    2s vs 3s question

    Theoretical Question:

    When i run exactely the same speed, acceleration, with the same gearing in the same terrain (theoretical do really exactely the same) would running on 3s compared to 2s create more heat?

    The amount of heat is caused by resistance. With the same power using a higher voltage, you would need less current and therefore produce less heat. I doubt if you will be able to measure that, but since it's all theoretical...

    Not sure what you mean, but the stk gearing with 3s gets approx as warm as the optional 18t pinion on 2s.

    given a choice I'd go with the 2s geared up.

    Don't spend money to keep stock system cool, use that money to upgrade
