I was having some issues with top speed in my slash mini and have come to the conclusion that it is either an RPM limiter, or NiMh voltage dropping severely under load. While discussing that, I was told that a 3s will hold more than 11.1 volts.

Is that true? If it is true is it safe?

If I had 2 3s in parallel that put out constant 12.5v it would solve my problem completely.

Thanks in advance.
