Introduction

Special Features

Please read the entire instruction manual completely and attentively
before using. This manual contains a wide range of information on
operation and safety.

Optimized Operating Software

SkyRC e660 features the so-called AUTO function that sets the feeding
current during the charging/discharging process. It can prevent
explosion from overcharging caused by the user, and charging process
will be disconnected automatically once malfunction is detected. Its
entire program s are co ntrolled through two-way linkage and
communication to achieve maximum safety. All the settings are
configurable.

Battery Memory (Data Store/Load)

Up to 10 different charge/discharge profiles can be stored for your
convenience. You can keep the data pertained to the program setting
and call out them at any time without any special procedures for
continuous charging/discharging.

Terminal Voltage Control (TVC)

End voltage is adjustable for professionals only.

PC Control Software “Charge Master”

“Charge Master” will offer you unparalleled operating experience through
a computer. Real-time charging process will be presented as graphs.
You can also monitor pack voltage, cell voltage and other data during
the charging process. Initiating, charging control or firmware upgrade is
available through “Charge Master”, you are free to download on SkyRC
official website (www.skyrc.com).

Internal Independent Lithium Battery Balancer

Sky RC e660 emplo ys an individual-c ell-volt age b alancer. It' s
unnecessary to connect an external balancer for balance charging.

Balancing Individual Cells Battery Discharging

During the charging process, SkyRC e660 can automatically monitor
and balance each individual cell of the battery. Error message will be
indicated and the process will be ended immediately if the voltage of any
single one cell is abnormal.

Adaptable to Various Type of Lithium Battery

SkyRC e660 is capable of charging/discharging types of Lithium
batteries, such as LiPo, LiIon, LiFe and high voltage LiPo battery (LiHV).

Fast Charge and Storage Mode of Lithium Battery

Function of the two modes differs from each other. “FAST CHG”
minimizes battery charge time, while “STORAGE” has the capacity to
control the final battery voltage, which is necessary and helpful for a
rarely used battery.

Re-peak Mode of NiMH/NiCd Battery

In RE-PEAK mode, the charger can peak charge the battery once, twice
and three times in a row automatically. This is for confirming the battery
is fully charged.

Delta-peak Sensitivity for NiMH/NiCd

After setting the Delta peak sensitivity, when the battery voltage exceeds
the threshold, charging process will be terminated automatically.

Cycle Charging/Discharging

This charger supports cycle charge>discharger or discharge>charge for
up to 5 times. This function is extremely beneficial to a rarely used
NiMH/NiCd battery, which can help refresh and activate your battery.

Automatic Charging Current Limit

Upper limit of the charging current can be set when charging your
NiMH/NiCd battery. It's useful for a NiMH battery with low impedance
and capacity in the “AUTO” charging mode.

LiPo Voltage Battery Meter

SkyRC e660 supports checking battery total voltage, highest voltage,
lowest voltage and each individual cell voltage without external battery
meter.

Battery Internal Resistance Meter

SkyRC e660 supports checking battery total resistance and each

individual cell resistance without external resistance meter.

Capacity Limit

Charging capacity will increase as the charging goes on. If the charging
capacity exceeds the limit, the charging process will be terminated
automatically when it reaches the limit you set.

Temperature Threshold

Battery internal chemical reaction will cause the battery temperature to
rise. When the temperature limit is reached, the process will be
terminated.

This function is available by connecting optional temperature probe, which
is not included yet.

Safety Timer

Max. charging time can be set to avoid any possible defect caused by
overcharging.

DC Power Supply

Your e660 can supply DC power up to 60 Watts. You can use it to power
devices that require DC power. It converts standard household power
from 100-240V AC to 13.8V DC.

Warning and Safety Notes Warning and Safety Notes

Following warnings and safety notes are critically important,
please refer to the instructions for maximum safety; Otherwise the
charger and battery can be damaged or even cause a fire.

Never leave the charger unattended when it is connected to power
source. If any malfunction is found, TERMINATE THE PROCESS
AT ONCE and refer to the instruction manual.

Keep the charger well away from dust, damp, rain, direct sunshine
and vibration. Never drop it.

To reduce the risk of damage to the power cord, always pull by
connector rather the cord. The allowable AC/DC voltage is 110­240V AC and 11-18V DC respectively.

Operate on a hard flat nice clean smooth heat-resistant
noninflammable nonconductive surface in a well-ventilated area.
Never place the device on a carpet, car seat, or similar. Keep all the
inflammable volatile substances away from operating area.

Avoid mechanical vibration or shock as these may cause damage to
the device.

Never block the cooling fan or the air ventilation holes.

Remove all batteries and unplug the charging unit from the power
source when not in use.

Please make sure to know the specifications of the battery to be
charged or discharged to ensure it meets the requirements of this
charger. If the program is set incorrectly, the charger and battery may
be damaged. Fire or explosion may be caused due to overcharging.

Opening, disassembling, modifying, tampering with the unit may
invalidate its guarantee.

Do not misuse in any way! Use for intended purpose and function
only.

Warning and Safety Notes Warning and Safety Notes

Have you selected the appropriate program for the battery type you are
charging?

Have you set up adequate current for charging or discharging?

Have you checked the battery voltage? Please note that Lithium battery
packs can be wired in parallel or in series, i.e. a 2 cell pack can be 3.7V
(in parallel) or 7.4V (in series)

Have you checked that all connections are firm and secure?

Make sure there are no intermittent contacts at any point in the circuit.

Charging

During charge process, a specific quantity of electrical energy will be fed
into the battery, which is calculated by multiplying charge current. The
maximum permissible charge current differs on different types of battery
and its performance, which can also be found in the information by the
battery manufacturer. Only batteries to be capable of quick-charge are
allowed to be charged at higher rates than the standard charge current.

Connect the battery to the charger terminal, red is positive while black is
negative. Due to the different resistance between cable and connector,
the charger can not detect the battery pack's resistance. To work
properly for a charger, it's essential for its charge lead to be of adequate
conductor cross-section, and high quality gold-plated connectors must
be fitted to both ends.

Please always refer to the manual by battery manufacturer about
recommended ways of charging, charging current and time, especially
for a Lithium battery, which must be charged according to the instruction
strictly.

Special attention must be paid to the Lithium battery connection.

Never attempt to disassemble the battery pack arbitrarily.

Always remember: Lithium battery can be wired in parallel or in series.
In parallel connection, the battery capacity is calculated by multiplying
each individual battery cell capacity with total voltage staying the same.
Voltage imbalance may cause fire or explosion. Lithium battery is highly
recommended to charge in series.

Discharging

The main purpose of discharging is to clean residual battery capacity, or
to discharge the battery to a defined level of voltage. Final discharge
voltage must be set correctly to avoid over-discharging. Lithium battery
can not be discharged to be lower than its required minimum voltage, or
it will cause a rapid loss of capacity or a total failure. Please pay
attention to the minimum voltage of Lithium battery to protect it.

Some rechargeable batteries have memory effect. If they are partly used
and recharged before whole charging is accomplished, they will
remember this and only use that part of capacity next time. Above is
called memory effect. It is said that both NiMH and NiCd batteries suffer
from memory effect, NiCd, however, suffers more.
