  Cold?  What's that?  Oh yeah, I have dim memory of that sensation.

    Hi Bob,

    Could it be that your battery was just too cold?
    I've had that happen.
    As the season progresses and our batteries get a lot of use, and they, like us, get a little tired from time to titme.

    If that happens again unplug the battery wait a minute or two and plug it in again.
    When I've done that it goes back to one beep.
    I warm it up a little and fly my whole sequence.

    Could be something as simple as a bad connector on the battery. Double check it, clean it and tighten up the tension on it if possible.

    I had something happen Saturday that is new for me . . . .   I was going to put up a flight with my 62" Osiris for a club airshow, I advanced the throttle to take off, the plane accelerated, then the motor quit.  The Castle Controller was emitting two beeps, indicating a low voltage error.  One of the club members had a meter that measures individual cell voltages and everything looked OK.  I used another pack to put up a flight with no issues.


    When I got home I discharged the suspect pack and recharged it.  I flew it yesterday and it seemed to work OK.  I was practicing(!) some maneuvers repeatedly and the pack quit unexpectedly again, but it may have been my fault for not paying attention to the flight time.


    Is this a sign of pending failure?  The pack has maybe 30 cycles on it.  I have had other packs get puffy and weak but this pack is rock solid.   The pack is a Rhino 5S 5000mAH 25C pack.
