<DIV><FONT face=Arial size=2>Falcon Batteries are located in Houston, have
been supplying batteries to the sport guys for several years, and enjoy a
reputation for having a good product with good service.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Last fall they expressed interest in the
pattern market but were unsure of the requirements. I had just entered the
E-power arena for pattern and had a Partner (Hacker C50-14) fitted with
equipment capable of recording relevant parameters in flight. Falcon loaned
me 5S2P -5000 mAh packs which I flew and compared performance with that
of well known "pattern" packs. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I insisted that pack life was equal
to flight performance in importance. Falcon responded by creating the F3A
Pro Series packs described in their ad in the K-Factor. Their philosophy is
that precise cell matching in packs using the absolute best cells with
respect to voltage / capacity / impedance will result in exceptional pack
life. They chose to use a 5S2P configuration to limit cell count for
reliability. They also selected the relatively new "High Voltage
Retention" cells to meet my requirement of maximum voltage at the current
flow observed in pattern. As you've noted, they back their product with
a 6 month warranty.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've been flying the Falcon F3A Pro packs since
late December. The data I've gathered indicate these cells are, at least,
equal to other packs I've flown in terms of minimum voltage at pattern
current flow throughout F3A P/F flights. Pack heating is
quite low. So far I've 40 flights on one set - mostly P-07, and see no
degradation in flight performance. Cell set balance is exceptional
(balancing connector included). Only time will tell how long these things
will last, but with Falcon's warranty I don't have to worry about a budget
busting experience. I'll let the list know as I reach cycle milestones. The
only negative to these packs is that the weight is 1260 grams which takes
care (I've 2 legal airplanes) to meet 5 Kg. - but certainly a
consideration.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>And yes, I've received some price consideration
for the testing and data evaluation I've performed. </FONT></DIV>

<DIV>Better news is the battery manufacturer that is giving 6 months of
warranty. See the add in the last k-Factor. I think is called Falcon
Batteries. I never seen the brand but the fact that they are giving
6 months warranty is very important. I hope that the competition
start to see this trend and we see warranty going up to a year.</DIV>
<DIV> </DIV>
<DIV>Who is using those batteries? Reports good or bad are
welcome. </DIV>

<BR>> That post is by Charlie Wang, head of Thunder Power. Charlie
has been <BR>> running cycle test experiments where he cycles Thunder
Power Pro Lite <BR>> batteries with 2C and 3C charge rates, and 4C
discharge rates. His <BR>> experiments have convinced him that 3C
charging of Thunder Power Pro <BR>> Lite batteries does not harm the
batteries. <BR>> <BR>> This is a major step for electric R/C.
Consider a situation with one <BR>> charger, two batteries, and 10
minute flights ! - low cost, typical <BR>> pattern and sport
equipment. Charge times are inside of 30 minutes. <BR>> Allowing 5
minutes for pack cool-down, it is possible to log 5 flights <BR>> in
less than 2 hours. In a pattern situation this isn't yet possible,
<BR>> because it takes a 16A charger to charge the 5.3Ah pack at 3C
and they <BR>> don't exist. Using available chargers, two TP 1010's
($320-$400), two <BR>> TP 210 balancers ($140-$200), and four
5s4p5300 packs ($1100-$1300), the <BR>> <BR>> time for 5 flights
would be something like 130minutes. <BR>> <BR>> 3C charging
(currently 2C with pattern packs and available chargers) <BR>> allows
you to fly just as much with fewer batteries. That saves outlay <BR>>
costs, if not cost per flight, and certainly reduces the length of time
<BR>> you are stuck with current technology. <BR>> <BR>> More
good news from the electric world. <BR>> <BR>> Those of you
planning on charging at >1C, make sure you read Charlie's <BR>>
post. He gives specific guidelines! and practices. <BR>> <BR>>
