Hi, when you start off a post make sure you put a detailed description in.
Plus, when you say 'esc's', do you mean etc?
Is this an extension of another post? If so, it's maybe a good idea to put this on the end of that one, if you know what I mean.

I don;t think a lot of people know that ESC stands for a speed controller.
Like, just try and keep off abbreviations wherever possible please

so as Hal9000 says,
you haven't provided enough information to answer the question.
how many Amps does your "12-18 volt motor" draw?
you are looking for it's "stall current". if you cant find this info online then try measuring it's current draw with a multimeter with it connected to a battery as you try to to stop the motor rotating.
you will need a motor controller that can handle that may Amps at the voltage used.
note that the first 3 motor controllers on the link you posted are only rated up to 9.6Volts so won't really be much good with your motors.
