  • Page 9 Usually, the NiCd battery voltage will drop a little right after reaching full NiCd Sensitivity charge. This is known as -△V.You can alter the charger’s delta-peak DeltaV Default detection sensitivity. Range: 1–20mV/Cell. (8mV/Cell,default) When NiMH &NiCd batteries are deeply discharged or left unused for a long time, they will produce a false-△V which stop charging early You can NiMH/NiCd Check disable-△V testing to avoid this problem.

  • Page 12: Lithium Battery Program

    Lithium battery programs The charger provides a number of Lithium programs including Balance, Normal, Fast and Storage. Only the Balance mode requires the balance lead connected. However, the other modes will provide additional per-cell over -voltage protection if the balance lead is connected compared to running them without it, where they can only utilize the total pack voltage.

  • Page 13: Charging Lithium Battery In Balance Mode

    Charging Lithium battery in BALANCE mode This function is for balancing the voltage of Lithium - polymer battery cells while charging.In the balance mode the battery balance lead must be connected to the balance port on the right side of the charger. The pinout of the balance port is shown in the diagram below.

  • Page 14: Charging A Lithium Battery In Normal Charge Mode

    Charging a Lithium battery in normal CHARGE mode The charger first charges with constant current (CC)according to the user set ting then constant voltage (CV) when the charging voltage reaches the peak point. In the CV phase the current gradually falls.The charger will terminate charging when the current falls below than 1/10 of the configured charge current.

  • Page 15: Pre-Charging A Lithium Battery

    Pre-charging a Lithium battery If the battery’s over-discharged and the voltage is too low then in the Normal charge or Fast charge modes the charger will notify the user of pre-charging with a low current (100mA).This helps to increase the battery voltage to the with in the allowable range for normal charging.

  • Page 16: Discharging A Lithium Battery

    Discharging a Lithium battery In this mode, you can set the target per-cell voltage and hence the final voltage (final voltage=cell voltage *number of cells). The lowest allowable cell voltage depends on the type of Lithium battery:2.50V for Lilo, 3.00V for LiPo and 2.00V for LiFe per cell. If the battery is connected to the balance port, the charger can monitor the individual cell voltages.

  • Page 17: Lithium Battery External Expanding Discharge Mode

    Lithium battery external expanding discharge mode You can expand the charger’s discharge power capacity by connecting the external capacity resistance. What should pay special attention is that, when expanding discharge, the balance port must connect to the battery and the expanding capacity resistance R should be series connected to the positive pole(See in the following diagram) Lixx Batt.
