- Operating software
Every operating program in the unit is controlled with mutual links and
communications to prevent every possible error, so it introduces the maximum safety,
such as input voltage warning, reverse polarity protection and Lithium cell-count input
error warning. The entire firmware can be upgraded via USB from internet download at
our web page, when there needs to be changed.
- High-power and high-performance circuit
BC6HP employs the circuit that has maximum output power of 250Watts. As a result,
it can charge or discharge up to 18 cells of NiCd/NiMH and 6 series of Lithium batteries
with maximum current of 10A. Furthermore, the cooling system is so efficient that can
hold such a power without any trouble running the circuit or the operating program.
- Accept various types of Lithium battery
BC6HP 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 feeding high current to the
battery. 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 you set the maximum value.
Thank you for purchasing the e-STATION BC6HP charger. You get a rapid
charger/discharger with integrated balancing circuit, which is computerised with a high
performance microprocessor and specialised operating software. Please read this
operating manual completely and attentively as it contains a wide variety of specific
programming and safety information.

Initial parameters setup (User Program Setup)
BC6HP will be operated with the default value of the essential user settings when it is
connected to a 12V DC input power source 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 ‘ENTER/START’
button to make it blinking, then change the value using ‘INC’ or ‘DEC’ button. The value
will be stored by pressing ‘ENTER/START’ button once.
BC6HP recognises the cell count of Lithium battery
automatically at the beginning of 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 recognizes 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.

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.
(Disable, Delicate, Default, 5mV~20mV/cell)
Disable; The charger would not detect Delta-peak
voltage for termination. To terminate charging process,
the charger will check the parameters set up at other
safety parameters like max. capacity, safety timer or
safety temperature. If any one has been reached at its
limit, the charging process will be terminated. (for NiMH
only)
Delicate; The charger will detect a very small variation
at delta-peak voltage. Some NiMH batteries which

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-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 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 at end of 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, 3.7V for LiIo, 3.8V 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 first.
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.

be connected to the individual port of the charger. If the voltage of any one or more
cells varies abnormally during discharge, BC6HP terminates the process forcibly with
the error message. If this happens, the battery pack contains a bad cell, or bad
connection of the cable or plug. You can easily know which one cell is not normal by
pressing ‘INC’ button at time of showing the error message.

These programs are for charging or discharging NiMH (Nickel-Metal-Hydride) or NiCd
(Nickel-Cadmium) battery commonly used for R/C model applications.
This program simply charges the battery using the
current you set. You can select charge current mode in
‘A’(automatic) or ‘M’(manual). In ‘Auto’ 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.
- Press ‘ENTER/START’ button to make ‘M’ or ‘A’
blinking.
- Change the current mode to ‘M’ or ‘A’ using ‘INC’ or
‘DEC’ button.
- Press ‘ENTER/START’ button to alter the charge
current.
- Change the current value using ‘INC’ or ‘DEC’ button.
- Press ‘ENTER/START’ button for more than 3
seconds to start charging.

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).
