How to Confirm Charging Current
Operative Skills
Operation and Setup
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, excessive
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. Multiplying
the charging C value and battery capacity equals to the maximum charging current support-
ed 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 Settings and Notes
Operation and Setup
The D6 Pro AC/DC Dual Channel Smart Charger is operation in a series charging mode. When
connecting the battery, the battery output cable must be connected. For lithium batteries, it is
strongly recommended to connect the balance ports for balanced charging so as to ensure that
the charger can accurately monitor the voltage of each cell and balance the cells with poor
consistency. When charging in unbalanced mode (without connecting to the battery balance
port), the charger will have a warning before starting the task.
09 D6 Pro AC/DC Dual Channel Smart Charger
Charge Function
When charging is in progress, the screen is marked in orange, and the screen turns green or blue
when charging is completed. When the charging is completed, the cell voltage difference is less
than 20mV, and the screen turns green. If you need to use it urgently, you can stop charging it. If
charging is not stopped at this time, the charger will continue to balance the battery. When the
voltage difference is less than 10mV, the screen will turn blue. When turned blue, the charger will
continue to accurately balance the battery.
After having the battery charged, the voltage will drop back due to the difference in performance
and this is normal. As the number of charging increases, the performance of the battery gradual-
ly declines, such a phenomenon will become obvious. Charging with a larger charging current will
also cause the voltage to fall back after a full charge, which is more obvious.
Tips: If you are charging outdoors, and you want to finish it quickly, you can stop charging when
you see the appearance of green state. When there is enough time, and you hope that the battery
can achieve a good balance, ,then wait for the blue color to appear, or wait for a while more after
the blue appear to get more accurate effect.
Discharge Function
The discharge function can discharge the battery. It is recommended to connect the balance port
for discharge, which is faster and the detection on discharge termination is more accurate. Due
to The limitation of the internal discharge power , the discharge process may be slower, which is
normal.

Task Settings and Notes
Operation and Setup
External Discharge Function
The external discharge function uses the external high-power load resistor to quickly discharge
the battery accurately. When it is used, the battery to be discharged needs to be connected to the
input port, and the output is connected to the resister load. It is recommended that the resistance
of the load be between 1.5 and 2.5 ohms. Other resistance values can also be used normally, but
may not be able to operate at full power. When the external discharge is running, the load is very
hot. Please pay attention to safety and avoid accidents or personal injury.
10 D6 Pro AC/DC Dual Channel Smart Charger
Storage Function
When the storage function is selected, if the battery is lower than the preset storage voltage, the
charging task will be automatically performed; if the battery voltage is higher than the preset
storage voltage, the discharge task will be automatically performed. In order to save the task time,
the storage and discharge tasks do not accurately balance the cell voltage. There may be some
error between the cell voltage and the preset value at the end of the task, which is a normal
phenomenon.

Task Settings and Notes
Operation and Setup
11 D6 Pro AC/DC Dual Channel Smart Charger
Balance Function
The balance function is used to balance the voltage of cells and make them equal. The balance
time is related to the cell voltage difference and the target voltage. When the menu is switched
to the balance mode, the charger automatically analyzes and sets the initial balance voltage
value, and the user can freely adjust it. The charger's charging ability is much larger than the
discharge capacity; in the balance operation , selecting voltage equal or larger than the current
battery voltage usually lets you attain faster effect in balancing.
Battery Activation And Repair
After the charging task starts, if it is detected that the cell voltage is lower than the pre-charging
voltage, the cell will be activated and repaired using one tenth of the task setting current. After
the voltage becomes higher than the pre-charging voltage, the voltage will be adjusted to the set
voltage for charging. Such design can protect the over-discharged battery , activate and repair it.
About Internal Resistance Measurement
The D6 Pro AC/DC Dual Channel Smart Charger has a cell internal resistance measurement
function that is only effective when performing balanced charging tasks on the battery. About
two or three minutes after the start of the charging task, the internal resistance of the battery is
measured and calculated. The internal resistance of the battery varies with different power levels.
Generally speaking, the internal resistance measured is lower when the power is higher. When the
charger measures the internal resistance of the battery, the charging current is instantaneously
adjusted. Therefore, it is normal to find that the current is abruptly changed during the charging
process.
Due to the difference in the ways of measuring the internal resistance, the test accuracy of
internal resistance like those attained on professional measuring instruments cannot be
achieved. Therefore, the internal resistance value is only suitable for horizontal comparison
reference, such as judging the consistency of cell performance or comparing the performance
parameters of different batteries. The magnitude of the charging current has a certain influence
on the accuracy of the internal resistance measurement. A battery with a large capacity and low
internal resistance requires a large charging current to accurately measure the internal resistance.
