[NSRCA-discussion] Battery going bad?

[Jim Quinn]

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.
 Jim Quinn

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.
