WARNING AND SAFETY NOTES
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.

Charging
During charge process, a specific quantity of electrical energy is
fed into the battery. The charge quantity is calculated by multiplying
charge current by charge time. The maximum permissible charge
current varies depending on the battery type or its performance,
and can be found in the information by the battery manufacturer.
Only batteries that are expressly stated to be capable of quick-
charge are allowed to be charged at rates higher than the standard
charge current.
Connect the battery to the terminal of the charger: red is positive
and black is negative. Due to the difference between resistance of
cable and connector, the charger can not detect resistance of the
battery pack, the essential requirement for the charger to work
properly is that the charge lead should be of adequate conductor
cross-section, and high quality connectors which are normally gold-
plated should be fitted to both ends.
Always refer to the manual by the battery manufacturer pertaining
to charging methods. Operate according to their recommended
charging current and charging time. lithium batteries, in particular,
should be charged strictly according to the manufacturer’s
instruction.
Close attention should be paid to the connection of lithium
batteries.
Do not attempt to disassemble the battery pack arbitrarily.
Please get highlighted that lithium battery packs can be wired in
parallel and in series. In the parallel connection, the battery's
capacity is calculated by multiplying single the battery's capacity by
the number of cells, bearing in mind that total voltage stays the
same. If the voltage is imbalanced, it may cause a fire or explosion.
Lithium batteries are recommended to charge in series.
WARNING AND SAFETY NOTES WARNING AND SAFETY NOTES
Discharging
The main purpose of discharging is to clean the residual capacity
of the battery, or to reduce the battery' voltage to a defined level.
The same attention should be paid to the discharging process as
the charging process. The final discharge voltage should be set up
correctly to avoid deep discharging. Lithium batteries cannot be
discharged to lower than the minimum voltage, or it will cause a
rapid loss of capacity or a total failure. Generally, lithium batteries
don't need to be discharged. Please pay attention to the minimum
voltage of lithium batteries to protect them.
Some rechargeable batteries have a memory effect. If they are
partly used and recharged before the whole charge is
accomplished, they remember this and will only use that part of
their capacity next time. This is a 'memory effect' It is said that
NiMH and NiCd batteries are suffering from memory effect. NiCd
has more ‘memory effect’ than NiMH.
Lithium batteries are recommended to be discharged partially
rather than fully. Frequent full discharging should be avoided if
possible. Instead, charge the battery more often or use a battery of
larger capacity. Full capacity cannot be reached until it has been
subjected to 10 or more charge cycles. The cyclic process of
charge and discharge will optimize the capacity of battery pack.

The charger can test motor RPM. Please do as follows,
Connect the motor and ESC.
Switch off the ESC and connect it to the battery.
Connect the power to the charger.
Insert the ESC signal wire to ESC port in the charger.
Connect the motor and charger with motor sensor wire. There is a motor
sensor port beside the temp sensor.
Enter Motor RPM Tester Program, set the initial pulse width which should be
the same as the neutral position of the transmitter. We suggest to set it to 1480
as most of the transmitters’ neutral position is like that.
Switch on the ESC. Change the pulse width and check the RPM corresponding
to different pulse width. If the motor doesn’t run, please recheck the transmitters’
neutral position and reset the initial pulse width.
Press the Start/Enter dial to enter the Motor RPM Tester
Program and set the initial pulse width by rotating the
Start/Enter knob.
Switch on the ESC.
The left side of the first line shows the pulse width and
the second line shows the RPM of the motor
corresponding to different pulse width. The value of
pulse width can be changed by rotating the Start/Enter
dial.

SYSTEM SET UP
It will be operated with the default value of the essential user settings
when it is connected to a DC 11~18V battery for the first time. The
screen displays the following information in sequence and the user can
change the value of parameter on each screen.
When you are willing to alter the parameter value, press the dial to
make it blink then change the value by rotating the dial clockwise or
counterclockwise. The value will be stored by repressing the dial.
User set up starting screen.
The battery is on the cyclic process of charge
and discharge can often become warm after
charge or discharge period. The program can
insert a time delay to occur after each charge
and discharge process to allow the battery
adequate time to cool down before being
subjected to the next process. The value
ranges from 1 to 60 minutes.
When you start a charge process, the integral
safety timer automatically starts running at the
same time. This is programmed to prevent
overcharge the battery if it proves to be faulty,
or if the termination circuit cannot detect the
battery full. The value for the safety timer
should be generous enough to allow a full
charge of the battery.
Safe timer Calculation
When charging NiMH or NiCd batteries, divide
the capacity by current, then divide the result
32 33
G6P G6P
Capacity Current Safety Time
2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes
3300mAh 3.0A (3300/3.0=1100)/11.9=92 minutes
1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes
For example:
This program sets the maximum charge
capacity that will be supplied to the battery
during charge. If the deltapack voltage is not
detected nor the safety timer expired by any
reason, this feature will automatically stop the
process at the selected capacity value.
The beep sounds at every time pressing the
buttons to confirm your action. The beep or
melody sounded at various times during
operation to alert different mode changes.
These audible sounds can be on or off.
This program monitors the voltage of input
battery. If the voltage drops below the value
you set the operation forcibly terminated to
protect the input battery.
This screen shows the external and internal
temperature.
by 11.9, set this number as the value for
safety timer setting. If the charger stopped at
this threshold, about 140% of the capacity will
have been fed into the battery.
