[NSRCA-discussion] Battery going bad?

[Claude Weimer]

What do you have for aileron differential on your Osiris? Sorry I don't have
a battery opinion.

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.
