Does anyone know these kits? It looks just like a ToSeven DM02. Does that mean I can use a 48V battery and get 500W?

Maybe, probably not. Components with higher voltage handling cost more money. Manufacturers will install the cheapest components that will do the job. Sometimes, you have some head room. The only way to find out is to buy the motor, open it up and read the ratings off of the chips inside. And then cross your fingers and try it out.

No, that’s not how it works, if you want to use a 48v battery you will need a motor with a 48v controller. It won’t work with a 36v motor.

Right... But what if I put a 500w 48V controller for the ToSeven, will it fry the motor?

if you don't have the motor yet and only just looking to buy one, just get the model that you need.
Increasing voltage on a motor that's designed for a certain voltage will fuck up the pedal cadence, since different motors have different kv rating as well as increase the heat.

I don’t know on that specific motor, sorry. But you can swap controllers on Bafang motors so it may be possible. Easier to just get a 48v motor in the first place, by the time you’ve got a new controller that’s probably the cost difference in the first place, plus I don’t know how hard they are to change on the ToSeven motor.

you dont even have to swap the controller on bafangs. just solder on a tvs or zenner diode to the power line going to the screen, and you can run up to 63v on the 36v controller. there are a couple of posts about it on endless sphere and that's what i myself have done recently.
