Warnings and Safety Tips
The following safety tips are essentially important. Please strictly follow the manual’s
instructions in operation to guarantee safety. Improper operation or incorrect working
parameter settings may cause damages to the charger and battery and/or result to a fire.
Do not use the charger in an unattended manner; in case of any functional abnormi-
ty, please stop using it and refer to the manual.
Keep the charger away from dust, humidity, rain and high temperature, as well as
avoid direct exposure to the sun and intense vibration.
Make sure the heat emission hole at the bottom of the charger is uncovered while
in use, and ensure the cooling fan smoothly extracts heat.
Please fully understand the charging and discharging characteristics as well as the
battery’s specifications. Additionally, set up proper charging parameters in the
charger. Incorrect setting of parameters can cause damage to the charger and
battery and/or result to disastrous consequences such as fire or explosion.
Make sure input voltage for D2 is AC 100-240V.
Please place the charger on a heat-resisting, non-flammable and insulating
surface. Do not use it by placing it on the car’s seats, carpet or other similar places.
Keep inflammable and explosive objects away from operation areas of the charger.
When charging or discharging is completed, please press the speed shuttle key to
terminate current task, and remove the battery when the charger shows the standby
screen.

How to Confirm Charging Current
It is very important to know the maximum charging current of the battery as excessive
current could influence the life span of battery and/or cause damages. In addition, exces-
sive current can cause heating and/or explosion of the battery during the charging
process.
The charging and discharging capacity of battery is usually marked with C value. Multiply-
ing the charging C value and battery capacity equals to the maximum charging current
supported by the battery. For example, for a 1000 mAh battery with a charging capacity of
5C, the maximum charging current would be 1000*5=5000mA; therefore, the maximum
charging current is 5A.
For a lithium battery, if it is impossible to confirm the supported charging C value, please
set the charging current below 1C for the sake of its (lithium battery) safety.
The reference relation between C value and charging time: charging time ≥60 minutes/
charging C value (it therefore needs around 60~70 minutes to complete charging with 1C).
Due to differences in battery conversion efficiency, the period to complete the charging
might be extended.

Task Setting

The charger is equipped with a function of measuring the cells’ internal resistance,
which is only applied when conducting balanced charging. The cell voltage should
be measured and calculated within 2 to 3 minutes after the charging task has been
initiated. The battery internal resistance can slightly vary under different electric
quantities while the measured resistance value is usually relatively low as the
electric quantity is large.
The charging current should be adjusted instantly as the charger measures the
internal resistance of the battery; therefore, it is normal phenomenon for acute
change of current to occur during charging.
Internal resistance measurement function

The working mode of the charger is series charging; you must therefore connect it to the
output line of the battery while charging. For a lithium battery, it is highly suggested that
the balanced interface should be connected to carry out balanced charging to accurately
monitor the voltage of each cell and balance the ones with bad consistency.
If battery voltage is lower than storage voltage, charger will charge battery to
storage voltage. If battery voltage is higher than storage voltage, charger will
discharge battery to storage voltage. In order to save storage time, battery might not
be accurately balanced, this is normal and there will not do any harm to battery.
Storage functions
Activation and restoration functions of excessive discharged battery
When the charging task begins, one tenth of the setting current should be applied
to activate and restore the battery if the cell voltage is tested to be lower than the
pre-charge voltage; on the other hand, it should be adjusted to a rated voltage for
charging when the cell voltage is higher than the pre-charge voltage. This design
can protect excessively discharged batteries, as well as conduct activation and
restoration.

Since the way of internal resistance measurement varies, it cannot be realized to
measure the absolute value as professional internal resistance tester does. There-
fore, the internal resistance value can only be referred to when conducting horizon-
tal comparisons, such as judging the consistency of the cells’ performance or
making comparisons of the performance of different cells. The charging current is
an influential factor for measuring internal resistance; batteries with large capacity
and small internal resistance would relatively need large charging currents to accu-
rately measure the internal resistance.
During the charging process, the screen displays an orange marking which turns
into green or blue as the charging is completed. When the charging completes, the
cells’ voltage difference should be smaller than 20mV, while the screen marking
turns into green. Therefore, if the battery is in urgent use, it’s okay to stop charging.
The charger should continue to balance the battery if the charging process is not
terminated, and the screen light turns blue, since the voltage difference is smaller
than 10mV. Additionally, the charger should continue to carry out accurate balancing
of the battery after the light turns blue. If the consistency of the cells is excellent, the
screen light should skip color green to become blue as the charging is complete.
After the charging is complete, it is normal for voltage decline to occur due to differ-
ent performances. As the number of the charge cycle grows, the performance
decreases, and the voltage decline phenomenon becomes obvious. To charge the
battery with a larger current would also cause a more obvious voltage decline after
the charging is complete.
NB: When charging the battery in a hurry in outdoors, it is okay to stop charging
when the screen light turns green. If there is enough time and the cells are assumed
to be well balanced, it is better to stop charging when the screen light turns blue;
alternatively, wait a little longer after that to gain more accurate balance effects.

single channels operation can reach 200w
both channels simultaneously initiate task would get 100w for each

150w, if task needs less than150w, remaining power will go into the other channel
automatically.
During dual Charging operation, current adjust in a channel will get that channel

Troubleshoot
Error in power on self-testing: the charger can automatically carry out a self-testing
when connected to a power supply. A self-testing error warning sound should be
heard when the charger is connected to the battery; power on after removing the
battery for 5 minutes.
Error for abnormal battery connection: pull out and plug in the battery again to
ensure all connections are reliably contacted; if the error reminder continues,
please check whether the metal parts on the battery interface are oxidized or
burned resulting in unreliable connection.
17
For electronic products with this marking in their manuals, please separately
dispose them with family garbage. When a charger gets spoilt and cannot be
used anymore, please take it to a nearby garbage station or recycle center.
