How to Conﬁrm Charging Current 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 an overheat even explosion during the charging process. The charging and discharging capacity of the 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.

Operating the Charger

Power on K2 smart charger, connect the battery, and short press the menu button to enter the task setting menu as follows:

Task	Charge, Discharge, Destroy, Storage
Battery	LiHv、LiPo、LiIon、LiFe、Pb、NiMh/Cd
Battery and cell count	LiFe,LiIon,LiPo,LiHv (1~6S) ; Pb (1~12S) ; NiMH/Cd

(1~16S)
Current| 0.2~20.0A

Charge
A 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 starting charging lipo if in non- balanced mode (no connecting with balance port). Current setting range: 0.2~20.0A The battery type, cell count and charging current are auto set accordingly when connecting with the BattGo battery.
Discharge
Current setting range: 0.2~1.5A
The battery type, cell count, and discharging current are auto-set accordingly when connecting with the BattGo battery.
Destroy
Connect the battery to be scrapped, and select the scrap function in task options, which is capable to discharge the battery to 0V. Current setting range: 0.2~1.5A; The battery type and cell count are auto-set accordingly when connecting with the BattGo battery.
Storage
Current setting range: 0.2~20.0A
The battery type, cell count, and storage current are auto-set accordingly when connecting with the BattGo battery.

Advanced Settings
Under the standby interface, long-press the CH1 and CH2 buttons at the same time to enter the advanced setting menu.
Dual-task
Select this setting,the charger will charge/discharge/store 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.

Parallel 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 ports. 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.

DC power (CH1)
The charger CH1 is equivalent to a DC power supply when selecting this function,
with output voltage adjustable from 2 to 30V, and current adjustable from 1.0 to 5.0A.

Under the advanced setting menu, select the system setting into the system setting menu as follows:
Min. input voltage protection: 10~31V
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 the battery pack as a power supply.

Max. input power setting: 100~1100W
If the input power is smaller than the max working power(1000W), 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.

USB Charge
When this item is set to “Oﬀ”, and TYPE-C is the upgrade port.
When this item is set to “On”, TYPE-C acts as a USB charging port and outputs 5V/2A power.

Split screen
There are 3 options of 60 seconds,30 seconds, and OFF for automatic split- screen settings. 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.
BattGo
When the corresponding channel (CH1 output, CH2 output, Power input) connects to a BattGo battery, you could read this and modify the related parameters of the Battgo battery.
Keep trickle
After charging is complete, choose whether to continue trickle charging.
The trickle charge function is enabled to maintain the lithium battery voltage in a fully charged state, this function is enabled by default.
Calibration:
The input voltage, output voltage, and balance voltage of the charger can be calibrated with this task.
