FEATURES
HARDWARE
zA strong molded custom plastic case.
zStrong heat-sinking capacity comes from a large aluminum radiator
extrusion and its dorsal extension, as well as the fine surface ripple
which increases the heat loss area, improving the reliability of the
charger.
zA built-in highly efficient fan improves cooling internally. The Star
covering continues the DUALSKY unique style.
zSelf-working integrated balancer is available for lithium packs.
Cell’s voltages and balancing state can be checked on the LCD.
zAn input fuse protects your charger and battery.
zTwo status LEDs tell you directly whether the charger’s working at
charge or discharge even from some distance.
zA rotary dial with enter function provides very convenient access to
the menu.
zUp to 10 Amp charge is essential for faster charging speed.
SOFTWARE
zCustomisable options. Ten separate battery profiles are reserved for
your packs.
zApplications for multiple battery types: Li-Po, Li-Ion, Li-FePO4
(A123), NiCd, NiMH, Lead-Acid.
zThe N61e charger provides more convenient and professional preset
charge functions: FAST/ STD/ SLOW/ STG/ CYC/ MANU, options
are available, instead of tedious manual setting.
zTime limits & capacity limits prevent the batteries from being
heavily overcharged.
zFor NiCd and NiMH batteries, precise static -△V(Negative Delta V)
detection guarantees a full charge.
zTen units of recent historical data are recorded on nonvolatile
memory.

PRECAUTIONS
N61e is simple to use, but the safe operation requires some knowledge of
batteries and chargers. Mishandling batteries or chargers can be dangerous,
as it involves a risk of the batteries exploding and catching fire or charger’s
permanent damage. Be sure to read these entire Instructions carefully before
you use N61e for the first time.
zDon’t leave the charger unattended while in use.
zDon’t place the charger or battery on a flammable surface or near a
flammable object while in use.
zDon’t attempt to charge or discharge batteries in incompatible types or
current.
zDon’t overcharge or over discharge batteries as permanent damage
could result.
zDon’t attempt to charge or discharge a battery if it is hot.
zDon’t attempt to balance a battery while the charge output is
connected to another battery.
zDon’t touch the rear aluminium radiator extrusion as the high power
operation can cause it to overheat.
zDon’t allow water, moisture or foreign objects into the charger.
zDon’t block the air intake holes or fan which could cause the charger
to overheat and cause permanent damage.
zDon’t attempt to short-circuit the output as permanent damage could
result.
zDon’t leave the charger connected to a power source or batteries when
not in use.
zKeep out of the reach of children.
zIt is STRONGLY RECOMMENDED to use the themal detection
sensor when charging.

N61e V1.0 or Higher
The N61e provides convenient and professional charging functions, which
are based on different batteries capacity and charging capabilities: FAST/
STD/ SLOW/ STORAGE. Instead of tedious manual setting, the operating
current is fixed at a variant charge rate (C). In the MANU function, you can
adjust the current from -3A to +10 A. The Discharge function is available in
the MANU, CYC or STORAGE functions. During operation, the current
can be adjusted except when using Constant Voltage. The detail below refers
to Table.N61e Operating Function Option.

Battery ating
For lithium batteries, at STG, the batteries will be charged or discharged to
3.8V (but 3.3V/S for Li-FePO4). At this point, the pack is approximately
half-full, which state of charge is ideal for long storage periods.
Still for lithium batteries, the FAST function is only recommended to new
chemistry packs which can be to charge up to 2C according to the
manufacturer.
Whatever you set, the actual operating current will be limited to Max power,
which is associated with input voltage and no more than 90Watts (@15VDC
Input). 72Watts@12VDC Input. Max discharge power is limited to 30Watts.
KEY FUNCTION
The ROTATING DIAL and the EXIT BUTTON are multi-purpose controls.

uild ×××’.
At this time the cooling fan will run for a short time and both status LEDs
will flash on and go off. In this case you can check out whether they are
operating properly.
The system will then go to the most recently-used profile.
MENU STRUCTURE
The menu is constructed of two stages/layers, Top Menu and Sub-menu.

N61e V1.0 or Higher
The Top Menu lists eleven profiles, ten for Battery Profiles (Batt.A, B, …J)
and one for SYSTEM PARAMETER. Except for empty profiles which are
indicated by an asterisk, Every Battery Profiles show its major information
in-line on the LCD, including the number, battery type and quantity of cells
in series, capacity.
The Sub-menu includes three branches, to access Battery Profiles, create
