warning and safety notes

9
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 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,
recommended charging current and charging current and charging time. Especially, the
Lithium battery should be charged according the charging instruction provided by the
manufacturer strictly.
Attention should be paid to the connection of Lithium battery especially.
Do not attempt to disassemble the battery pack arbitrarily
warning and safety notes

10
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 battery's capacity by the number of cell with total voltage stay the same. The
voltage's imbalance may cause fire or explosion. Lithium battery is recommended
to charge in series.
Discharging
The main purpose of discharging is to clean 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 charging. The final discharge voltage should be set up
correctly to avoid deep-discharging.Lithium battery can not be discharged to lower
than the minimum voltage, or it will cause a rapid loss of capacity or a total failure
.Generally, Lithium battery doesn't need to be discharged. Please pay attention to
the minimum voltage of Lithium battery to protect the battery.
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 NICd and NiMH batteries
are suffering from memory effect .NiCd has more memory effect than NiMH.
Lithium batteries are recommended to be discharged partially rather than fully
discharged. 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 used 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 screen shows the nominal voltage of Lithium battery. There
are three kinds of Lithium battery: LiFe (3.3V),Lilo (3.6V) or LiPo
(3.7V). This information is of critical importance that you have to
check the battery carefully to make sure it is set up correctly. If it
is different from correct value, explosion can occur during charge
process.
To avoid from erroneous setting by users, RC-6S detects the cell
count of Lithium battery automatically at the beginning of charge
or discharge process. But battery that is deep-discharged can’t
be detected correctly. To avoid this error, the time term can be set
to verify the cell count by the processor. Normally, 15 seconds
are enough to detect the cell count correctly. You need to extend
the time term limit for the battery of large capacity. But the charge
or discharge process may come to an end if you set too long time
limit for the battery of small capacity. This may cause fatal error.
You have to extend the time term if the processor process.
Otherwise, default value is recommended to use.
This shows the trigger voltage for automatical charge termination
of NiMH and NiCd battery. the valid value ranges from 5 to 20 mV
per cell. Setting the trigger voltage higher brings a danger of
overcharging; whereas setting it lower brings a possibility of
premature termination. Please refer to the technical specification
of the battery. (NiCd default:12mV, NiMH default:7 mV)

WARNING AND SAFETY NOTES

There is a 3-pin port on the left of the charger used as USB interface or temperature
sensor port. If the screen displays temperature, you can use the optional temperature
probe to connect to the surface of the battery. If it is set as the USB port, you can connect
the charger to your PC through the optional USB cable to monitor the charging process
through optional software. The maximum temperature of the battery can be set during
the charge process. The process will be terminated automatically to protect battery once
the temperature of battery reaches this value. This feature is accomplished through
temperature probe (optional).
The battery becomes warm after cycles of charge/discharge process. The
program will insert a time delay after each charge/discharge process to
allow the battery enough time to cool down before beginning next cycle of
charge/discharge process. The valid value ranges from 1 to 60 minutes.
When the charge process starts, the integrated safety timer starts to run
simultaneously. If error detected or the termination circuit can not detect
overcharging. Please refer to the below statement to calculate the timer
you set.
The program provides maximum capacity protection function. If the Delta-
peak voltage can not be detected or the safety timer times out, the
charge process will stop automatically, when the battery reaches the
use-set maximum charge capacity.
The beep to confirm user’s operation sounds every time a button is
pressed. The keep or melody sounds at various times during operation to
confirm different mode change. These functions can be switched on or
off.
This function monitors the voltage of the input battery used to power this
charge. If the voltage is lower than user-set value, the program will end
forcibly to protect the input battery.

Safe timer calculation
When charging NiCd or Nimh batteries, divide the capacity by current, then divide
the result by 11.9, set this number of minutes as the value for safety timer setting. If
the charger stoppied at this time threshold, about 140% of the capatity will have
been fed into the battery.
For example:
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
Lithium (LiIo/LiPo/LiFe) program
The program is only suitable for charging/discharging Lithium-polymer batteries
with a nominal Voltage of 3.3/3.6/3.7V/cell. Different batteries have different charge
technique. There are two methods termed as constant voltage and constant
current. The charge current varies according to battery capacity and specification.
The final voltage is very important; it should precisely match the voltage of the
battery: LiPo is 3.6V, LiLo is 4.1V, and LiFe is 3.6V. The current and voltage of the
battery should be correctly set.
When you want to change the values of parameters, please press START/ENTER
key to make it blink and then use DEC or INC to change the value. Then press
START/ ENTER key again to store the value.
SAFE TIMER CALCULATION

The left side of the first line shows the type of battery you

This displays the number of cells you set up and the processor
detects. “R”shows the number of cells detected by the charger
and “S” is the number of cells set by you at the previous screen.
If both numbers are identical you can start charging by press
START/ENTER button. If not, press BATTERY/STOP button to
go back to previous screen to carefully check the number of
cells of the battery pack before going ahead.
This screen shows the real-time status during charge process.
Press BATTERY/STOP key once to stop the charge process.
Charging lithium battery in the balance mode
This function is for balancing the voltage of Lithium-polymer battery cells while charging.
In the balance mode, the battery needs to have a balance lead to connect the individual
port at the right side of the charger. And you need to connect the battery’s out put plug to
the output of charger.
Charger in this mode is different from the normal modes, because the built-in processor
monitors voltage of individual cell and control input current fed into each cell to normalize
the voltage.
