The IntelliPeak Twin Pulse Charger is
capable of charging both nickel-cadmium
(NiCd) and nickel-metal hydride (NiMH)
battery chemistries, as identified by this
symbol. Look exclusively for battery chargers with this symbol to
handle both NiCd and NiMH charging needs.
While similar in appearance to sub-C NiCd batteries, NiMH batteries
have a different internal chemistry and require a different charging
method. It is important not to allow NiMH batteries to overheat
while being charged. Heat can adversely affect the performance of
NiMH batteries. If overheating is observed, disconnect the battery
from the charger immediately. Do not deep cycle NiMH batteries.
Permanent damage could result. Store NiMH packs with some
voltage remaining on the cells. Use a NiMH batter y pack no more
than three cycles per day, with a two to three hour break in-between
for cooling. More frequent use is likely to overheat the pack.
To use a 12V DC battery for input power, attach the red alligator clip
to the positive (+) terminal on the battery, and the black alligator clip
to the negative (-) terminal. It's best to use a clean DC power source
whose output is filtered to remove unwanted electrical noise. To
achieve the maximum potential of the Twin charger, the source
battery must be capable of delivering at least 7 amps of current while
maintaining 12V DC.
If using 110V AC for input power, connect the black AC plug to a
regular 110V wall outlet. Do not connect the DC input leads to any
power source simultaneously with AC input, as permanent damage
to your charger may result.
Anytime AC or DC power is applied to the input and no load battery
is present on either output, both LEDs will flash at a slow rate.This is
simply to confirm that supply power is present on the input. It is not
recommended to leave the IntelliPeak Twin connected to any input
power for an indefinite period when loads are not present on the
output.This will unnecessarily shorten the lifespan of the charger.
The IntelliPeak Twin charger incorporates a miniature fan to help
keep all internal components cool during operation. This will help
extend the service life of the charger, as well as allow the charger to
function more efficiently .The fan will turn on anytime a load is present
on the charger's output.
The IntelliPeak Twin Pulse Charger is fuse protected from current
overload. Replace the glass fuse only with one of the same rating
(250V/3A) and size (5x20mm). CAUTION: Disconnect the charger
from the AC power source and the load battery from the charger
before replacing the fuse.
The built-in output leads have standard connectors on the end.This
is for direct connection to common 6 and 7 cell R/C sub-C battery
packs. An adapter cord is included for charging Futaba®transmitter
batteries with the Twin charger.This adapter is designed to connect
directly to Futaba transmitter charge jacks and ONLY the output of
Peak Charger 1 on the LEFT side of the charger.

SPECIAL FEATURES
Congratulations on your purchase of the IntelliPeak Twin Pulse Charger by DuraTrax! A
breed apart from other chargers, it offers the ability to peak charge TWO battery packs at
once.The Twin Pulse Charger is the ultimate in convenience for models which operate from
two batteries simultaneously, or modelers who use multiple packs on a regular basis.
The Twin has TWO independent high-rate peak charge circuits, to
recharge two battery packs, and automatically terminate fast charge
when peak charge is reached. The charge circuits are totally
independent of each other.This means, if desired, only one pack can be
charged at any given time. Or, two batteries can begin fast charge
simultaneously. Or, one battery can begin fast charge, and a second
battery can be connected and charged at any given time. The Twin
delivers pulsed currenton its outputs instead of linear charge currents.
This allows batteries to achieve peak charge without excessive
overheating, while keeping the charger itself cooler to achieve higher
charge efficiency and extended lifetime.
Peak Charger 1: The controls for this charger are on the LEFT side
of the charger.This port is capable of charging 6 cell (7.2V) and 7 cell
(8.4V) sub-C size battery packs at a minimum 3.5 amp rate, or 8 cell
(9.6V) transmitter battery packs at a fixed 1 amp rate.
1.For 6 and 7 cell sub-C packs:
a)Set the CHARGE AMPS switch to the 3.5A position.
b)Connect the 6 cell (7.2V) or 7 cell (8.4V) pack to the output
connector on the left. Peak charge will begin automatically,
indicated by illumination of the red LED.
c)When peak charge has been reached, the Twin will automatically
terminate fast charge and go to 100mA trickle charge, indicated
by the flashing red LED.
d)Six and seven cell sub-C size packs can remain in trickle charge
state for an indefinite period.
2. For 8-cell (9.6V) transmitter packs:NOTE: The Twin is designed to
automatically start peak charge when battery voltage is detected
on the charger's output lead. Some transmitters may have a diode
in their charge circuit which might prevent the Twin from initiating
peak charge. Extra design considerations have been added to
overcome this common problem, and the Twin should still begin the
peak charge process on such a radio.If for some reason, however,
the Twin will not begin peak charge, it might be necessary to
charge the battery directly when removed from the transmitter.Or,
contact your radio manufacturer for possible removal of this diode.
a)Charging 8-cell batteries is best accomplished when using 110V
AC input power, or DC input power of greater than 12V but less
than 15V. If using a 12V automotive battery for input power,
starting the car’s engine will increase the input voltage to
approximately 13.8V.If necessary, starting the engine should allow
the Twin to peak charge an 8-cell transmitter battery completely.
b)Set the CHARGE AMPS switch to the 1A position.
WARNING: Never attempt to charge transmitter batteries at
the 3.5 amp peak charge rate! Failure to obey this warning
will likely result in permanent damage to the Tx and the
battery. Transmitter charging should ONLY be achieved by
using the 1 amp charge rate on the Peak Charger 1 output
on the left side of the charger.
c)For Futaba transmitters, attach the included Futaba transmitter
adapter to the output connector on the left. Adapters for other
radio types can be purchased separately (see list at the end of
this manual).
d)Connect the output of the adapter to the charge jack of the
transmitter. Make sure the radio's power switch is in the OFF
position. Peak charge will begin automatically, indicated by
illumination of the red LED.
e)When peak charge has been reached, the Twin will automatically
terminate fast charge and go to 50mA trickle charge state,
indicated by the flashing red LED. Transmitter batteries can
remain in the trickle charge state indefinitely.
P
eak Charger 2:
1. The LED and output connector for this charge circuit are on the
RIGHT side of the charger.
2. This port is capable of charging 6 cell (7.2V) and 7 cell (8.4V) sub-
C size battery packs at a minimum 3.5 amp rate.
3. Peak charge will begin automatically after the battery is attached
to the output connector on the right, indicated by illumination of
the yellow LED.
4. When peak charge has been reached, the Twin will automatically
terminate fast charge and go to 100mA trickle charge state,
indicated by the flashing yellow LED. Sub-C size 6 and 7 cell
packs can remain in trickle charge state indefinitely.
WARNINGS:Never attempt to charge transmitter batteries on
Peak Charger 2 (right side), as the 3.5A charge rate will
damage the transmitter and its batteries. Never leave the
charger unattended during fast charge. If the battery or
charger become hot at any time, disconnect the battery and
remove input power from the charger immediately! Failure to
do so may cause permanent damage to the charger and
battery,and may cause bodily harm.
