Battery charging modeThere are five charging modes in this charger.
Charge the battery.
When charging a multi-cell battery, also connect the battery's balanced charging connector to the charger.
The battery will then be charged while balancing each cell.
If the balanced charging connector is not connected, you will hear a beep.
You can specify 0.1 to 8.0A for the charging current.
For an explanation of "cell" and "balance" of battery, see Drone Battery Knowledge / How to long-lasting and reviving .
Discharges an overcharged battery for long-term storage.
You can specify 0.1 to 1.0A for the discharge current.
|You can use the charger as a DC power supply. It can be used as a power supply to output any voltage and current. You can specify 2.0 to 30.0V for output voltage and 0.2 to 5.0A for output current. However, be careful not to specify output power that exceeds the capacity of input power supply.
Charges or discharges the battery for long-term storage.
Battery will be charged or discharged until it reaches the target voltage ("Storage voltage" column in the table below).
For explanation of long-term battery storage, see Drone Battery Knowledge / How to long-lasting and reviving .
Completely discharge to dispose of the battery when it is no longer needed.
Battery will be discharged until the voltage reaches 0V.
You can specify 0.1 to 1.0A for the discharge current.

Connection with battery
The AC adapter used this time is Anker 521 Charger (output 40W) . I also tried Anker Nano II 65W (output 65W) , but couldn't activate the charger.
The connector for balanced charging has a negative pole on the far left. Insert the connector so that the negative battery cable (usually black) matches the leftmost pin.
If you don't have a cable that fits your battery, you'll have to prepare it yourself.

How to calculate charge currentMaximum charge current that can be passed from charger to battery is calculated from the battery capacity (mAh) and the charge / discharge capacity (C) of the battery. For example, a battery labeled "2S-300mAh, 30C/60C" can carry a maximum charge current of 0.3 (A) x 30 (C) = 9 (A). And in this case, it takes about 1/30 hours (= 2 minutes) to fully charge. Be sure to charge below this maximum current.
Also, when powering charger from AC adapter, pay attention to the maximum output of connected AC adapter. Charge with smaller of the maximum output current of AC adapter and the maximum charging current of battery.
However, if you charge with the maximum current, battery will heat up and deteriorate. It is recommended to charge with a sufficiently lower current with a margin. It depends on the C value of the battery, but it is safe to charge at around 1-2A at most.
Note: When charging a battery with unknown C value, set charging current of charger assuming C value of 1 or less to avoid dangers such as ignition. For example, when charging a 300mAh battery with an unknown C value, set the charging current to 0.3A or less. In this case, it will take about 1 hour to charge.

Basics of operation method
All you need to do is one button at the bottom of the display. Press the top of the button to scroll the screen up. Press the bottom of the button to scroll down the screen. Press the center of the button to "OK" the selected item.
However, pressing the center of the button is difficult and can scroll up and down.
Before you start using, press and hold the center of the button to check or change the system settings of the charger . In particular, set "Lowest Input Voltage" and "Max Input Power" accurately.
Press the top or bottom of the button to select a menu, then press the center of the button to "OK". The following items can be checked and set.
|Specify the charging mode. You can choose from Charge, Discharge, Strage, DC Power, and Destroy.
|Specify the battery type. You can choose from LiHv, LiPo, LiIon, LiFe, Pb, NiHM / Cd.
Specify the charging target voltage for each cell.
For LiPo batteries, 4.10 to 4.30V can be set in 0.01V increments.
Note: Do not change this value from the specified value (the value in "Full charge voltage" column of "Charging Parameters" table above) unless you have a specific reason to do so. Otherwise, the battery will be overcharged and may overheat or ignite.
|Specifies the number of battery cells to charge. This value is automatically determined by the charger. If the judgment value is incorrect, check that balance charging cable is not broken and then set it manually. For LiPo battery, 1 ~ 6S can be set.
|Specify the charging current. You can set 0.1 to 8.0A in 0.1A units. Set an appropriate value according to the calculation method of charging current . Otherwise, power supply, battery or charger may generate heat or ignite.
|Charging will start.
|Return to startup screen.
End of charging
When installing / removing the battery, be careful not to accidentally touch the connectors and short-circuit them. If you do not continue to charge another battery, it is safe to unplug the charger before removing the battery.
Check / change system setting values
|Lowest Input Voltage
|When the input voltage drops below this value, all tasks are aborted and a warning is displayed. When using a battery for the input power supply, set it to avoid over-discharging the input battery. 10.0 to 24.0V can be set in 1.0V increments.
|Max Input Power
|Specifies the maximum power of input power supply. Set a value less than input power supply. Be sure to set this value when the output of the power supply used is lower than 230W. Otherwise, the power supply may be overloaded and charging may become unstable. 50 ~ 230W can be set in 10W increments.
|Specifies the brightness of the backlight. You can choose from Low, Middle, and High.
|Specify the volume of the operation sound and warning sound. You can hear warning sound even if you turn this Off. You can choose from Off, Low, Middle, High.
|Specify how to sound the notification sound when charging is completed. You can choose from Single and Repeat.
|Specify the menu display language. You can choose from English, Chinese (simplified / traditional), Japanese, German, French, and Spanish.
|Specify whether to perform trickle charging after charging is completed. You can choose from Off and On.
|Perform a self-diagnosis of the charger. The test will be completed in a few seconds. If there is no problem, "All test passed!" Will be displayed at the end.
|Calibrate the charger. You can adjust the input voltage, output voltage, and measured value of each cell voltage. If you connect battery to the charger and then select this menu, voltage of each cell will be displayed on the screen. You can adjust the value by selecting each item and pressing the center button. Finally, select "Save" menu to save the adjustment values.
|Displays system information (version) of the charger.
|Return to startup screen.
How to update the firmwareiSDT chargers can update the firmware (built-in basic software). Updating will fix bugs or add new features.
Note: Never run untrusted exe files. Do not run anything other than programs downloaded directly from iSDT official site. Otherwise, it may be contaminated with viruses etc.
There are two types of USB cables: "For data communication" where all terminals are connected, and "For charging" where only power supply terminals are connected. You need to use "For data communication" to make the computer recognize the charger. Please note that some cables attached to bonus of mobile phone or charger, battery are "For charging".
You can check for the latest version by clicking "Check for updates". If there is the latest version, "Please click Update!" will be displayed. If the update is not required, "The device is already the latest firmware." is displayed.
Click "Update" to update.
