<DIV>There's a charge jack for each battery. One is via the switch and the
other is a separate lead just for that purpose. The only thing to watch
for is that some chargers will not work properly if you charge both at the same
time. Some work fine. The Hobbico Accu-Cycle Elite has definite
issues and should only be used one battery at a time. The problems with
some chargers arise solely because of the common ground when two battery /
switch harnesses are connected together. The common ground can occur
through the receiver power bus whenever two batteries are used and is the only
drawback to a dual battery setup. No matter how you do it, you have to
watch for this condition. </DIV>
<DIV> </DIV>
<DIV>I did some testing that was completely separate from the use of any
regulator or switch harness. On the bench, if you just have a battery on
each port of the Accu-cycle Elite, if you just add a jumper wire between what
they label as the negative battery leads, it has issues as soon as you try
to start the charging of the 2nd battery. If you measure the voltage
between the two while they are charging normally, it typically shows about a 0.4
to 0.5V delta. This would almost certainly cause either an early or late
cutoff of the charging cycle if they were connected together - IF you could ever
get the 2nd battery to start charging. However, during it's battery
detection phase, the charger puts out a large voltage difference between the two
negative battery connections (ordinarily thought of as ground when installed in
the airplane) and it goes into an alarm state. I have heard that other
charger chargers show early cutoffs when tried with dual batteries
simultaneously charging, so the best advice is go one at a time or else unplug
to charge. With LiPo's, we should be unplugging and removing anyway.</DIV>

<DIV>You will get a lighter installation from LiPo's vs LiIon's.
I've heard that the LiIons stand up better to abuse if problems develop made
during charging, but I believe that you are still supposed to observe the
same precautions with either one. Given that, I did switch to TP
LiPo's when I built my Prestige's and they have worked out extremely
well. If you go with LiPo's, you can then afford (weight-wise) to do a
simple, but very effective dual redundant battery setup. I use a pair
od 730 mAh packs and can go all day on that. Check out the Tech-Tip at
<A title=http://www.tech-aero.net/
href="http://www.tech-aero.net/">http://www.tech-aero.net</A> to see how
it's done. It's even easier than pictured in those diagrams now that
there is a dual failsafe switch and regulatior available in one package that
operates off of just one switch.</DIV>
<DIV> </DIV>
<DIV>Let me know if you have any questions, but a pair of LiPo's and a
PLR5-DR is the lightest and most reliable way possible to use LiPo's.</DIV>

<DIV><FONT face=Arial color=#000000 size=2>Dan, I am not planning on
running electric, so I would like to know, do I go Litihium Ion, or
Li-Poly. My guess is Li-Ion because of the make up of the
cell. Not a big fan of Dura-flames, So I am intrerested in something
different. I have heard some good things about your batteries,
and I would like to hear more.</FONT></DIV>
