<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Verdana><span
style='font-size:10.0pt;font-family:Verdana'>Jerry--just a couple
thoughts: I will probably never use a battery for a receiver/flight pack
again that I haven't been in charge of its history. If you've been
paying attention to its characteristics since new, we can generally tell when
they start to lose capacity--and for me, there was a point on the ESV when it
got there, I got a little nervous about going up 'one more time'.
When it would approach that point after about five flights, then I would
figure it was 1. if early in its career--then to cycle and 2. if in to the
second or third year(sometimes longer) it was time to retire it.
Nicads for me have been pretty reliable that way and I've been comfortable
running one pack. You can still go to five cells in nicads for additional
capacity and power with a regulator and still have that reliability. I
think most of the guys that have gone to lipos can enjoy the increased capacity
and power along with an increased discharge rate in a smaller, lighter package.
But I don't get the impression that they trust them like
nicads. Probably the best thing to do is monitor your batteries of
any type with a good, loaded ESV to keep an eye out for any unusual
battery behavior. The two battery debate is a little like the single
versus twin debate in full scale airplanes--some guys think twins just have
double the chances to fail.<br>
All that said, I understand some of the new receivers are a little touchy
regarding low voltage situations. I had an older receiver in an airplane
that I bought used with a 'new' battery--turned out the battery was bad--but
got a warning(hold) and was able to land--but showed NO volts afterward. <br>
Chances are with the newer stuff, it may not have made it back on the
ground in one piece. So using a 5 cell nicad or 2 cell lipo with
regulator may not be a bad idea and monitor with a good loaded ESV.<br>
FWIW<br>

Jerry, I think the short answer is no. But there has been much discussion
regarding dual packs for back-up. An example ot single pack usage is
using a 2 cell lipo at around 780-800ma for practice and 340-380ma for contests
to make weight. These are used with voltage regulators with variing
outputs.<br>
