Never use the charger without supervision, please stop using the charger and refer to the manual for reasons if any functional abnormity.
Keep the charger away from dust, humidity, rain and high temperature, as well as avoid direct exposure to the sunlight and intense
vibration.
Place the charger on a heat-resisting, non-flammable and insulating surface. Do not use it on the car’s seats, carpet or other similar
places. Keep inflammable and explosive objects away from operation areas of the charger.
Read the instruction manual carefully to be familiar with the features of the charger, and set proper charging parameters before
operating. Setting the parameters incorrectly will result in damage to the product, personal property and cause serious injury as well.

Make sure to know the maximum charging current of the battery before charging, never use excessive current to charge to damage
your battery, which will result in over heat even explosion 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 supported
by the battery. For example, for a 1000mAh 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 (e.g. it needs around 60~70 minutes to complete charging with 1C).
Due to differences in battery conversion efficiency, the time to complete the charging might be extended.
How to Confirm Charging Current
Power on K1 smart charger, connect the battery, and short press the middle button to enter the task setting menu as follows:

Charge
Balancing port is strongly recommended when charging lipo battery, which can make sure to monitor voltage on each cell battery and
balance it when charging. Warning beeper will yell before start charging lipo if in non-balance mode(no connecting with balance port).
Current setting range: 0.2~10.0A
Charging Screen
Press the direction button to switch the information displayed in the lower half of the screen, as cell voltage, cell internal resistance,
working parameter. The cell voltage and internal resistance only on display in balancing charging mode.
Under the standby interface,
long press the left and right channel selection buttons at the same time to enter the advanced settings menu.
Advanced Settings
Dual task
Select this setting,the charger will charge to the two channel batteries with the same parameters at the same time.
Connect the charger with the power supply and power on, select this setting on the advanced setting menu to set the task parameters.
DC power (CH1)
The charger CH1 is equivalent to a DC power supply when
selecting this function, with output voltage adjustable from
5~24V, and current adjustable from 0.2~5.0A.
Paralled task
Select this setting, it could output Max Power to one battery.
Find a power splitter or 1/2 power cord, one end connect
with the battery, and the other two ends connect with
the battery output port. The battery balance port could
connect with any of the charger's balance port. Connect
the charger with the power supply and power on, and connect
your battery as required, select this setting on the advanced
setting menu to set the task parameters. Paralled charge

Under the advanced setting menu, select the system setting into the system setting menu as follows:
System Setting Menu
Min. input voltage protection: 10~24V
all tasks in operation will be stopped at once and hint warning of low voltage, when the input voltage is lower than the input voltage
as set up. It will protect the battery from being discharged when using battery pack as power supply.
Max. input power setting: 100~550W
if the input power is smaller than the max working power (550W) , please set up the parameter as the actual output power as max input,
to protect the input power and enable the charger to work stable.
Volume
There are 4 options of High Mid Low and Off for volume setting.When the setting is OFF,
it will turn off the operation sound,but not the warning error beep.
Split screen
There are 3 options of 60 seconds,30 seconds and OFF for automatic split screen setting.
You can choose to switch the display of the main interface from the single-channel parameter interface to
Dual channel (split screen) parameter interface. You can also select "Off" to turn off the automatic split screen function.
Self-test
When all batteries on CH1 and CH2 port are not connected, please select this option to self-test task manually.
Calibration
the input voltage, output voltage and balance voltage of the charger can be calibrated with this task.
