plan is to build an electric mountainboard from parts I already have from an old project. I already have an old brushed scooter motor 24v 250w which I would overvolt to 36v and the controller is a 4Qd Uni 8 30amps continuous 115max. (I know using this overvolted motor may burn out but it did work well in an old project)
Or I could buy a new bigger 36v 750w brushed scooter motor
I know most of you will say the thing to do with e skateboards is to get a programmable vesc and run brushless motors ect ect but I am not doing that with this project. this is just a fun cheap project I want to just use parts I have got already (or maybe just buy a new cheaper brushed scooter motor). As I know they work well from my old project.
What I want to know is will the 24v 250w motor overvolted to 36v draw more amps from my battery than a new 36v 750w motor using this 4qd Uni8 controller?
Or will having a bigger 750w motor at the correct voltage actually be more efficient/ longer runtime less amps? or could they have similar results?
Anyone have any ideas which might work better?
