The stock gearbox and stock motors aren't going to handle even 24V for very long (the little 550 motors will overheat). You could go to 36V only with the correct motor (think "Scooter" motor, or a major gearbox customization ala the quad-damage mode) and a variable-speed controller.
The stock motors are going to last 'awhile' at 18V, but anything more than that and you're going to reduce the longevity a lot. I killed one in < 45minutes running 20.5V max (on a speed controller) -- overheated the motor and the 1st gear (which spun the 1st gear shaft in the gearbox case, ruining the case as well). You can do a 775 conversion for fairly cheap that may survive 24V for a longer period.
What exactly do you want as an end goal? More torque, more top speed?

for more details!)
