Hi,
This is a very interesting thread, I have an issue where my torment when connected to my recently purchased 3s lipo will only operate the steering but not the motor.
I have made a mistake in relying on the manual for the ESC which says 3s capable rather than the brushless torment manual which doesn't explicitly say not compatible with 3s but doesn't say it is compatible either. Upshot is that I now have a 3s lipo that I can't use!

The hobby shop I bought it from won't exchange as I have charged it.
I was wondering if a programming card could unlock the esc to allow a 3s lipo its not clear what the card can do but I get the feeling its not that simple.
So my options are:
Buy a 2s lipo and shelve/sell this one
Buy a esc that can cope with 3s (any recommendations?)
Is there any way to regulate the voltage down? I guess any regulator that can cope with the current would be expensive!
Bit annoyed about all this, wish I had found this thread before buying the lipo!
Thanks for the info if somewhat belatedly!
