Started with a ME0201013101 PMSM brushless motor at 36V with a Sevcon controller.
Not powerful enough....

Upgraded to Kelly KBL series controller with 350A peak current (150 continuous A rating) with a 48V battery pack and lost top speed relative to the Sevcon at 36V.

Finally I gave up on the brushless motor and I am going brushed DC with 500A peak. :-)
