In general the higher capacity and C rate batteries will produce a higher average voltage regardless of what motor your running.
Look at ProMatch he probably has the least expensive pro quality battery (6000mah 60C) available today.
RevTech\Trinity is probably the hottest name in RC currently and has outstanding batteries and motors. If you want to go faster drop the Tekin motor and get a D3 or Revtech.
