Power Wheels power upgrade enclosure

thingiverse

Enclosure to hold the electronics (voltage disconnect and speed controller) when upgrading the Power Wheels Jeep battery to M18 Milwaukee battery. After the original battery died, I followed the instructions from youtube user "havocware" to upgrade my kids Power Wheels Jeep. I wanted a better way to hold the electronics and hopefully at a minimum make them "splash proof" since my kids enjoy driving through puddles. Its not the greatest design, but it gets the job done. Since its mounted and working, I won't be spending anymore time on it. A couple of notes: I made standoffs to hold the disconnect board in place, and had planned on just using a soldering iron to melt the PLA to hold the board. On my print they weren't quite long enough, so I just melted on some additional and it seems to be holding fine. The standoffs in the published file were lengthened and should be long enough to just melt. When you get the speed controller, make sure it has the removable controls. This way you can run the control knob the the exterior of the enclosure. I also made locating pins for the speed controller. I didn't melt these ones like the disconnect switch. I find once you wire up the speed controller, it naturally stays pretty secure. This way I can also quickly remove it in case of repair/replacement. My original plans for mounting the unit didn't work since I was using the 9.0 amp hour battery, which took up a lot of space in the existing battery compartment. I ended up mounting it in a different location with one screw instead of 2, which seems sufficient. If you do the same as I did, you'll quickly realize the "power out" exit the box at a weird location. It works. Feel free to remix it and move that wire grommet to a more suitable location if it bothers you. 14 gauge wire works great going through the grommets, 12g is tight. If I were to do it again, I would make a hinged or some other type of quick access lid. I've found myself having to change quite a few 30 amp fuses on the speed controller when my kids had it maxed out. I've upped the fuse to 40 amp and haven't had any issues yet.
