M620 - Difference between 750w and 1000w variant?

[Teflon]

I have the 750w m620 canbus variant.
what’s the difference between 750w and the 1000w? Is it the controller only?

if it’s the controller only can I swap a 1000w canbus controller into the motor? and is it even worth it. I currently peak at 1255watts

thanks

Wondering the same since the m620/30 upcoming can't be reprogrammed? Or is that totally wrong. Bafang Ultra M620 Programming aka Taming the Beast

I want to use either the Luna 750w stamped BBSHD reflashed , or the m620 for a bulk bike build project with stamped 750w and more powerful controller

That one is uart, which is easily programmable. The ones manufactured after 2020 (or something around there), are canbus..canbus is a proprietary protocol the furthest people got with it is changing speed limit, tire size, and ability to flash different firmware..
the m620 controller is integrated in the motor, you want specifically a uart m620..
but I already have a built bike I just wanna know the difference between the 750 and 1000w variant
