After selecting the battery that matches the actual
battery. Short press [OK] and [Exit] to take effect and
return to the previous interface.
=================================================
Warning:
1. Choosing the wrong battery type to charge
may damage the battery, the charger, and cause burns,
etc. Please choose carefully.
2. Please do not use this product to charge the
battery that is not marked with the battery type.
===================================
Glossary of battery terms explanation:
1, Lipo: often referred to as a lithium polymer
battery with a nominal voltage of 3.70V and a fully
charged battery of 4.20V.
2, LiHV: often referred to as a high-voltage lithium
battery with a nominal voltage of 3.85V and a fully
charged battery of 4.35V.
3, LiFe: often referred to as iron-lithium battery, with a
nominal voltage of 3.30V and a fully charged battery of
3.60V.
4, Lion: often referred to as a lithium-ion battery with a
nominal voltage of 3.60V and a fully charged battery of
4.10V.

2. The Cells Setting
Move the cursor to the position of [Battery Section],
press [OK] to modify the cells of battery. The display is as
follows:
Rotate the [Scroll wheel] to adjust the value. When
set to [Auto], the charger will automatically identify the
number of strings connected to the battery according to
the battery voltage connected to the output port. Short
press [OK] and [Exit] to take effect and return to the
previous interface.
===================================
Tips:
1. The connected battery is over-discharged
or over-charged, which may cause incorrect
identification of the battery cells, so you need to
manually set the correct cells.

@ToolkiRC 2021
15
2. The Cells is set incorrectly, it may be
unsatisfactory, or overcharge may damage the battery,
please set it carefully.
3. After Lixx batteries are connected to the balance
port, the battery cells can be more accurately identified.
=================================
3. Work Mode
Move the cursor to [Mode] and press [OK] to
modify the work mode, as shown in the figure below:
Lipo, LiHV, LiFe, Lion batteries can be charged,
discharged, and stored. NiMh battery can choose to
charge, discharge, cycle. PB battery can choose to
charge and discharge. Short press [OK] and [Exit] to take
effect and return to the previous interface.

4. Discharge mode
When the working mode selects discharge, storage,
and cycle mode, the battery setting interface will
increase the discharge mode.
Move the cursor to [Discharge Mode] and press [OK]
to modify the discharge mode, as shown below:
The charger supports three discharge modes.
1. Normal mode: discharge through internal heat
consumption, maximum support 3.0A@10W discharge.
2. Recycle mode: when the input is battery power,
the power is recovered to the input battery through this
function, and the maximum support is 10.0A@200W
discharge.
3. External mode: when the input port is connected
to the discharge load and the output port is connected
to the battery, it can be discharged through this function,
and the maximum support 10.0A@200W discharge.

5. Input MaxVoltage
When the discharge mode is selected to recycle, the
battery setting interface will increase the input Max
Voltage setting. Move the cursor to [Input MaxVol] and
press [OK] to adjust the input Max voltage. If the input
voltage reaches this voltage value during discharge, the
discharge will stop. As shown below:
===================================
Tips:
Please set the input Max voltage to the highest
protection voltage of the power supply. After the voltage
is reached, the charger will automatically stop recycling
discharging. Setting high overvoltage may damage the
input power
===================================

6. End voltage setting (TVC)
Move the cursor to [End Voltage] and press [OK] to
modify the end voltage of the single-cell battery.
When the work mode is charge, it is the charge
cut-off voltage, and the range is plus or minus 50mV of
the full voltage. When the working mode is discharge, it
is the discharge cut-off voltage. Scroll [Scroll wheel] to
adjust the value, step 0.01V.
===================================
1. Only LiPo, LiHV, LiFe batteries can set the
cut-off voltage.
2. Do not modify the cut-off voltage when you are not
familiar with the battery characteristics.
3. The charging cut-off voltage can be set to a range of
plus or minus 50mV of full voltage.
4. Glossary explanation:
TVC: English abbreviation for terminal voltage control

7. Current setting
Move the cursor to the [Charge Current] or [DisCHG
Current] position, and press [OK] to modify the current.
Rotate [Scroll Wheel] to adjust the value, step by 0.1A.
Scroll [Scroll Wheel] quickly to increase or decrease. The
charger supports up to 10.0A.
=================================================
Tips:
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 charge current to
2.0-4.0A.
2. The charge and discharge current is only valid

When the battery type is NiMh, the negative
pressure value when the battery is fully charged can be
set, the range of which can be set is 5mV-15mV, as
shown below:
===================================
Tips:
1, Only NiMh battery can set negative battery
voltage.
