CloudElectric has Kelly controllers that will work for you for under $200. I picked up a 200A/100A 24-36V Kelly for $99 on sale a couple of months ago. I also picked up a brand new 350A 36-48V Curtis controller for $122 on Ebay in April.
I've got a 4hp powerpack motor that turns 17k rpms. I've spun it using a controller, but I can't imagine running it with a direct connection. Even if you can force yours to work without a controller, you'll want one eventually, so for personal safety as well as the safety of your motor, batteries and vehicle you might as well bite the bullet now.
Take care,
John
