Default Walkera ESC low Voltage cutoff???

Has anyone with the Walkera speed controller had problems with the low cut off, cutting off at too low a voltage?
I have buffed a pack with an Esoon ESC by taking the cell voltage to low. When I charged that pack i had a Lipo fire[&o]
I'm planning on using one of the Walkera 30 amp ESC but I am gun shy now. I am worried It will not cut out my 3S pack at 9 volts.

Let me know if anyone is having problems with this ESC.

Thanks
Glen

If the specifications for the ESC don't expressly say it can be programmed for 9V cutoff, or if it doesn't expressly say that it has a cutoff for a 3S LiPoly, I would avoid it, personally.

I did a test with one on my 17 turn Double stator Custom CDR and the Walkera speed control fried in two seconds, at start up.
ESC probably not good for low KV motors.
Hooked up a second Walkera speed control and it was ok did not fry. hooked it up to a 1500 3S lipo and ran the battery down while using my meter.
the cutoff did not kick in until it got down to 8.6 volts Piece of garbadge[:'(]

I'll stick with the CC25
