Indeed, I try to do my math to confirm that I will get what I need without popping breakers. In addition, I've seen even a fresh battery drop voltage when you are pulling power to the drive train: doing your calculations at 12 volts may result in a performance problem in the field. Just our experience though, perhaps others differ.
For systems where the voltage variation would have an appreciable effect on performance, we run all math scaled to 10V (just linearly scale down the free speed and stall torque).
