[NSRCA-discussion] E-power

[AtwoodDon at aol.com]

One thing I have begun doing is checking pack voltage before I fly,  
verifying full charge condition. 
 
Having multiple battery sets, I may have gotten confused once (I will  deny 
it in public tho) and took off with a partially discharged pack, couldn't  
figure out why I lost power and had to land about half way thru a  flight.......  
Whoops....  If I had actually done that, I guesstimate  I would have put back 
about 5200+ mah into a TP5300, not that I would have  actually done that ever  
 
Good news is, the pack seems fine, has over 70 cycles on it now and still  
going strong (when I charge it)

Thanks  for all the inputs.  The second pac only took 2500 Mah, so may'be the 
 
batteries just need more time to be formed.  I will continue to make  short 
4 - 5 minute flight for the next 6 flights to hopefully form the  cells 
better.  I feel better about it tonight after putting back 2300  and 2500 
respectively, back into each pack :)
