ESC ? Lipo cut off?

[SweetZ28]

Hi guy's just want to make sure of something my brushless esc has a cut off setting for lipo LOW-MED-HIGHT now here is the ? i set it to hight now i am thinking this is a higher set voltage cut off example say LOW was 3.0v hight would be 3.4v?

Just want to make sure i got this correct never know with the china esc's!
THANKS
