  • Page 6 Carefully follow the battery pack manufacturer‘s recommendations and safety advice. Recommended connecting way: 1. Connect iCharger's input power supply, and turn on it. 2. Connect Li batteries' balance port 3. Connect the main charging port's positive pole to cells' positive pole, and then connect negative pole to cells' negative pole (this will avoid striking fire while connecting Li cells).

  • Page 13 208B Lithium battery program The iCharger 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 14 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 iCharger. The pinout of the balance port is shown in the diagram below. Charging in this mode is different from the normal CHARGE mode because the iCharger can monitor the voltage of individual cells and adjust the input current fed into each cell to normalize the voltage (for example: LiPo battery within 4.2V).
  • Page 15 The iCharger first charges with constant current (CC) according to the user setting then constant voltage (CV) when the charging voltage reaches the peak point. In the CV phase the current gradually falls. The iCharger will terminate charging when the current falls below than 1/10 of the configured charge current.
  • Page 16 If the battery is over-discharged and the voltage is too low then in the Normal charge or Fast charge modes the iCharger will notify the user of pre-charging with a low current (100mA). This helps to increase the battery voltage to the within the allowable range for normal charging. The user can set the pre-charging time in the Lithium Check time screen in the User setup.
  • Page 17 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 iCharger can monitor the individual cell voltages. The discharge will stop immediately if any cell falls below the configured final voltage.
  • Page 18 Series In this mode, the lithium battery discharges through iCharger and R, P = Pi + Pr, (Pi is charger‘s wasted power capacity; Pr is wasted power capacity by resistance). Pi is limited by the set charger‘s maximum discharge power capacity（<30W） . But in the first 30 seconds of discharge startup, Pi can be reached 150W.
  • Page 19 Series Lithium battery in monitoring mode When you use other devices to charge or discharge Lithium pack, the iCharger can monitor each cell‘s voltage, battery temperature, charge time and so on, if one of the batteries appears over-charged, over-discharged, over-hot, over-capacity or over-time ,the iCharger will alarm with noise “Di…..” and blink the raleted information.
  • Page 20 The left side of the first line displays the type of battery (NiCd/NiMH) and the NiMH CHARGE Aut second line allows you to set the current limit. The iCharger offers two charging modes for NiCd/NiMH., ‗CHARGE Aut‘ and ‗CHARGE Manual‘. In 1.0A...
  • Page 21 This forming charge program aims to eliminate capacity imbalance between cells in a battery. The iCharger first charges with constant current (CC=1C) according to the user setting. When the charging voltage reaches the peak threshold (1.48V/cell) it switches to the CV phase. In the CV phase the current gradually falls.

    Note: iCharger 208B can support Pb (lead-acid) foaming charge. First, you should start the setting of ―Trickle‖ in ―NiMH/NiCd/PbTrickle‖. It won‘t foam charge until the voltage is less than 2.25V/cell. Discharging a Pb battery Discharging Pb battery. The left side of the first line shows the type of Pb DISCHARGE battery(Pb).
  • Page 23 You can easily break-in new brushed electric motors using a variable voltage and running time. Note that the iCharger cannot directly drive brushless DC motors and that brushless motors do require or benefit from a breaking-in process. With this function you also check the motor performance to optimize your power-train.
  • Page 24 The lower the resistance, the less restriction the battery encounters in delivering the needed power spikes. The iCharger can not only measure the internal resistance of the battery pack, and also can measure the per-cell internal resistance（only available for lithium battery）.
  • Page 25 208B Data save/load program The iCharger has a storage and load program for your convenience. This feature can store up to 10 battery datasets by number. Each dataset represent your settings for a particular set of batteries. Datasets can be reloaded for charging or discharging to save having to re-enter all the parameter values again by hand.
  • Page 26 208B Log Files Management iCharger 208B has a 16Mbit flash storage, which can log offline charge and discharge data in 36 hours. The users can transfer these data to logview for analyzing and plotting when it is necessary. Log files management.
