  • Page 2: Special Features

    Thank you for purchasing the e-STATION 902. You get a rapid charger/discharger that is computerised with a high performance microprocessor and specialised operating software. It can maintain your battery at its best condition and also control them safely. Please read this entire operating manual completely and attentively as it contains a wide variety of specific programming and safety information.

  • Page 3: Exterior Of The Unit

    Temperature limit(**) : The temperature of the battery on charging will rise by its internal chemical reaction. If the temperature increases too much the charging process cannot be accomplished properly and also the battery can be damaged. If you set the limit of temperature the process will be expired forcibly.

  • Page 4: Warnings And Safety Notes

    Warnings and safety notes Never leave the charge unsupervised when it is connected to its power supply. If any malfunction is observed immediately terminate the process and refer to the operation manual. Keep away the unit from dust, damp, rain, heat direct sunshine and vibration. Do not drop it. The circuit of the unit is designed to be powered by a 12V DC only.

  • Page 8: Lithium Battery (Liio/Lipo/Life) Program

    Lithium battery (LiIo/LiPo/LiFe) program These programs are only suitable for charging and discharging Lithium batteries with a nominal voltage of 3.3V, 3.6V and 3.7V per cell. These batteries need to adopt different charge technique is termed a constant voltage(CV) and constant current(CC) method. The charge current varies according to the battery capacity and performance.
  • Page 9 'FAST' charging the Lithium battery The charging current is getting smaller as the process goes to the near end term of Lithium battery charging. To finish charging process earlier, this program eliminate certain term of CV process. Actually, the charging current will goes to 1/5 from the initial value to end the process while the normal charging goes to 1/10 during CV term.
  • Page 10 Discharging the Lithium battery The value of discharge current on the left side of screen LiPo Dischg may not exceed 1C for a maximum safety and the final 2.0A 11.1V(3S) voltage on the right should not be under the voltage level that is recommended by the battery manufacturer Display to avoid deep discharging.

  • Page 11: Nimh/Nicd Battery Program

    NiMH/NiCd battery program These programs are for charge and discharge of NiMH (Nickel-Metal-Hydride) or NiCd (Nickel-Cadmium) battery commonly used for R/C model applications. Please check the trigger voltages of each type of batteries for automatic charge termination at 'NiMH sensitivity' and 'NiCd sensitivity' on user setting program.

  • Page 13: Pb (Lead-Acid) Battery Program

    Pb (lead-acid) battery program This is programmed for charging Pb (lead-acid) battery with nominal voltage from 2 to 40V. Pb batteries are totally different from NiCd or NiMH batteries. They can only deliver relatively lower current compare to their capacity, and similar restrictions definitely apply to charge. So the optimal charge current will be 1/10 of the capacity.
  • Page 14 Charging at 'OUTPUT-2' / Electric motor drive This program can charge the battery at 'OUTPUT-2' regardless of operating 'OUTPUT-1'. At 'OUTPUT-2', you can charge NiCd or NiMH battery up to 8 cells with the maximum charge current of 2.0A. This program also employs the delta-peak voltage detection method to terminate charging process.
