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.

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