Well lets put it this way. You will need about 1200 watts of power to get to the
50 mph mark. If you run 4s with the drain on batts 3.5v per cell =14 volts.
You be drawing about 85 to 86 amps to get 50 mph.
If you go 5s. It will have less amp draw to go 50 mph at 1200 watts.
But even if the cells are still 3.5 volts. The amp draw will only be about
68 amps. For no matter how much gear you put on it. It will still take
a certain amount of wattage to get the speed you want to run.
