Core Enhancement
Technology (C.E.T.)
It is a common belief that a
high voltage zapper can achieve a better number with the new GP3300 cells. The
new GP3300 will actually hurt its performance if the core is over-zapped. Unlike
other common matching process, Fukuyama Racing have researched and designed a
“State of the Arts” cell processing and evaluation system known as “Core
Enhancement Technology”. This technology will bring the new generation of GP3300
cells to the next level of performance. Out-punching all your competitions with
an ultra low Internal Resistance yet, giving you the highest possible voltage
within the cells threshold. This process not only fires a precision voltage
enhancement boost to the core cells, but it also analyze its maximum enhancement
potential allowing it to achieve a higher voltage yet retain a stable life
expectancy. Not only is this the best way to enhance the cells, it is the only
way to maximize the cells to perform cycle after cycle after cycle!
Fukuyama Matching process:
First, the cells are cycled
numerous time to exercise it’s discharge action before it is then moved to our
C.E.T. processing facility where the cells are analyzed and read with our
computer aided system before a precision boost is fired individually into each
cell. Once this process is completed, the cells will rest for a given days
before the second run of matching process is done. This ensures the cells are at
its top stable condition without overworking the cells. Although this process
takes longer and is considered a time consuming process, we stride to make sure
the cells are working at its maximum performance at all time. Our cells are
charged at 6 amps, discharged at 30 amps with a cutoff of .90v per cell and
run-outs set at 5000 seconds on the latest circuit revision TurboMatcher 4/35
from Competition Electronics. This method not only weeds out the bad cells, it
also trains the cells to get use to the higher discharge rate and perform as
expected by experienced racers. Our cells actually get better and better.
Charge:
During your initial charge for
race day, we recommend you equalize the cells on a tray so all cells are at .90
volts before charging begins. We use our Competition Electronics Turbo 35 GFX to
charge but other chargers will work Please make sure your charger is capable of
charging Nimh cell and is set to run linear charge interface. Turbo flex or
FLEX CHARGING is to be turned off or disabled during the charge on Nimh. If you
charger has trickle charge for NiCad, it will also need to be turned off or
disabled. We have been using a
linear 6 amp charge rate with very good results. But a 5 amp charge will give
you a slightly more runtime. For maximum performance, we suggest you to peak
just before your race. If it has been sitting for more than 30 minutes, repeak
with the same setup as the initial charge. If it's been sitting for 5 minutes or
less you can repeak it with a .01( 10 mv ) peak detect.
Peak detect cut-off ( voltage
threshold ):
We suggest a .05 ( 50 mv ) for
6 cell packs.
We suggest a .03 ( 30 mv ) for
4 cell packs.
You cells should
be warm to slightly hot but not burning hot. To determine this, the temperature
should be between 135f to 155F. If the temperature reaches above 155F, it is
suggested that you shut off your charger or turn down your peak detection.
Charged packs should be right before you race while the pack is still warm.
Warning!: Over-charging your cells will damage them or shorten it’s lifespan.
Always charge your cells away from flammables and leave open spaces at to vent
around the pack during charge.
*Important
update!*
Lately, it has been brought to
our attention that another renowned matcher has suggested DEADSHORTING the
packs. While this may seem like a good idea to most but some racers are unaware
of the consequences if done wrong. First, each and every cell has to be brought
down to 0.00 volts. This is not an easy task since as soon as you lift the pack
off the discharging tray, the chemicals inside the cells will react and come
back to life gradually filling back up. This will cause you to short the packs
and ruining the cells internal structure. Second, the voltage gain is very
slight and you risk loosing valuable runtime in the process. Third, fires or
sparks may cause injuries due to shorting out a pack with voltage still in it.
Fukuyama Racing does not suggest you DEADSHORTING the cells to gain that
ever-so-slight increase in voltage and taking a risk that yields no benefit
other than following what other risk takers are doing. USE YOUR OWN JUDGEMENT
AND AT YOUR OWN RISK. WARNING!: FUKUYAMA RACING WILL NOT ASSUME ANY LIABILITIES
NOR TAKE ANY RESPONSIBILITIES FOR DEADSHORTING THE CELLS.
Discharge & Storage:
At the end of the race day,
discharge the pack down to .90 volts per cell. This equals to 5.40 for a 6 cell
pack or 3.60 for a 4 cell pack. Let the pack rest until the next time you plan
on using them. You do not need to place them on the tray. You can store it
without any charge on these newer GP 3300. WARNING!: MAKE SURE YOUR CELLS HAVE
COOLED COMPLETELY BEFORE STORING THEM IN A CASE OR BOX.
Cycling:
We do not suggest cycling your
packs simply because it yield no benefit except making your packs work an extra
cycle. We do however suggest that when cycling, make sure the packs have
adequate time to cool before discharging. A quick cycling method will most
likely hurt your cells because of heat.
