below a certain volt then the battery cant communicate with the charger to charge. What u will need to do is connect positive and negative leads coming from battery and connect to anither battery for about 30 second. Now you can recharge the drained battery and not throw them away.

The wires on the USB charger verses the fuse wire are very different in size. Was this the same with yours? Can they still be spliced together?

I have added 18 v drill battery to my daughter's ride on car. Originally 12 volt battery. But the car keeps shutting down while operating. You need to turn it off and on again to make it work. Where I have gone wrong. I have a 30 amp fuse to it. Tried an automatic circuit breaker as well but issue is still there. Everything works normal when I put it back on 12 v battery setup.

Cool idea. Curious how old your son is and at what age they stop riding the power wheels?

So I've done this to my son's. I used a 20 volt dewalt battery straight to the connection Port where the regular battery goes but when I try to turn the machine on it just flashes and doesn't actually turn on I'm thinking there's a voltage overload protection somewhere??

I got a question the wire that came on the usb adapter is very thin can that wire cannot be used with that thick wire ?

If I upgrade voltage to a power wheel that has features like remote control, radio and lights will I try them?

Before watching these videos i just stuck some wire with spade ends from the dewalt battery connector to the original battery connector tried it on my son's jurassic park quad normally ran on 6v battery 😂 and it was ripping for maybe a minute before I completely seized the little motor I opened the little motor gear box and only the motor seized time to to order him a new motor and the potentiometer with the battery adapter on low setting see what it does lol thanks

NICE I HAVE EXACTLY EVERYTHING U HAVE THE USB CHARGER HOW DO YOU KNOW WHICH IS POSITIVE AND NEGATIVE

Loving it 😍

How did the stock motor and gears hold up to the extra power?

Whats the right wire gauge? Thinking of doing a T splice.

Did the rear wheel motors ever go out after doing this upgrade? any issues?

About to try just got my boy a dino racer

Since you like using crimp connectors like me, I recommend using a drop of DeoxIT (D100L) on every crimp. They'll last forever.

If I don't want a regulater can I just hook up without as long as I have fuse on positive

Hans, great video, dud you have to upgrade the motors to do this? Most motors are 12v can they handle 20v with ease? All the best stay safe 👍

What size gauge wire are you using I wanna set this up for my granddaughter

Ok guys need some help this upgrade has worked great but after a 20mins the battery is either completely dead or the 30 fuse blows. So what have I done wrong or is this common?

Hello can I use 4x12v batteries for my power wheels it’s 24v System just to get more amps?

Nice. My kids have 2. They are slow as mess tho. Is there somewhere I can buy exactly what I need to do this to theirs?

How long does the battery last? Im trying to dod this project for my little bro and wanna find out the most optimal runtime

Could you add a parts list in the description possibly?

So I can’t just buy a 20v adapter and attach it? What would happen if I don’t add that extra fuse thing people say to add

Do you need the additional fuse with the fuse that comes included inside of the controller?

Where did you get the v controller

Anyone do this to Maserati GranCabrio 12v car?

Question: How do you charge it? Can you charge it using normal power wheel charger or do you have to take the batter off to charge it seperately?

So I converted a power wheels 12v to a 20v w a speed control module and fuse..been running fine for a few months..all of a sudden it stopped. I thought it was the power tools battery, until I plugged in he power wheels battery..it ran, then I plugged in a different black and decker battery and it doesn’t run..any suggestions?

What happened if I don’t used the Dc controller and the fuse can still work ?

Will this method work for the remote controlled power wheels cars?

After this long, did the motors burn out while using a 20v?

I just did this and they love it. But rode for about 5 min and I blew my first 30A fuse. Should I just put a new one in and try it again and see... or...?

Trying to find out... How many weeks did this last before the gears broke? No one ever does a follow-up video to these upgrades.

Hi, where did you set the potentiometer? 12v or closer to 20v?

I have a similar setup but worried I burn up the 12v motors. How long did yours last?

On kobalt car rear wheels turn opposite directions why it is brand new

What’s the runtime like with the dewalt 20v 5ah battery.? Vs runtime of the stock battery?

So I did the exact thing. Except a Milwaukee battery. But my fuse keeps blowing. What would be the reason for that?

How long does a full charge last you guys? I did this for my son, and 1 charge is only lasting me 10 mins. Granted, he's going max speed...

I did the milwaukee 18v and fried my battery after if ran down. Now only flashes and will not recharge. How did you prevent that on yours?

Does the voltage controller have a low voltage cutoff or else you can damage your battery

Do you have a wiring diagram?

At what speed is a good speed to not burnt out the motor

i did the same steps but what happened is the motors gets burned after while

What gauge wires you using to connect everything?

Nice mate. FYI, crimp is better for vibration than solder. Solder for housed PCB.

What kind of run time do you get?

How much longer does it run?

What gauge wire is everyone utilizing?

I did the same thing to my kids 12v f150, but it keeps on popping the fuse and wires get hot. Anybody know how to fix this?

I wonder how long it will last at 20v before it start burning things out

How long does the battery ride?

U dont need the usb charger, Amazon sells the proper adapter, called power wheels adapter to dewalt

I was looking if someone used a flexvolt!!

Wow this kid drives better thab me hahaha. Nice project. Just add the list of stuff you used..

I like your idea but you didn't show the flexvolt battery and you didn't show how high you turned up the controller

Time to wrap those plastic wheels in rubber!

What do I need to do if I want to wire two of these dewalt 20volts in a series?

what about 24v truck?

What's the run time of the 20V? Did the 60V work if so what's the run time on the 60V?

My car burns fuse when It acelerates I need help

They make large rubber bands for aerobics and workouts... Put 6 of them on each wheel and really take off!

Wouldn't it have been much easier using a smaller battery and the 18-20 volt adapter that way you still have a built in discharge monitor?

What if you dont use the motor controller? My kids are going to want the full 20v all the time anyway.

How long did the battery last? Run time

How are you preventing the lithium battery from completely discharging?

That’s exactly what I did for my kids except I’m using the Milwaukee 12v and 18v battery and that thing rolls through sand mud tears right through it.

Man! I did the conversion and my fully charged 4 ah dewalt battery gets drained to zero as soon as my son hits the acceleration. What the heck is going on?

"You got 20v" "yee" which equals dodge scat pack 😄

Wow

Omg toddlers arguing about what power wheels is better like adults

I'm burning out batteries. Any idea why?
