Motor help!

how fast do you think this motor will take my EV if my ev weighs about 600-800 pounds and how many amp hours would i need my batteries to be to get like at least a 30mile range. the guy who is selling this motor said it needs about 150amp to hit 10hp and said peek hp is over 14. also should i get 8 6v batteries or 4 12V. any help would be appreciated.
