What would what be? Please be specific and I will try to answer the best I can.

My example above is general and non-specific (other than my TC3, and I can give details if you want). I was simply saying that if you stay within the recommended operating range of the motors I mentioned you wouldn't go above 60 amps.

When you increase voltage, if the load on the motor stays the same (gearing, tires, etc.) the amperage will increase. However, if this causes the amperage to go above the safe operating range of the motor then you are going to have to change something to reduce the load.

For example, in my TC3 I am running a stock spur (I don't know the tooth count off hand) a 22 tooth pinion and tires that honestly don't get the best traction (so they spin rather easily). If I used a 3S Li-Po, and kept everything the same (meaning the load on the motor stayed the same) the amperage draw would go up considerably. However, this may cause me to exceed the maximum wattage rating of the motor. If I geared down to reduce the load on the motor and was able to keep my wattage at 280 (the maximum rating of the motor) I would be drawing 25 amps (280 watts at 11.1 volts is 25 amps). Again, I'm not saying it would draw this much, I'm saying that assuming I could change the load to get a draw of 280 watts at 11.1 volts, that would be 25 amps. There is a chance I wouldn't be able to stay within my rated wattage at 11.1 volts.
