So my basic knowledge of electronics tells me that I should wire the motors as serial to match the controllers. But I see some mention in that thread of that having an impact on the torque of the motor.....so should I really be looking at running in parallel with a resistor? (I guess that ohms law applies here)
Which motors and drivers? And no, ohms law doesnt apply - motors are inductances. Motors can be spec'd as 2.5A/phase "Bipolar parallel" or 2.5A/phase "unipolar" so saying 2.5A/phase without saying how they are wired isn't necessarily meaningful.
