Hi everyone, I am planning on upgrading my kids Razor MX125 with a larger motor, controller and batteries. I ordered some parts off Amazon and the wiring diagram was in chinese. I couldn’t understand the instructions and had to figure out what wires did what. Here is a breakdown of each wire connector so you don’t have to guess. Let me know if you have any questions.
Here is the video of the installation on the Razor MX125

I know that I am pushing the controller to its limits with 40v with my 2 dewalt batteries.
The parts were relatively inexpensive, and I already have 2 lithium ion dewalt batteries on hand from my power tools. I was going to go with a 48v controller, but I didn’t think my 40v dewalt batteries would power a 48v controller.
Let’s see how long this setup lasts?
