In the main interface, select and short press the [Scroll
wheel] to enter the charging function, open the battery
selection option in system settings, and the following
interface will be displayed.
1. Battery type setting
Scroll the [Scroll Wheel], and select one of the

can be created. Short press the [Scroll Wheel] to enter a
specific battery setting, the display is as follows:

@ToolkiRC 2023
10
Move the cursor to [Battery Type] and Short press
the [Scroll Wheel] to modify the battery type, the display
is as follows:
The charger supports charging and discharging of 6
types of batteries: Lipo, LiHV, LiFe, Lion, LTO, NiMh, and

@ToolkiRC 2023
11
PB. There is also a smart battery mode to choose from.
After selecting the battery type that matches the battery
on charge, short press the [Scroll Wheel] and [Exit] to
save and return to the main interface.
=================================================
Warning:
1. Ensure the correct battery type has been
selected prior to charging. An incorrect choice may
damage the battery and/or become a fire hazard.
Please with caution.
2. Do not use this product to charge non-compatible
battery chemistries.
===================================
===================================
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

@ToolkiRC 2023
12
nominal voltage of 3.60V and a fully charged battery of
4.10V.
5, LTO : often referred to as a lithium-ion battery with a
nominal voltage of 2.40V and a fully charged battery of
2.70V.
6, NiMh: often called NiMH battery, nominal voltage
1.20V.
7, PB: often called lead-acid battery, nominal voltage
2.00V.
==================================================
2. Cell Setting
Move the cursor to [Battery Section], then short
press the [Scroll Wheel] to modify the number of cells.
The display is as follows:
Rotate the [Scroll wheel] to adjust the value. When

@ToolkiRC 2023
13
set to [Auto], the charger will automatically identify the
number of cells by checking the total voltage against the
balance port data. Short press the [Scroll Wheel] and
[Exit] to take effect and return to the previous interface.
===================================
Tips:
1. If the connected battery is over-discharged
or over-charged, this may cause an incorrect
cell-count, in which case the cell number needs to
be adjusted normally.
2. If the cell count is set incorrectly, it may lead to
overcharging, which can present itself as a fire risk.
3. The cell count can be more accurately
determined if the balance port is connected.
=================================
3. Work Mode
Move the cursor to [Mode] and short press the
[Scroll Wheel] to modify the work mode, as shown in the
figure below:

@ToolkiRC 2023
14
Lipo, LiHV, LiFe, Lion, LTO batteries can be charged,
discharged, and stored. NiMh battery can be charged,
discharged, or cycled. PB battery can be charged and
discharged. Short press the [Scroll Wheel] and [Exit] to
take effect and return to the previous interface.
4. Discharge mode
Under discharge, storage, and cycle modes, the
option of discharging the battery will appear.
Move the cursor to [Discharge Mode] and short
press the [Scroll Wheel] to modify the discharge mode,
as shown below:

@ToolkiRC 2023
15
The charger supports three discharge modes.
1. Normal mode: discharge using internal heat
dissipation, maximum 3.0A@20W discharge.
2. Recycle mode: when a battery is used as the
input, the power is recovered to the input battery
through this function, max 20.0A@600W discharge.
3. External mode: when the input port is connected
to a discharge load and the output port is connected to
the battery, it can be discharged through this function.
Max 20.0A@600W discharge.
5. Max input voltage
When the discharge mode is selected to recycle, the
Max input voltage option will appear. Move the cursor to
[Max Input Vol.] and short press the [Scroll Wheel] to
adjust. If the input voltage reaches this voltage value

@ToolkiRC 2023
16
during discharge, the discharge will stop. As shown
below:
===================================
Tips:
Please set the Max input 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 short press
the [Scroll Wheel] to modify the end voltage for the
individual cells.
When charging, it is the charge cut-off voltage, and
the range is plus or minus 50mV of the full voltage.

@ToolkiRC 2023
17
When discharging, 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 if 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. Nomenclature:
TVC: English abbreviation for terminal voltage control
=================================================
7. Current setting
Move the cursor to the [Charge Current] or [DisCHG
Current] position, and short press the [Scroll Wheel] to

@ToolkiRC 2023
18
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 /discharge current is only valid in
the corresponding work mode.
3. For the discharge mode setting, please refer to
the <System Settings> chapter of this manual.
==================================================
8. NiMH setting (PeakV)
When the battery type is NiMH, the peak voltage
value when the battery is fully charged can be set, the

@ToolkiRC 2023
19
range of which can be set is 5mV-15mV, as shown below:
===================================
Tips:1, This function is only available on NiMH
cells
PeakV: The maximum voltage drop per cell, when the
nickel-metal hydride battery is fully charged
===================================
9. Cycle setting
When the battery type is NiMh, and under cycle
mode, the option of Cycle time and Rest time will appear,
as shown below:

@ToolkiRC 2023
20
Move the cursor to [Cycle times] and short press
the [Scroll Wheel] to set the range of cycle times to 2-12.
The charger will follow the pattern:
discharge->charge->discharge->charge....
"Discharge -> charge" is 2 times.
