FOR NICD/NIMH/LITHIUM/PB BATTERIES
Operating Manual
Thank you for purchasing the balance charger. This is a rapid
charge/discharger with built in balancer, computerised with
microprocessor and specialised operating software. Please
read this entire operating manual completely and attentively
before using.
Features
Optimised operating software
When charging or discharging, it has an ‘AUTO’ function that sets the
feeding current automatically. Especially for Lithium batteries, it can prevent
the over-charging can lead to an explosion by users fault. Every program in
the unit is controlled with mutual links and communication for every possible
error so it introduces a maximum safety. These can be set at users option.
Special recharge plugsport for receiver,transmitter and igniter charger. And
for frequently used charger port such as multi purpose crocodile pin etc.
It provides most convenient balance charge port for Lithium batteries, with
separated 3,4,5,6 charge port, and external reverse connector.
High-power and high-performance circuit
It employs the circuit that has maximum output power of 50W. As a result it
can charge or discharge up to 15cells of NiCd/NiMH and 6 series of Lithium
batteries with maximum current of 6.0A. Furthermore the cooling system is
so efficient that can hold such a power without any trouble of running the
CPU or the operating program.
Individual voltage balancer for Lithium batteries insideh
It has an individual-cell-voltage balancer inside.This does not require any
extra balancer separately when charging Lithium batteries(Lilo/LiPO/LiFe)
for cell voltage balancing.
Balance individual cells on discharge
It also can monitor and balance individual cells of the Lithium battery pack
during the discharge process. If the voltage of any one cell varies abnormally,
the process will be stopped with the error message.
Accept various types of Lithium battery
It can accept three types of Lithium batterles- Lilo, LiPo and LiFe. They have
different characteristics by their chemistry. You can select any one of them
that you are going to process before the job. For their specifications,
refer‘Warnings and safety notes’section.
Lithium battery ‘Fast’and ‘Storage’mode
You can charge Lithium battery for special purposes. ‘Fast’charge reduces
the charging time of Lithium battery and ‘Storage’mode controls the final
voltage of the battery to be suit for long time storage.
Maximum safety
Delta-peak sensitivity: The automatic charge termination program works on
the principle of the Delta-peak voltage detection.(NiCd/NiMH)
Auto-charge current limit: When charging NiCd or NiMH at ‘AUTO’current
mode, you can set the upper limit of change current to avoid from high
current charging. This is very useful when charging the low impedance and
small capacity NiMH battery in “AUTO’mode.
Capacity limit: The changing capacity always calculated by multiple of the
charging current and time. If the charging capacity exceeds the limit the
process will be terminated automatically when you set the maximum value.
Temperature limit(*): The temperature of the battery on charging will rise by
its internal chemical reaction. If you set the limit of temperature the process
will be expired forcibly when the limit has reached.
Processing time limit: you can also restrain the maximum process time to
prevent from any possible defect.
Input power monitor: To protect the car battery using as input power from
being damaged the voltage of it always monitored. If it dorps below the lower
limit the process will be ended automatically.
Automatic cooling fan: The electric cooling fan comes into action automatically only when the internal temperature of the unit is raised.
Data store/load
For users convenience it can store maximum 5 data of different batteries.
You can establish the data contains program setting of the battery to charge
or discharge continually. These data can be called out at any time you need
and the process can be executed without program setting.
Cyclic charging/discharging
Perform 1 to 5 cycles of charge>discharge or discharge>charge continually
for battery refreshing and balancing.

Warnings and safety notes
�Never leave the charge unsupervised when it is connected to its power
supply. If any malfunction is observed immediately terminate the process and
refer to the operation manual.
�Keep away the unit from dust, damp, rain, heat direct sunshine and
vibration. Do not dorp it.
�The circuit of the unit is designed to be powered by a 10-18V DC only.
�This unit and the battery to charge or discharge should be set up on a
head-resistant, non-inflammable and non-conductive surface. Never place
them on a car seat, carpet or similar. Keep all the inflammable volatile materials well away from operating area.
�Be sure to understand the information of the battery to be charged or
discharged accurately. If the program is set up incorrectly the battery can
severely be damaged. Especially Lithium battery can cause a fire or an
explosion by over-charging.

�To avoid short-circuits between the charge lead, always connect the charge
cable to the unit first and only then to the battery to be charged or discharged.
Reverse the hsequence when disconnecting.
-Do not attempt to disassemble the battery pack arbitrarily.
You have to pay attention to verify the capacity and the voltage of the Lithium
battery pack. It may be composed of parallel and series connection mixed. In
parallel link the capacity of the battery pack is multiplied by the number of
cells but the voltage remains same. That kind of voltage imbalance causes a
fire or explosion during charge process. We recommend you compose the
Lithium battery pack in series only.
Discharge
The typical purpose of discharge is to determine the residual capacity of the
battery, or to lower the voltage of battery to a defined level. When you
discharge the battery you also have to pay attention on the process same as
charging. To avoid the battery becoming deep-discharged, set the final
discharge voltage correctly. Lithium batteries should not be deep-discharged
to lower than the minimum voltage, as this leads to a rapid loss of capacity or
a total failure. Generally, you do not need to discharge Lithium battery
voluntarily.
-Some rechargeable batteries are said to have a memory effect. If they are
partly used and recharged before the whole charge is drawn out,
they‘remember’ this and next time will only use that part of their capacity. This
is a ‘memory effect’. NiCd and NiMH batteries are said to suffer from memory
effect. They prefer complete cycles; fully charge then use until empty, do not
recharge before storage-allow them to self-discharge during storage. NiMH
batteries have less memory effect than NiCd.
-The Lithium battery prefers a partial rather than a full discharge. Frequent
full discharges should be avoided if possible. Instead, charge the battery
more often or use a larger battery.
-The brand-new NiCd battery pack is partially useful with its capacity until it
has beeen subjected to 10 or more charge cycles in any case. The cyclic
process of charge and discharge will lead to optimise the capacity of battery
pack.
Those warnings and safety notes are particularly important.
Please follow the instructions for a maximum safety; otherwise the charger and the battery can be damaged violently.
And also it can cause a fire to injure a human body or to lose
the property.

Initial Parameter set up (Users set up)
It will be operated with the default value of the essential user settings when
it is connected to a 12V batttery 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 in the program, press
start/enter key to make it blink then change the value with INC or DEC key.
The value will be stored by pressing start/enter key once.
The screen displays the nominal voltage of
Lithium battery. There are three kinds of
Lithium battery; LiFe(3.3V),Lilo(3.6V) or
LiPo(3.7V). This is very important so you have
to check the battery carefully and set it up
correctly. If it is different from correct value the
battery can explode during charge process.
It recognise the cell count of Lithium battery
automatically at the beginning of charge or
discharge process to avoid from erroneous
setting by user. But deeply discharged battery
can be perceived incorrectly. To prevent the
error, you can set the time term to verify the
cell count by the processor. Normally, 10
minutes are enough to perceive the cell count
correctly. For the battery of larger capacity, you
may extend the time term. But if you set the
time term too long for the battery of smaller
capacity, the charge or discharge process can
be finished within the time term with the
erroneous cell count. This may cause the fatal
result. If the processor recognises the cell
count incorrectly at the beginning of charge or
discharge process, you may extend the time.
Otherwise, you had better use with the default
value.
This shows the trigger voltage for automatic
charge termination of NiMH and NiCd battery.
The effective value ranges from 5 to 20mV per
cell .if the trigger voltage is set higher, there is
a danger of overcharging the battery; if it is set
lower, there is a possibility of premature
termination. Please refer the technical specification of the battery.(NiCd default:12mV, NiMH
default:7mV)
You can select the function of 3-pin port at left
side of the unit.It can be used temperature
sensor port or USB port, selected at this
screen. If the port is assigned as a temp. port,
an optional temperature probe contacting the
surface of battery can be used. When it is
selected as an USB port, you can link the
charger to your PC via an optional USB cable.
This can utilize the optional software that can
show you the charge process at PC.
You can set the maximum temperature at
which the charger should allow battery to
reach during charge. Once a battery reaches
this temperature during charge, the process
will be terminated to protect the battery.
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 .
This program sets the maximum charge
capacity that will be supplied to the battery
during charge. If the delta-pack 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.
Lithium battery(Lilo/LiPo/LiFe)program
These programs are only suitable for charging and discharging Lithium
batteries with a nominal voltage of 3.3V, 3.6V and 3.7V per cell. These batteries need to adopt different charge technique is termed a constant
voltage(CV) and constant current(CC) method. The charge current varies
according to the battery capacity and performance. The final voltage of
charge process is also very important; it should be precisely matched with
the charade voltage of the battery. They are 4.2V for LiPo, 4.1V for Lilo, and
3.6 V for LiFe. The charge current and nominal voltage as for cell count set
on the charge program must always be correct for the battery to be charged.
When you are willing to alter the parameter value in the program, press
Start/Enter key to make it blink then change the value with INC or DEC key.
The value will be stored by pressing Start/Enter key once.
