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.

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.

Discharge mode
When the working mode selects discharge, storage, and cycle mode, the battery setting interface will increase the discharge mode. As shown below.

Move the cursor to [Discharge Mode] and press [OK] to modify the discharge mode, as shown below.

M6D 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 from the discharging battery to the input battery, the maximum support is 15.0A@250W discharge.

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 witching 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.

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.
4. Glossary explanation:
   TVC: English abbreviation for terminal voltage control

Current setting
