I can add an aluminum plate underneath the entire controller board.
Please clarify what kind of grounding you mean.
Casing is earthed, so the heatsink and controller holder also have casing = earth potential - red arrows.
Should the aluminum plate have the "-" potential of the battery or the earth potential?
And there's one more thing that makes me wonder. If the noise signals the controller to reduce the voltage at the output, I should notice it in % SPWM, and according to what the LCD shows, it remains unchanged.
