The nominal voltage of a battery at 3.7V generally means the voltage when it is fully charged is 4.2V or higher.On the other hand, I have several engines that have been running OK for a while now on 3 x AAA batteries, nominally 4.5 VDC, in place of the standard C cell.

I suspect a standard Tomy motor is much the same as these, for example?
