MM LiPo LVC on 4S does it work?

[tom255]

I tried to find some threads but damn! so many threads with MM didnt find it.
I just bought Mamba Max and plan to power my 9XL feigao on 4S hope it arms. I read thread "Making ESC better" and found where Arthur told that it arms on 4S with "Auto lipo Cut off" option, but question is does it realy protects 4S lipo? Can anybody confirm that LiPo cutoff actualy works on 4S (12V)
