    I always used 3.3/cell on all my heli and MR batts.

    The rule-of-thumb has always been never drop a LiPo cell below 3.0v or risk cell damage.
    3.3v allows some buffer to allow slow return and landing before getting to the damage threshold.
    (Note this is for non-LiHv cells)

    As a matter of comparison... The P2s had a 'hidden' under-load voltage cut-off value of 10.65 (or 3.55v/cell) built into them which could not be accessed or adjusted by the user.

    YMMV

    For some reason I can't upload video as it says network error
    When connected it starts off by saying
    ALL 12.6
    Cell 1= 4.18
    Cell 2= 4.19
    Cell 3= 4.20

    Looks good.

    4.20/cell is a 'full tank' for a standard r/c LiPo.

    Well 3.3v/cell or 10v/pack for a 3S depending on the alarm setting capabilities is what I set the alarm to as a minimum.

    Why not set a bit higher to see how long you flights are and get a feel for it???

    I use to run my zippy 2800 to about 3.5/3.6 know I run the multistar 5200 mah to about 3.1/3.2 volts per cell I think it depends of the battery mah and size is but that's my opion
