You get a rapid charger/discharger with integrated balancing circuit, which is computerised with a high performance microprocessor and specialised operating software. Please read this operating manual completely and attentively as it contains a wide variety of specific programming and safety information. You need to keep this manual in a safe place, and be sure to pass it on to the new owner if you ever dispose of BC8HP.
Temperature limit(*) : The temperature of the battery on charging will rise by its internal chemical reaction. If you set the limit of temperature the process will be expired forcibly when the limit has been reached. Processing time limit : You can also restrain the maximum processing time to prevent from any possible defect. Input power monitor : To protect the car battery using as input power from being damaged, its voltage always being monitored.
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 11 to 18V DC only. ! This charger and the battery to charge or discharge should be set up on a head-resistant, non-inflammable and non-conductive surface.
Pb 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). - Battery, which is already fully charged or just slightly discharged. - Non-rechargeable batteries (Explosion hazard).

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. When you are willing to alter the parameter value in the program, press ‘ENTER/START’ button to make it blinking, then change the value using ‘INC’ or ‘DEC’ button.
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. NiMH/NiCd D.Peak Delay time 15min Display DEC INC DEC + INC Temp.

The beep or melody sounded at various times during operation to alert different mode changes. These audible sounds can be on or off. This program monitors the voltage of input battery. If the voltage drops below the value you set the operation forcibly terminated to protect the input battery.
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. They are 4.2V for LiPo, 4.1V for LiIo, and 3.6V for LiFe.
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. And you should connect the battery output plug to the output of charger either.
'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. The charging capacity may be a bit smaller than normal charging but the process time will be reduced. LiPo[0] FAST CHG 2.0A 11.

The final voltage at the end of discharge is on the right according to the cell count and type of battery. For LiPo, it is 3.0V/cell. To start to discharge press ‘ENTER/START’ button for more than 3 seconds. (Discharge current: 0.1~7.
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.

You can use this function for balancing, refreshing and break-in the battery.
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. So the optimal charge current will be 1/10 of the capacity. Pb batteries must not be charged rapidly.
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. End Voltage 12.6V(3S) The final voltage will be reached at the end of process. Display DEC NiMH D.
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. REVERSE POLARITY The output is connected to a battery with incorrect polarity.
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'. So 2.0A is the same as 2000mA (2.0x1000). Or, to convert mA to amps, divide the mA number by 1000. So 200mA is the same as 0.2A. If a current value is below 1.0A, the LCD screen of the charger will still show the current in amps, not milli-amps.
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.
