I would not use any charger that does not have integrated balancing.
The TP 1010 or the RC Accessory line of chargers both have the
capability. Like Vince says, it is much safer especially as you get
into larger packs.<br>

<div>Hi Lance,</div>
<div> </div>
<div>I am not expert in this stuff. However, I believe that it is a
lot safer to use a balancer when charging Li-Po. The charger should be
tracking the cells voltage during the charging process, and shut down
the charger if there is something out of order. I agree that the
chances to have problems with 2S batteries is lower than batteries with
more cells that are use for high current draw applications. However,
why not having this feature when it is available and it is safer. I
know that TP-1010 you can read the voltage cells any moment during
charging discharging and at rest. I consider this very important for
Li-Po.</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> </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">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>

[NSRCA-discussion] Li-Po and Regulators for 4C applications</div>
<div><br>
</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>
