  • Page 2: Special Features

    - Accept various types of Lithium battery BC8HP can accept three types of Lithium batteries - LiIo, LiPo and LiFe. They have different characteristics by their chemistry. You can select any one of them that you are going to process before the job.

  • Page 3: Exterior Of The Unit

    - PC based analysis using USB communication(**) For technical expert, BC8HP offers PC based program can analysis the characteristic of the battery by USB port. It shows a graph of voltage, current, capacity and temperature curves. It also shows the individual voltage of each cell in the Lithium battery pack.

  • 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.
  • Page 5 voltage level: 2.0V/cell (Lead-acid) max. charge voltage: 2.46V/cell allowable fast charge current: 0.4C or less discharge voltage cut off level: 1.75V/cell or higher Do not attempt to charge or discharge the following types of battery. - Battery pack, which consists of different types of cell (including different manufacturers).

  • Page 7 Initial parameters setup (User Program Setup) BC8HP will be operated with the default value of the essential user settings when it is connected to a 12V DC input power source for the first time. The screen displays the following information in sequence and the user can change the value of parameter on each screen.
  • Page 8 Default; If you do not know much about this function, or for ordinary batteries, select this mode. 12mV/cell for NiCd or 8mV/cell for NiMH will be used. This restrains the delta-peak voltage detection until NiMH/NiCd D.Peak the time has reached. This prevents a premature Delay time 15min cut-off from the battery of high internal resistance.

  • Page 9: Program Memory

    100% Display Program Memory BC8HP can store the setting data of every program for your convenience. This feature can store up to 10 battery data for each type of batteries by number that represents the individual parameters. They can be called back for the process of charging or discharging without setting up the program again.

  • Page 10: 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(LiFe), 3.6V(LiIo) and 3.7V(LiPo) per cell. The final voltage of charge process is very important; it should be precisely matched with the charged voltage of the battery.
  • Page 11 Charging Lithium battery at balance mode This is for balancing the voltages of Lithium batteries of the battery pack to be charged. To do this, the battery pack being charged should have the individual cell connector, and connect it to the individual port at the right side of charger with a suitable connection cable that fits with your battery pack.

  • Page 12: 'Fast' Charging Lithium Battery

    'FAST' charging 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 at end of CV term.

  • Page 13: Discharging Lithium Battery

    If the voltage of any one or more cells varies abnormally during discharge, BC8HP terminates the process forcibly with the error message. If this happens, the battery pack contains a bad cell, or bad connection of the cable or plug.

  • Page 14: Nimh/Nicd Battery Program

    NiMH/NiCd battery program These programs are for charging or discharging NiMH (Nickel-Metal-Hydride) or NiCd (Nickel-Cadmium) battery commonly used for R/C model applications. Charging NiCd/NiMH battery This program simply charges the battery using the NiMH[0] CHARGE A current you set. You can select charge current mode in CUR LIMIT 5.0A ‘A’(automatic) or ‘M’(manual).

You can use this function for DCHG>CHG balancing, refreshing and break-in the battery. To Display avoid rising temperature of the battery, there will a brief cool-off period that already fixed at 'User program setup' after each charge and discharge TYPE...

  • Page 16: Pb (Lead-Sulphuric Acid) Battery Program

    Pb (lead-sulphuric acid) battery program This is programmed for charging and discharging Pb (lead-acid) battery of nominal voltage from 2 to 36V. 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.

  • Page 17: Various Information During The Process

    Various information during the process You can inquire various information on LCD screen during charging or discharging process. When you press ‘DEC’ button the charger shows the establishment of user settings. And also you can monitor the voltage of individual cell by pressing ‘INC’ button when the individual connection cable is linked to the Lithium battery being processed.

  • Page 18: Warning And Error Messages

    Warning and error messages BC8HP incorporates a various functions of protective and monitoring the system to verify functions and the state of its electronics. In any case of occurring error, the screen displays the cause of error that is self-explanatory with audible sound.

  • Page 19: Glossary Of Terms

    Glossary of terms Amps(A): The unit of measure for charge or discharge electric current. The program of the charger will show most of the current in amps(A) at its LCD screen. Milli-amps(mA): The electric current, being amps(A) multiplied by 1000 and noted as 'mA'.
  • Page 20 Balancing the multi Lithium battery packs You can charge and balance several Lithium batteries at the same time, by using optional ‘Multi-board adaptor’(*). Please note that the battery packs being charged should have same capacity and cell-count. * Part no. EAC153, EAC154, EAC158 and EAC159. Please read the instructions come with the board for the maximum safety.
