FEATURES
HARDWARE
zA strong moulded 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 built-in 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 sign lights 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 memory positions are reserved
for your packs.
zApplications for multiple battery types: Li-Po, Li-Ion, Li-FePO4
(A123), Ni-Cd, Ni-MH, 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
heavyily overcharged.
zFor NiCd and Ni-MH batteries, precise static △V(delta V) detection
guarantees a full charge.
zImportant historical data is recorded on nonvolatile memory. The
charge time and capacity delivered last time can be reviewed easily.

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 batteriy 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 temperature
detection sensor when charging.

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 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.

For lithium batteries, at STG, the batteries will be charged or discharged to
3.8V. 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 charged 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).
70Watts @ 12VDC. Max discharge power is limited to 30Watts.

WELCOME SCREEN
As soon as N61e powers on properly, the
welcome screen will appear on the LCD briefly.
It shows the manufacturer logo ‘DUALSKY’ and
the device name ‘N61e’, as well as the software
version ‘V ×.×’.
At this time the cooling fan will run for a short time and both signal lights
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 memory. At the initial use,
it will go to the Top Menu by default.
MENU STRUCTURE
The menu is constructed of two stages/layers, Top Menu and Sub-menu.
