[NSRCA-discussion] TP 1010C & Extreme pack(s) feedback needed

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.
 
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.
 
I would like to also add, no matter what charger/balancer combination you  
use, make sure it has an active safety feature to  terminate charging in case of 
any over voltage issues!!!
 
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.
 
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.

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
sets and have used them for two seasons of comps.   They have  around 150 
cycles on them.  I finally puffed one cell on one
pack this weekend.  That battery had been damaged by flying it in a  
discharged state... My screw up, I picked up the wrong 
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
a little over 5300 mAh...  Go figure!!!!!
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
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  
10 cell pack at 5 amps, using the full charge mode.
I haven't had any problems that weren't solved with the firmware updates  
from TP.  Mostly individual cell overvolt stoppages from the  balancer.
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 
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
charge inputs.  My cell voltages are starting to vary more and  more.

Hi, All,

For those flying E-Power on anything larger  than 40 size planes (mostly will
be using 3000mAh or larger  pack).

I need some feedbacks on Thunder Power 1010C charger and large  capacity
ProLite & Extreme packs

Did you have any problem(s)  with 1010C?  If so, I would like to know what
kind?

On the  packs above 3000mAh,
How do you charge the packs, Full 100%, 95%?
Do  you cycle the pack regularly for capacity measurements?  Any lose  in
capacity?  How many cycles?

I am trying to talk to TP  regarding the charger & packs based on feedbacks
that I  get.

Thank you,

Ihncheol  Park
