<DIV>My experiences with the TP5300s and TP1010C pretty much echo Rex's
below. My 2 TP5300 Prolites have over 160 and 180 cycles
respectively. And like Rex mentioned, they are starting to get a little
'tired' but I still have plenty of capacity for a P07 sequence with an 11 pound
plane.</DIV>
<DIV> </DIV>
<DIV>I like the functionality of the TP1010C and the safety features when used
in conjunction with the TP210V balancer. The combination provides
protection against overcharging an individual cell, etc. I have had no
problems with wrong cell counts, under-voltage issues, etc. However, I
don't charge using a 12V battery as the source. I use AC at our flying
field, or a generator when at a field without the AC luxury.</DIV>
<DIV> </DIV>
<DIV>I would like to also add, no matter what charger/balancer combination you
use, make sure it has an <U><STRONG>active</STRONG></U> safety feature to
terminate charging in case of any over voltage issues!!!</DIV>
<DIV> </DIV>
<DIV>Having said all that, I will add I am disappointed in the accuracy of the
TP210V balancers. I find them to be inaccurate in their individual cell
voltage reporting and associated balancing activities. If the TP210V reads
the cells inaccurately, it will also balance inaccurately. I tested the
cell voltages with a calibrated Fluke DVM and both my TP210Vs read 2 cells
inaccurately (both read 2 cells low) which causes unnecessary balancing to occur
near the end of the charge cycle. While the error is pretty small, the
TP210s try to terminate balancing with all the cells within .005V of each
other so any minor errors reading voltages can lead to significant unnecessary
balancing activity. This causes the TP210V to get extremely hot near the
end of a charge/balance cycle. I usually pull the packs off charge/balance
as soon as the TP1010C finishes the charge cycle. I find the cells are
very close to balance even tho the TP210V is still trying to balance.
However, I will not charge without the balancers due to the protection they
provide.</DIV>
<DIV> </DIV>
<DIV>I have also tried the Hyperion LBA6 balancers and they have the same issue
of reading cells inaccurately as does the LBA10 I tested. Until someone
figures out how to build a balancer that measures cells accurately, we will be
faced with this issue.</DIV>

<DIV>I've got two 1010's and two 210C setups.... I've been using 5 cell
TP 5300 Prolites (5s,4p), wired in series to 10 packs... I have
three</DIV>
<DIV>sets and have used them for two seasons of comps. They have
around 150 cycles on them. I finally puffed one cell on one</DIV>
<DIV>pack this weekend. That battery had been damaged by flying it in a
discharged state... My screw up, I picked up the wrong </DIV>
<DIV>battery and put it in the plane and flew it for a couple minutes before I
figured out what was wrong... When I charged it, it took</DIV>
<DIV>a little over 5300 mAh... Go figure!!!!!</DIV>
<DIV>The 1010 is a marvelous set up. Very safe and easy to use. As
far as capacity, you can read each cell votage during charge right</DIV>
<DIV>on the charger display. I only cycle the battery by flying
them. As the batteries are wired in 10 cell packs, I charge them as a
</DIV>
<DIV>10 cell pack at 5 amps, using the full charge mode.</DIV>
<DIV>I haven't had any problems that weren't solved with the firmware updates
from TP. Mostly individual cell overvolt stoppages from the
balancer.</DIV>
<DIV>As far as loss in capacity, I haven't really kept track of it. I
know that my packs are starting to wear down, but with as many </DIV>
<DIV>flights as they have and how they have been tortured, it's no
surprize My guess is that I have lost around 10%, just judging by</DIV>
<DIV>charge inputs. My cell voltages are starting to vary more and
more. </DIV>

<DIV><BR></DIV>Hi, All,<BR><BR>For those flying E-Power on anything larger
than 40 size planes (mostly will<BR>be using 3000mAh or larger
pack).<BR><BR>I need some feedbacks on Thunder Power 1010C charger and large
capacity<BR>ProLite & Extreme packs<BR><BR>Did you have any problem(s)
with 1010C? If so, I would like to know what<BR>kind?<BR><BR>On the
packs above 3000mAh,<BR>How do you charge the packs, Full 100%, 95%?<BR>Do
you cycle the pack regularly for capacity measurements? Any lose
in<BR>capacity? How many cycles?<BR><BR>I am trying to talk to TP
regarding the charger & packs based on feedbacks<BR>that I
get.<BR><BR>Thank you,<BR><BR>Ihncheol
