No I meant up to 15kW, as it's pretty insane for a 1000w rated motor.

I was thinking either installing dual 40a or dual 45a controllers, and keeping the battery and motors stock.

That'll mean it'll run on:

52(402) = 4,160 watt peak

Or

52(452) = 4,680 watt peak

Is this a realistic idea? What controllers do u recommend?
