Skyrc T6755 Instruction Manual page 4

MAIN FEATURES
Terminal Voltage Control (TVC)
The charger allows user to set the charge/discharge end voltage.
Battery Meter
The user can check Lithium battery's total voltage, the highest voltage, the lowest voltage and each
cell's voltage; and can check Nickel and Pb battery's total voltage.
Re-Peak Mode of NiMH/NiCd Battery
In re-peak charge mode, the charger can peak charge the battery once, twice or three times in a row
automatically. This is good for making certain the battery is fully charged, and for checking how well
the battery receives fast charges.
Delta-peak Sensitivity for NiMH/NiCd
Delta-peak sensitivity for NiMH/NiCd battery: The automatic charge termination program based on
the principle of the delta-peak voltage detection. When the battery's voltage exceeds the threshold,
the process will be terminated automatically.
Automatic Charging Current Limit
You can set up the upper limit of the charging current when charging your NiMH or NiCd battery, it is
useful for the NiMH battery of low impedance and capacity in the 'AUTO' charging mode.
Capacity Limit
The charging capacity is always calculated as the charging current multiplied by time. If the charging
capacity exceeds the limit, the process will be terminated automatically when you set the maximum
value.
Temperature Threshold*
The battery's internal chemical reaction will cause the temperature of the battery to rise. If the
temperature limit is reached, the process will be terminated.
Processing Time Limit
You can also limit the maximum process time to avoid any possible defect
PC Control Software "Charge Master"
There is a mini USB port in the charger which can be used to connect it to the PC. You need optional
USB cable (USB A Male to Mini B Male) which is not included in the package. The free "Charge
Master" software gives you unparalleled ability to operate the charger through your computer. You
can monitor pack voltage, cell voltage and other data during the charging, view charge date in real-
time graphs. And you can initiate, control charging and update firmware from "Charge Master".
When your charger is connected to computer, the "Charger Master" takes over the control of charger.
You can control and operate the charger via the "Charger Master" only.
Multi-Language and Four Color Theme Optional
There are two languages and four kinds of color theme stored in the charger and users could select
the display language and color theme as basing on personal preference.
Inner resistance of battery pack
Measure Inner resistance of battery pack inclusively all connectors and leads.
This function is available by connecting optional temper ture probe which is not included in the package.
Users can control and monitor the charge through computer when Charge Master software is installed.
You can download Charge Master software from our website www.skyrc.com

WARNING AND SAFETY NOTES
WARNING AND SAFETY NOTES
These warnings and safety notes are particularly important. Please
follow the instructions for maximum safety; otherwise the charger
and the battery can be damaged or at worst it can cause a fire.
Never leave the charger unattended when it is connected to its power supply. If any
malfunction is found, TERMINATE THE PROCESS AT ONCE and refer to the operation
manual.
Keep the charger well away from dust, damp, rain, heat, direct sunshine and vibration.
Never drop it.
The allowable DC input voltage is 11-18V DC
The allowable AC input voltage is 100-240V AC
This charger and the battery should be put on a heat-resistant, non-flammable and non-
conductive surface. Never place them on a car seat, carpet or similar surface. Keep all
flammable volatile materials away from the operating area.
Make sure you 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 up incorrectly, the
battery and charger may be damaged. Fire or explosion can occur due to overcharging.
This warranty is not valid for any damage or subsequent damage arising as a result of a
misuse or failure to observe the procedures outlined in this manual.
To avoid short circuiting between the charge lead, always connect the charge cable to the
charger first, then connect the battery. Reverse the sequence when disconnecting.
Never attempt to charge or discharge the following types of batteries:
A battery pack which consists of different types of cells (including different manufacturers)
A battery that is already fully charged or just slightly discharged
Non-rechargeable batteries (pose an explosion hazard)
A faulty or damaged battery
A battery fitted with an integral charge circuit or a protection circuit
Batteries installed in a device or which are electrically linked to other components
Batteries that are not expressly stated by the manufacturer to be suitable for the
currents the charger delivers during the charge process
Please bear in mind the following points before commencing charging:
Did you select the appropriate program suitable for the type of battery you are charging?
Did you set up adequate current for charging or discharging?
Have you checked the battery voltage? Lithium battery packs can be wired in parallel and
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.
