The current that either motor draws will depend on the load put on the motor. For a given load the L motor will pull more current than the XL, because it has a lower torque constant (kt rating). At a given rpm, the L motor will need require a lower voltage to achieve that rpm than the XL will need.

The point I was initially trying to make (all those posts back) is that at a given speed both motors will give out the same power. The XL will be more torquey, and the L more revvy. The XL might be a tiny bit more efficient, and hence draw less power from the batteries
