You are going to need more than 5000 mah 25c batteries if a 1.5 turn hv motor is going to be any use at all. I would recommend at least two of those in parallel. My hv 4.5 already taxed my maxamps 5000 mah batteries and a I imagine a 1.5 turn would have the capability of drawing three or four times as much current even with only 2s, compared to a 4.5 turn on 4s.
