- Optimised operating software
When charging or discharging, BC6 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.
- Dual input power
BC6 employs the circuit that can be operated with the input power of AC(Alternating Current) or
DC(Direct Current). For AC input, it contains a AC-DC switching power supplier which has 5A of
power capacity and maximum output power of 50Watts for charging. As a result, it can charge up to
15 cells of NiCd/NiMH and 6 series of Lithium batteries with maximum current of 5.0A. But there
might be the limit of feeding current to a higher voltage of battery. Please refer 'Maximum circuit
power charge'.
- Individual voltage balancer for Lithium batteries inside
BC6 has an individual-cell-voltage balancer inside. So it does not need any balancer separately
when charging Lithium batteries (LiIo/LiPo/LiFe) for cell voltage balancing.
- Balance individual cells on discharge
BC6 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
BC6 can accept three types of Lithium batteries - LiIo, 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 charge current to avoid from high current feeding . This is very useful when charging
the low impedance and small capacity NiMH battery in 'AUTO' mode.
Capacity limit: The charging 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
Thank you for purchasing the e-STATION BC6 'Dual power'. You get a rapid charger/discharger

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 drop it.
The circuit of the unit is designed to be powered by 12V DC or 100V~240V AC. But do not
supply both input power simultaneously. The circuit can be damaged permanently.
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 sequence when
disconnecting.
Do not connect more than one battery pack to the charge lead at any one time.
Do not attempt to charge or discharge the following types of battery.
- Battery pack, which consists of different types of cell (including different manufacturers).
- Battery, which is already fully charged or just slightly discharged.
- Non-rechargeable batteries (Explosion hazard).
- Batteries that require a different charge technique from NiCd, NiMH, LiIo, LiPo, LiFe or Pb.
- Faulty or damaged battery.
- 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 of checking the following point before charge operation.
- Did you select the appropriate program, which are suitable for the type of battery?
- Did you set up adequate current for charging or discharging?
- Lithium battery pack can be composed with parallel and series circuits mixed. You have to
check the composition of the battery pack carefully before charging.
- Are all connections firm and safe, or is there an intermittent contact at any point in the circuit?
Charging
A specific quantity of electrical energy is fed into the battery during charge process. The charge
quantity is calculated by multiplying charge current by charge time. The maximum permissible
charge current varies according to the battery type or its performance, and can be found in the
information provided by the battery manufacturer. It is only allowed to charge batteries at rates
higher than the standard charge current if they are expressly stated to be capable of quick-charge.
- Connect the battery to charge to output terminal of the charger using suitable charge lead. They
are red, positive (+) and black, negative (-). Since the charger cannot detect the difference
between the internal resistance of the battery pack, cable resistance and connector transfer
resistance, the first requirement if the charger to work properly is that the charge lead should be of
adequate conductor cross-section. And also high-quality connectors (normally gold-contact type)
must be fitted to both ends.
- Refer to the information provided by the battery manufacturer regarding charging methods, and
verify the recommended charge current and charge time. Especially for Lithium batteries, you
have to follow the charge instruction provided by the manufacturer strictly.
- 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 been 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)
BC6 will be operated with the default value of the essential user settings when it is connected to a
12V battery or a AC wall socket 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 key to make it blink then
change the value with or key. The value will be stored by pressing key once.
The screen displays the nominal voltage of Lithium
battery. There are three kinds of Lithium battery;
LiFe(3.3V), LiIo(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.
BC6 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.

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. Please refer the statement in below to
calculate the time setting.
This program sets the maximum charge capacity that will
be supplied to the battery during charge. If the delta-peak
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.

Safety Timer Calculations
When charging NiCd or NiMH batteries, divide the battery's rated capacity (mAh) by the charge
current (A). And divide the result by 11.9. Set this number of minutes in the safety timer setting. If the
charger stops charging at this time limit by any reason, approximately 140% of the battery's capacity
will have been delivered to the battery. For example:
Capacity Current Safety timer setting
2000mAh 2.0A (2000 / 2.0 = 1000), divided by 11.9 = 84 minutes
3300mAh 3.0A (3300 / 3.0 = 1100), divided by 11.9 = 92 minutes
1000mAh 1.2A (1000 / 1.2 = 833), divided by 11.9 = 70 minutes

Lithium battery (LiIo/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 LiIo, and 3.6V 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 key to make it blink
then change the value with or key. The value will be stored by pressing key once.
The left side of the first line shows the type of battery
you select at the users setting. The value on the left
side of second line sets a charge current and the value
on the right side of second line sets the voltage of the
battery pack.
After setting the current and voltage press key for
more than 3 seconds to start the process.

This is for balancing the voltages of Lithium batteries of the battery pack to be charged. To do this,
the battery pack being charged should have the individual cell connector. And connect it to the
individual port at the right side of charger with a suitable connection cable that fits with your battery
pack. And also, you need to connect the battery output plug to the output of charger.
In this mode, the charging process will be different from ordinary charging mode. The internal
processor of the charger will monitor the voltages of each cell of the battery pack and controls the
charging current that is feeding to each cell to normalise the voltage.
The value on the left side of second line sets a charge
current and the value on the right side of second line
sets the voltage of the battery pack.
After setting the current and voltage press key for
more than 3 seconds to start the process.
This shows the number of cells you set up and the

The charging current is getting smaller as the process goes to the near end term of Lithium
battery charging. To finish charging process earlier, this program eliminate certain term of CV
process. Actually, the charging current will goes to 1/5 from the initial value to end the process
while the normal charging goes to 1/10 during CV term. The charging capacity may be a bit
smaller than normal charging but the process time will be reduced.
This is for charging or discharging Lithium battery not to be used for the time being. The program
will determine to charge or discharge the battery to the certain voltage depending on the voltage of
the battery at its initial stage. They are different from the type of the battery, 3.75V for LiIo, 3.85V
for LiPo and 3.3V for LiFe per cell. If the voltage of battery at its initial stage is over the voltage
level to storage, the program will start to discharge.
You can set up the current and the voltage of the
battery pack to be charged. The current will be used for
charge or discharge the battery to reach the 'storage'
level of voltage.

* Voltage balancing and monitoring during the discharge
The processor monitors the voltage of individual cells during 'storage-mode' and 'discharge'
of Lithium battery pack. It tries to normalise the voltages to be equal. For this feature, the
individual plug of the battery pack should be connected to the individual port of the charger.
If the voltage of any one or more cells varies abnormally during the procedure, BC6
terminates the process forcibly with the error message. If this happens, the battery pack
contains the bad cell, or the bad connection of the cable or plug. You can easily know which
one cell is bad by pressing button at time of showing the error message.

The processor found that the voltage of one of the
cell in the Lithium battery pack is too low.
In this case, the 4th cell is bad. If there happens
the connection-break of the cable or plug, the
voltage value may show zero.

display, press key to make it blink then change the value using or key. The value will
be stored by pressing key once.
To start the process, press button for more than 3 seconds.
This program simply charges the battery using the current
you set. In 'Aut' mode, you need to set the upper limit of
charge current to avoid from higher feeding current that
may damage the battery. Because some batteries of low
impedance and small capacity can lead to the higher
charge current by the processor at automatic charge
mode. But in 'Man' mode, it will charge the battery with the
charge current you set at the display. Each mode can be
switched by pressing and button simultaneously
when the current field is blinking.

Glossary of terms
Amps(A): The unit of measure for charge or discharge electric current. The program of the charger
will show most of the current in amps(A) at its LCD screen.
Milli-amps(mA): The electric current, being amps(A) multiplied by 1000 and noted as 'mA'. So
2.0A is the same as 2000mA (2.0x1000). Or, to convert mA to amps, divide the mA number by
1000. So 200mA is the same as 0.2A. If a current value is below 1.0A, the LCD screen of the
charger will still show the current in amps, not milli-amps. For example, a current of 600mA will be
displayed as 0.6A, and a current of 100mA will actually be shown as 0.1A.
Capacity,milli-amp hours (mAh), and amp-hours (Ah): Charge energy stored by a battery is
called capacity, which is defined as how much current a battery can supply constantly over one
hour of time. Most hobby batteries are rated for capacity in 'mAh' or milliamp hours. A 650mAh
battery can deliver 650mA of current for one hour (650mAx1hr = 650mAh). The batteries of very
large capacity, such as lead-acid(Pb) batteries, are usually rated in 'Ah' or amp-hours. A '12V 60Ah'
car battery can deliver 60 amps of current for one hour (60Ax1hr = 60Ah).
Nominal voltage(V): The nominal voltage of the battery pack can be determined as follows;
-.NiCd or NiMH: multiply the total number of cells in the pack by 1.2. A 8-cell pack will have a
nominal voltage of 9.6 volts (8x1.2).
-.LiPo: multiply the total number of cells in the pack by 3.7. A 3-cell LiPo wired in series will have a
nominal voltage of 11.1 volts (3x3.7).
-.LiIo: multiply the total number of cells in the pack by 3.6. A 2-cell LiIo wired in series will have a
nominal voltage of 7.2 volts (2x3.6).
-.LiFe: multiply the total number of cells in the pack by 3.3. A 4-cell LiIo wired in series will have a
nominal voltage of 13.2 volts (4x3.3).
If the nominal voltage of the battery is not printed on the battery's label, consult your battery
manufacturer or supplier. Do not guess the rated voltage of battery.
'C'-rating: Capacity is also referred to as the 'C' rating. Some battery suppliers recommend charge
and discharge currents based on the battery 'C' rating. A battery's '1C' current is the same number
as the battery's rated capacity number, but noted in mA or amps. A 600mAh battery has a 1C
current value of 600mA, and a 3C current value of (3 x 600mA) 1800mA or 1.8A. The 1C current
value for a 3200mAh battery would be 3200mA (3.2A).
