    Hi Rossiter,
    DG is quite correct with his first statement.
    The ESC and motor don't care where the electrons come from, as long as they get some.

    True a fully charged 2S LiPo can measure around 8.4V OFF LOAD.
    But as soon as you put it on load, especially high current as the ESC is rated for the cell voltages will quickly drop to the nominal 3.7V, =7.4V for a2S. That is perfectly normal.

    The snag here is that your ESC has a Low Power Cutoff built in.
    Since it is designed for NiCads and NiMh of nominal 1.2V per cell it will assume that your fully charged 2S Lipo is a 7 cell NiMh, i.e. 8.4V. It don't know nuffink about LiPosπŸ€”
    The lowest safe discharge voltage of an NiMh cell is 1.1V, x7=7.7V
    Therefore I would expect that the ESC would cut off (or slow down perhaps?, not clear from what I can find in the WW-swamp) as soon as your LiPo drops below 7.7V when in fact the battery is still almost fully charged.
    I don't think that situation will bring you much 'Deep joy!'☹️
    If I were you I would use a decent Hi-Power NiMh of suitable volts and capacity for the motor(s) you are driving.
    Cheers, Doug 😎

    Volts are volts. As are amps. So long as you stay within the specified power/volt rating for the ESC, it will work if the power comes from zinc-carbon batteries, Lipos, a lead-acid accumulator or a power supply running off the mains.

    Lipos are max 4.2v per cell, so I guess that ESC has a rating of 12V. 2s would be 8.4v...

    I have been given a new Tornado 50 amp Marine ESC and although it says on it for use with nicad or NIMH batteries, I'm told that it can be used with a 2s lipo. Is this correct, as I prefer to be safe than sorry?
    Thanks in advanceπŸ™„
