    Anyone got a list of what the battery voltage should be at like every 10 percent, at hover. 100% mine is like 4.32 before taking off, I think around 50% during hover mine was just getting under 3.7.

    I got a low voltage warning the other day when I was at 60%, battery was going under 3.7v for some reason...

    3.7 is low @ 60%. Make sure the battery is securely seated, and mark the battery so you know if it happens again. Also check the battery monitor section and see if it's a single cell that's deviating, which would indicate a bad battery.

    the biggest difference between cells was .02v... 3.7 3.7 3.7 3.68

    yea I should have marked that battery. I charged them both up to 100% and did not get the voltage warning again... but it would be good to know what voltage a healthy battery is at like every 10% at hover...

    Battery voltage doesn't give you a true indication of how much battery is remaining because it varies with how much of a load (amperage) is being placed on the battery. For example fast forward flight or climbing uses more amperage than hovering so the battery voltage would vary at any given amp hours (battery percent) remaining.

    That's why I asked for voltage at certain percentage in hover...

    FPV Camera app can show battery remaining mAh, each cell voltage, current, temperature (important in winter) and more in custom telemetry.
