I started in RC in 1982 with a 12i and we would run the 1200 mah nicads for 8 minutes. The trick was to gear it just high enough that for the last lap you were running slower but not dead.
And back to the OP, it looks like the mini B battery is a 2S 650 mah. That will work perfectly fine. The motor runs unloaded, it doesn't pull hardly any amps.
