I want to overvolt my son’s razor e300. I saw the following video where the setup looks really nice as it looks stock, https://youtu.be/YtUTPFb8p-w , does anyone has the wiring diagrams that show how to connect all the wires including the batteries? Can anyone let me know if this setup would make the running time to be short as the batteries are only 5ah? Any suggestions on keeping the stock e300 motor or upgrading to the one mentioned in that video which is a 250w 24 volt? Or would it be better to have a 350w 24 volts one? Thanks !! If there is any other setup that you think it is better but does not require to modify the battery compartment please do let me know. I appreciate all your help!!
