Thank you for your video....very helpful. Have you assessed the need for either a low voltage shut off to protect your lithium batteries or a brake reduction module that would soften the stop when letting off the accelerator?
No we haven't had to use the brake resistor on either of ours. The low voltage shutoff could be very important but we have the kids trained to stop and ask for another battery as soon as it starts slowing down, so we haven't had any battery issues!
I made the changes but the racer runs slower than it did with the 12v parts. 20v battery fully charged. Any idea why this may be the case? Any suggestion is appreciated - awesome video
Yes we explained that a little bit in the video but probably not in enough detail. The newer motors are rated for 24v and will run about the same as stock motors and gearboxes with 24v supplied to them. In another video we 3d printed a Black and Decker 40v battery adapter and put it in the upgraded dune racer and it runs really fast now! The parts should be linked in the Black and Decker video description.
Does this dune racer not have the limiter screw then let's go fast??? The old Batman version definitely did, I finally figured it out after a year of use! 🤣
Just pop the Dewalt battery out and put it on the Dewalt battery charger. If you have multiple batteries you can stick in a fully charged one to continue riding!
@@wackyengineering yeah it was too late by the time I figured that out, not we are onto bigger and better. Gonna beef up a razor put bike for him to ride around now.

I've got to look into getting my kids one of these!!!!!!!
The kids love them!!
Boy was the 12v Motor on the 20v much faster but they did burn 🔥 up so I went for the 24v motor. Great info.
Awesome, and Thank you!

How much does it cost in total to upgrade it and make it faster? Thanks!
It was about $90 for the gearboxes, and battery!
What gear box’s did you use and motors?
We bought them off of amazon. Check the video description for the amazon link! Thanks!
When you buy the gearbox do they come as a pair or pay individual?
Will these 24v gearboxes work with a 18v milwaukee battery?
Yes they will work but they might be slightly slower because they are 18 volts.

@@wackyengineeringgot it. Thank you!
No problem!
this was excellent, thanks!
Glad you enjoyed it!
what is the off brand lego piece called?
Ticonn lever wire connector
How are these motors and gearboxes holding up?
The motors and gearboxes held up fine until we put the 40v battery on it, then it lasted about 6 hours. One of the motors burned up.
tutorial on installing sound engine boss
Sound engine?
@@wackyengineering yes
24 volt motor and 40watt of power?
24 volt motors, I think each motor is over 100 watt max. In this video we used a 20v battery but we put a 40v battery in a different video later on!
I had the same one. My dad put a v twin mower engine in it
Wow that sounds awesome!
Does this dune racer not have the limiter screw then let's go fast??? The old Batman version definitely did, I finally figured it out after a year of use! 🤣
Wow, we didn't see one but well definitely will have to make sure!
@@wackyengineering there is a screw right below the forward and reverse shifter just take it out.
We did remove that a couple years ago, I forgot! Thanks for checking!
How to charge it
Just pop the Dewalt battery out and put it on the Dewalt battery charger. If you have multiple batteries you can stick in a fully charged one to continue riding!
What is the run time ?;
30 minutes with a 5 Ah battery!
It seemed kind of slow for all your effort. Put a Makita 18 V battery on it and it will come to life.
We made another video with a 40v battery using these gearboxes and motors!
I burnt up a $250 battery doing this, i actually was at work and my wife and kid did and all the tricks in the world wouldnt bring my battery up.
You have to be careful not to run it too low, there are also devices that can protect your battery by shutting them off when the voltage gets too low.
@@wackyengineering yeah it was too late by the time I figured that out, not we are onto bigger and better. Gonna beef up a razor put bike for him to ride around now.
We have a video on the razor with a 20v battery!
all the other videos are boring add more power wheels i got this one for my baby
Thanks for the support!
