<DIV><FONT face=Arial size=2>John,</FONT></DIV>
<DIV><FONT face=Arial size=2>That sounds very good. This may be the
answer. After a short internet search it looks like the astro109, and TP
have chargers in the same price range. Some people swear by their Triton
II. There are a lot of more obscure companies making what seem to be
combination chargers or Li chargers that do what I had requested. your
recommendation carries a lot of weight with me. I'm not sure if balancing
is important with a 2S pack but I do have a passive balancer that can be used
after charging. I think Falcon batteries believes that this is an
acceptable way to balance a pack (doesn't have to be balanced during charging)
so if this is correct the Sirius might be enough. Red Sholefield used to
do excellent reviews of NiCd/NimH chargers but for LiPo's he seems to just
recommend FMA products.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'd love to hear other peoples recommendations but
only for chargers with displays that can show charging information. For
old-school packs I have 2 Robbe Infinity2 chargers and they have a pack
diagnostic mode that is to die for. It finds weaknesses in packs that seem
to be operating OK. Of course it may be a random number generator but I
decided to run the diagnostic a few times a year and if it fails a pack I toss
it. After losing 4 planes to power problems a few years ago I think the
$18 on a new NimH pack is cheap insurance if necessary, but I usually get well
over a year on a pack.</FONT></DIV>

<DIV><FONT face=Arial size=2> The Sirius Lithium charger tells you how
much energy has gone back into the battery as well as showing what the charge
current is and also if it's in constant current or constant voltage mode. That
should be enough for you to figure out if it really charged the battery or
not.</FONT></DIV>

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've been trying a similar setup. 1200maH 2S
lipo with a Radio South 5.1v reg in my glow plane. It's been
performing fine so far but my charger is not a fancy one that tells me how
much is put back in after a day flying. I don't fly electric but still
would like to use a charger that is not just a blinky light. These got
me in trouble with NiCds and I learned my lesson there. Sadly, for
this experiment all I have is the Great Planes blinky light charger that I
use for my foamies. Any recommendations?</FONT></DIV>

<DIV>Hi all</DIV>
<DIV> </DIV>
<DIV>Is anyone using the TP Voltage Regulators with Failsafe switch? They
are available here in Canada (unlike most other things) and I would like
to consider upgrading my ancient NiCD technology.</DIV>
<DIV> </DIV>
<DIV>Considering the 1400mAH 2S TP with the TP 5.1V regulator in a 170
powered Integral. I am using an ARA170 mount...if that changes the
assesment.</DIV>
<DIV> </DIV>
<DIV>Any comments? </DIV>
<DIV> </DIV>
<DIV>Any reliability issues I may have missed ?</DIV>
<DIV> </DIV>
<DIV>Colin.</DIV>
