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 the risk of
burning, so please choose carefully.
2，Do not use this product to charge batteries that do
not indicate the battery type.
=================================
Glossary of battery terms explanation
1, Lipo: often referred to as a lithium polymer

@ ToolkitRC 2021
13
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.
5, NiMh: often called NiMH battery, nominal voltage
1.20V.
6, PB: often called lead-acid battery, nominal voltage
2.00V.
=================================
2，Number of cells
Move the cursor to the position of [Battery cell
Number] and press [OK] to modify the number of
battery cells. The display is as follows.

@ ToolkitRC 2021

Turn [Scroll wheel] to adjust the value. When set to
[Auto], the charger will automatically recognize the
number of connected battery cells 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，Over-discharging or over-charging of the
connected battery may lead to incorrect recognition of
the battery cell number, and it is necessary to manually
set the correct cell number.
2，If the cell number is set incorrectly, it may not
be fully charged, or the battery may be damaged by
overcharging. Please set it carefully.
3，After Lixx battery is connected to the balance

port, the number of battery cells can be more accurately
identified.
===================================
3，Mode
Move the cursor to [Mode] and press [OK] to
modify the working mode, as shown 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. As shown below.

@ ToolkitRC 2021
16
Move the cursor to [Discharge Mode] and press [OK]
to modify the discharge mode, as shown below.
M6DAC supports two discharge modes.
1. Inter (Internal) Mode, discharge through internal
heat consumption, maximum support 3.0A@12W
discharge.
2. Recycle mode, when the input is a suitable
battery, this function can recover the electric energy

@ ToolkitRC 2021

from the discharging battery to the input battery, the
maximum support is 15.0A@250W discharge.
5，Input MaxVoltage
When the discharge mode is selected to recycle, the
battery setting interface will increase the input MaxVol
setting. As shown below.
Move the cursor to [Discharge Mode] and press [OK]
to adjust the input MaxVol. If the input voltage reaches
this voltage during discharge, the discharge will stop.
=================================
Tips：
Please set the input cut-off voltage withing the
safe voltage range of the power supply battery. After the
voltage is reached, the charger will automatically stop
recycling and discharging. Setting a high over-voltage
may damage the input power battery.

6，End voltage（TVC）
Move the cursor to [End Voltage] and press [OK] to
modify the end voltage of the single battery. When the
working mode is charging, it is the charging 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 the [Scroll Wheel] to
adjust the value in steps of 0.01V.
=================================
1，Only LiPo, LiHV, LiFe batteries can set the end
voltage.
2 ， If not familiar with battery characteristics,
please do not modify the cut-off voltage.
3，The charging cut-off voltage can be set to a
range of plus or minus 50mV of full voltage.
