• PB: Lead-acid battery, nominal voltage 2.00V.

2. Number of Cells

Move the cursor to [Battery cell Number] and press [OK] to modify the number of battery cells. The display shows options like 1S, 2S, 3S, 4S, 5S. Turn [Scroll wheel] to adjust. When set to [Auto], the charger automatically recognizes the number of connected battery cells based on voltage. Short press [OK] and [Exit] to save.

Tips:

• Over-discharging or over-charging can lead to incorrect cell number recognition; manual setting may be necessary.
• Incorrect cell number setting may result in incomplete charging or battery damage. Set carefully.
• After connecting a Lixx battery to the balance port, the number of battery cells can be identified more accurately.

3. Mode

Move the cursor to [Mode] and press [OK] to modify the working mode. Options include Charge, DisCHG, StoCHG.

Lipo, LiHV, LiFe, Lion batteries can be charged, discharged, and stored. NiMh battery can choose charge, discharge, cycle. PB battery can choose charge and discharge. Short press [OK] and [Exit] to save.

4. Discharge Mode

When discharge, storage, or cycle mode is selected, the battery setting interface will show discharge mode options. Options include 'Inter' (Internal) and 'Recycle'.

• Recycle mode: Recovers electric energy from the discharging battery to the input battery (if suitable), maximum support 15.0A@250W discharge.

5. Input MaxVoltage

When 'Recycle' mode is selected, the input MaxVol setting becomes available. If the input voltage reaches this setting during discharge, the discharge will stop.

Tip: Please set the input cut-off voltage within the safe voltage range of the power supply. 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. This is the charging cut-off voltage when charging, or discharge cut-off voltage when discharging. The range is +/- 50mV of the full voltage. Adjust in steps of 0.01V.

Tips:

• Only LiPo, LiHV, LiFe batteries can set the end voltage.
• If unfamiliar with battery characteristics, do not modify the cut-off voltage.
• The charging cut-off voltage can be set to a range of plus or minus 50mV of full voltage.
• Glossary: TVC is the English abbreviation for terminal voltage control.
