<DIV>Been there, done that... Most of us have, and won't admit it..
lol</DIV>
<DIV>I finally got two colors of bands to place around the packs... Green
and Red. When I get done charging, I place a Green</DIV>
<DIV>band on the battery. After I fly, I place a Red band around the
pack... I was thinking about how clever I was... Right up</DIV>
<DIV>until I flew a pack the other day that didn't seem to have much
power. It had a Green band on it!!! Green means go, right?</DIV>
<DIV>Some dumby got lazy and didn't follow procedure.... New
Rule!!! "ALWAYS CHECK VOLTAGE BEFORE FLIGHT, NO MATTER WHAT."</DIV>
<DIV>I still use the color bands, but now the voltage gets checked anyway!
With multiple packs, it's easy to get confused which pack is</DIV>
<DIV>which. Especially when you are preheating the packs in cold
weather! I got out of the habit of checking the pack voltage because I'm
using</DIV>
<DIV>the TP1010 charger, which displays voltage... Bad habit, if
you're not taking it off the charger and putting it in the plane.</DIV>
<DIV>Just for you Don, MINE DEFINITELY TOOK MORE THAN 5200+. All I will
say is that the 5300's have more than 5300!</DIV>
<DIV>I'm just wondering which pack you did that to? lmao</DIV>

<DIV>
<DIV>One thing I have begun doing is checking pack voltage before I fly,
verifying full charge condition. </DIV>
<DIV> </DIV>
<DIV>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 <IMG

<DIV> </DIV>
<DIV>Good news is, the pack seems fine, has over 70 cycles on it now and still
going strong (when I charge it)</DIV>

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