Hi,
this is the part that I do not understand.
" they will overheat trying to work just as hard with less amps and or volts". Well, I would think, the motor can only get as much power as the battery actually can supply. The battery has too less power, including insufficient power to overheat (the motor is capable for much more than the too small battery supplies).
If I put your argument a little on the edge, and you say "...will overheat with less amps and/or volts..." then it could also be said that the motor will overheat if you put on a AA 1,5v battery (less volt and amps). You will reply "no, no, of course not with such small battery", but basically that is the relation in your answer.
It is this answer that is often seen, but my mind simply doesn't accept it. (no offence, but I'm the type who would like to dig to the full answer when I put an interest to something...)
It could very well be, that the real reason ends up in the same correlation (too less powerpull a battery causes problems) but it must be for other reasons.
The real reason could very well be the voltage ripple as described in another thread.
