4，Battery Setting
Move the cursor to the [Auto] or [xS] position
and press the [OK] button to change the number of
battery strings. Turn the [Code Plate] to adjust the
value. When set to [Auto], the charger will
automatically recognize the number of connected
batteries according to the battery voltage connected
to the output port.
=================================
Tip:
1, the battery is over-discharged or
over-charged, which may cause the
number of strings to be recognized. Error,
you need to manually set the correct
number of strings.
2, the number of strings is set incorrectly, may
not be full, or overcharged and damaged
the battery, please set it carefully.
3. After the Lixx battery is connected to the

@ToolkitRC 2018
14
balance port, the number of battery strings
can be more accurately identified.
=================================
5，Current setting
Move the cursor to the charging current [2.0A]
position and press [OK] to modify the charging
current. Turn [Code Plate] to adjust the value and
step 0.1A. Quickly rotate [code plate] to add or
subtract quickly. The charger supports up to
15.0A.
Move the cursor to the discharge current [2.0A]
position and press [OK] to modify the discharge
current. Turn [Code Plate] to adjust the value and
step 0.1A. Fast rotation [code plate] can be quickly
reduced. The charger supports two discharge
modes. 1, ordinary discharge mode, through internal
heat dissipation discharge, maximum support
3.0A@20W discharge. 2, recovery discharge mode,
when the input is battery power, through this

@ToolkitRC 2018
15
function to recover electrical energy to the input
battery, the maximum support 15.0A@300W
discharge
=================================
Tip:
1. Please set the charging rate of 1-2C
according to the battery capacity.
For example, if the battery capacity is
2000mAh, please set the charging current to
2.0-4.0A.
2, charging and discharging current is only
valid in the corresponding working mode
3. For the discharge mode setting, refer to the
<System Settings> chapter of this manual.
=================================

6，Working mode
Move the cursor to [Store] [Discharge] [Charge]
position, press [OK], the charger will work in the
mode of the selected function. When selected as
[Charge], it will indicate the target voltage that will
charge the battery. As shown below
When selected as [Discharge], it will prompt the
target voltage to put the battery. If the discharge
mode is to recover the discharge, it is also necessary
to set the cutoff voltage of the power battery. As
shown below
When selected as [Storage], it will prompt the

@ToolkitRC 2018
17
target voltage to charge and discharge the battery. If
the discharge mode is to recover the discharge, it is
also necessary to set the cutoff voltage of the power
battery. As shown below
The high limit voltage is recovered. The default is
0.5V higher than the input voltage. Please set
according to the maximum limit voltage of the input
power supply. To cancel the operation, move the
cursor [Cancel] or press [Exit]. Move the cursor to
[OK], short press [OK] to start charging, and display
the charging and discharging work interface.
=================================
Tip:
1. The discharge cutoff voltage should be set
according to the battery discharge
characteristics.
2. After the recovery limit voltage is set to the
highest protection voltage of the power
supply, the charger will automatically stop
the recovery discharge. Setting a high
overvoltage may damage the input power

When charging is complete or charging is wrong.
a prompt box pops up and a tone sounds.
=================================
1, when charging and discharging work,
please be guarded throughout the process,
in time to deal with abnormalities.
2. When charging and discharging the lithium
battery, only the main port will not be balanced.
Please pay attention to the balance of the battery.
After the balance port is connected, the balance
management is automatically performed.
3, charging is completed, unplug the battery, after
accessing the new battery, it will automatically
continue to charge and discharge according to the
set mode. When set to a fixed number of strings, you
need to access the same number of batteries. When
setting to automatically detect the number of
battery strings, please pay attention to whether the
number of detected strings matches the actual ones.
