I don't think you were following what I was saying. If we go back to ohms law, of course more current will flow with a higher voltage becuase I = V/R. What I was saying though is the current is also dependent on the resistance of the circuit, meaning the circuit has to draw the current from the battery. It's not the battery itself.

You can't arbitrarily increase voltage without current. You can limit the current that is hitting the pcb if you put in a resistor before it, but that is only dissipating some of the increased current.

The analagy to water flow only goes so far. Trying to increase the water output of a little hose by increasing pressure will saturate.

"No, you guys aren't seeing the big picture here. Higher voltages will work at the low 120mA current range. Higher current will work at a lower voltage range. But, you can't increase both at once. " --- This is wrong.

Current from a battery has nothing to do with the 120mAh rating. That is simply the capacity of stored charge in the battery. The only way to get higher current with lower voltages is to decrease the resistance of the circuit. Increasing voltage will increase current unless there is something saturating or a limiting component.

The truck will draw what it needs (though that can be too much at times). From it's inherent resistance, it will pull the corresponding current via I = V/R. The curciut determines the current pulled from the battery.


And yes, i've run at least 7 MT's with 3.6 - 5 volts. None of them have fried and it has nothing to do with the mAh rating of the battery.
