The Kostov 11 Alpha wants 240V. So in my opinion the controller makes a pwm signal of it. So the battery system has to provide 250V, is this correct? So its not possible to use an 100V battery pack as an example?
You can certainly drive the Kostov with 100V, but your max RPM will be severely limited. Even if your battery system is rated at 250V, it will sag below 240V under load. Better to target 300V, the controller's pwm will limit to 240V if you instruct it to never exceed this voltage.
