<DIV><FONT face=Arial size=2>I am running dual 1500 mil 6v NiMh packs in
my Ultimate. I am using 2 of the 6v regulated Miracle switches by MPI. I
find that one pack is consistently lower after two or three flights.
Could it be that the regulators are not matched and one draws more then the
other one? Could be a bad battery I'll have to remove and test. They seem to
use about the same amount of mil amps but one is lower in voltage then the
other. I use a 1amp load when testing after each flight and stop flying
when the voltage drops to 5.8v loaded.</FONT></DIV>

<DIV><FONT face=Arial size=2>Keith:</FONT></DIV>
<DIV><FONT face=Arial size=2>That setup works well. I refer to it as a
hot standby, with details covered in a tech tip on the Tech-Aero
website. I prefer a different approach, where you just split the
battery capacity equally between two packs, each with its own regulator. The
regulators must be precisely matched in output voltage setting to allow then
to both actively share the load simultaneously. You can make a very
light setup with this and there are several advantages to it. First, you can
check every flight to see that each battery is being used as expected, which
is very important to know. Second, you double your peak load capacity under
load. A single 5A regulator such as the JAICCIO or the Tech-Aero can
handle the load in a pattern airplane just fine, but it's also good to know
that you can have two 5A regulators online at once, providing a 10A peak
current capability.</FONT></DIV>

<DIV><FONT face=Arial size=2>What I've done is have two batteries and two
regulators, one regulator at 5.7 volts and one at 5.3 volts (or any
voltage lower). On the higher voltage regulator I connect my primary
battery, say a 2000 mah five cell or Lithium. On the lower voltage
regulator I connect the smallest battery I can buy, say a
750 Lipo that weighs less than an ounce. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Since the larger battery is hooked
to a regulator that outputs a higher voltage all drain comes from the
primary battery and nothing is sucked from the smaller battery unless the
main battery drops below 5.3 volts (or fails). </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This works great and when recharging the
smaller battery seldom needs any recharge at all.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I spoke to Jim Oddino before doing this and
confirmed that the lower voltage battery would not suck voltage from the
larger battery since it was going through his regulator (Jaccio
regulator).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This setup has worked great for me and even

<DIV>Correct, I still use separate regulators for each
battery. This system is smart that isolates the bad battery if
something goes wrong. In this way, the bad battery won't
drain the good one. The LED in the receiver tells you if the
battery has been isolated. </DIV>

pack had broken the 3/8 bals a stic ks on impact that were bonded
into place (my battery packs are not "removeable" per say) and the
battey pack was on the ground at the nose of the plane. The plane
was standing vertical on the undamage spinner being held up by
the tree branches. Once we got home we hooked eveything up and
of course it all worked fine. Knowing that the battery pack
essentially had the same charge as when the plane went in, Lance
took the battery pack home for diagnostics. Using the Robbe
charger he cycled the1450 mah &nbs p;pack down....it read 80
mah. He then charged it and it read 1000 mah. Anthony described a
NiMH "brown out" and that is starting to make alot of sense. 6
volt packNiMH , drained does not just die like a 4.8 volt NiCad.
Also an important note is I now think the plane was going in and out
of PCM lock. When I tested PCM lock the throttle did cut, but not to
low idle. It cut to about 20% throttle (programming error), hence
the pulsing of the throttle that I exper ienced. If this diagnosis
is correct then it is a testament to using PCM as I was able to fly
the plane for 45 seconds before impact...had I been closer when the
problem started I may have even been able to score a "10" FAI
