This can only be answered when anyone tries High Voltage. I got 30 minutes from my 25C 3700mAh 4S packs in a 8S set up in my MBX5T. I only got that though because I had to go from a 15T to 17T pinion in order to fit my Neu 1515/2Y, but with the 15T in there I was able to get almost 1hr of run time. So all the math can be done, but to find the true answer, one has to actually go HV to see it happen in front of you.
