how much can a car put out?
 

so far after reading these forums i have been hearing there are "limits" to the cars. for example when modding a bit can only put out 275 ma. whats that supposed to mean? the voltage? so if you layman tri celled and twin motored a car and in this case you wanted to add MOSFETS to ur car would that mean the MOSFETS wouldnt add much?? damnit this is confusing me. and if u reply plz on the bottom or ur reply put it in simpler terms lol.

mah i think the pcb can take more than 275 mah but as far as i know pcb can only take like 5v before its fried

I don't even know how you'd go about adding FET's to a bit PCB. I hear alot of people "talking" about doing that, but no one delivers.

I wouldn't give that another thought.

actually, some guy did it and posted it on a german/english site. i think the mosfets are used cuz it has a lower voltage drop and can give more current, thus maximizing speed and torque of the motor

I was under the impression that the guy on that German site just changed the resistors that feed juice to the motor, thus upping the voltage.

Here is a link to the datasheet for the transistors the german site used for dual cell cell cars. I think this other transistor is similar to what's on the PCB. If you look at the "Absute Maximum Ratings" chart, the MOSFET mod can send a lot more power to the motor(s).
