Any by far the soft start / stop is the best feature - a must have really.
Drill/lawnmower batteries are small enough, that you can have a similar runtime rating, in a smaller package. You might want to consider having two battery packs in parallel - located in the back. You can get adapters that you can permanently mount to something, so that they are easily swapped out for charging. This allows you to remove the batteries when you're not using the vehicle - to keep the batteries out of extreme heat or extreme cold, during summer or winter. The front is a nice place for the battery, but it might not be as convenient to access as having the battery/batteries in the back.
Some motor controllers have a brake function built in. You would just need to wire the shift lever to the motor controller, so that it also handles the forward and reverse functionality. Then, you could rig an additional pedal for braking - just in case the conditions call for it. It might be a good time to train on the brake/accelerator configuration, that your typical automobile has.
Pretty slick!
Hey Anthony - great video and great project! So I've been looking to do the exact same thing for my son's dune racer that I picked up for $60. He is only 1.5 years old, so it is my winter project. The question I have for you is how you wired everything together? Did you disassemble the shifter and replace it with a DPDT switch ? What do you do with the three wires from the pedal? Also, I want to use my dewalt battery packs so I need to install a low voltage cut-off. Again, great video, i would just love to see some more detail 🙂
Did you have to do any mods at all to get the new pedal to fit with the existing pedal plate?
Hi thanks for posting. I’m trying to replicate your set up on my Escalade. Can you explain how you connected the wiring from the new PWM to the existing 3-pin connector found under the stock pedal?
Hi, Not sure how the escalade is wired, and basing some of this off memory. Because two of the 3 wires (red and orange) went from the front to the shifter box, we used those as a jump point to tie in the front mounted battery. Keep in mind, eliminating that 3rd wire (white) that goes straight to the rear battery compartment is what applies the braking effect when off throttle. So in our setup we lost that braking.
Love ot
Hello, Are those 775's? What battery are you using?
Thank you.
Hey good job! I connected a motor governor on mine that includes both a slow start and slow stop function. I had to connect the PWM after the pedal for the slow start to work, but could not make the slow stop to work, so I lifted (cut) the ground cable on the pedal and to my surprise the slow stop started to work. Not sure to leave it like that or add a recommended resister on that ground connection on the pedal. I thought I'd share this discovery for whatever its worth. I have read that the ground connection on a power wheels pedal is to help short the motor in order to stop it cold. But if the ground connection there is cut, well the governor is now in total control-- I think?! I would have to test this without the governor to see what happens... But I already got everything wired, crimped and wire tied, that I don't want to rewire it to test this theory.... Hopefully someone can test this to see what a default wiring will do if they cut the ground cable on the pedal. Will it work? Will it stop hard or slow?
Hi, thank you! I can’t speak to the removal of the ground wire as I simply used two of those 3 pedal wires to transfer power from our front mounted PWM though the shifter, to the dual motors. Having eliminated the stock pedal I’m not sure how that operates with the 3-wire setup, also why I like the PWM we found as the new gas pedal connects directly. I’m interested to know which PWM / speed controller you went with. My first attempt also used a soft start/stop PWM after the pedal, but before the motors. It worked for one wheel motor, but when trying to connect both motors it didn’t. I believe the unit we tried wasn’t rated for that much power, or possible we wired it incorrectly. We then used the setup in the video.
In our case, after reading the supplied directions again, what I missed on the first go around was that you can configure things as we did in the video, or also add a second pedal which operates as a soft stop brake. That was one area I was not happy as the car coasts further then comfortable if on a hill. Once we try the second pedal, I’ll add a pinned comments with any updates.
Cab you share parts list ? Iam in search of a adjustable soft start module. Any help would be greatly appreciated
Hi, I didn't realize YT was chopping off the links already in the description. Added Tiny URL's and clickable links in pinned comment. Thanks for watching.
@@asim197GT can you provide a little more info on how you wired the 3 pin connector from the original pedal? Looks like you hooked up the M+ and M- terminals from the PWM to two of the pins. I would like to replicate this. On what pins did you land the M+ and M- wires? Where is that white wire going? On my Escalade, the white wire connecting to that terminal is coming from the positive battery terminal…is that the same case here?
@@user-ij4kf7nz6n If I remember correctly, and based on the video, the white goes from the old pedal to the rear battery compartment, which we did not use in our case. Only used the red and orange to connect the motor outputs (+/-) through the front ‘firewall’ battery compartment mounted PWM and those go to the shifter box which will reverse polarity to the motors when using the shifter. To tie the front and rear batteries together new leads were installed. We only just recently added (2) 12v batteries in series, and might have to make an updated video.
