Ok first off the forward current I measure to the stepper motors is usually under 1v. BUT ANYWAYS, If it help you understand MOST control boards support 12 or 24v input. And most printers run nema17 stepper motors. In truth even the heater cartridges and heat beds that are optimized for 12 or 24v can be run in either scenario as they are controlled by a pwm circuit that lets you tune it in the form of ki, kp, and kd settings in marlin firmware. The reason you want the volcano hotend is because it stands the heater cartridge up on its side and gives more heated surface area to the incoming filament. See at high speeds the incoming filament wants to cool the nozzle faster than the heater cartridge can heat it and if you look at the volcano hotend it is easy to see this is what it is trying to correct for. And if you are buying many components to make up an extruder than technically you are still building it, right?
