B8 also can monitor and balance individual cells of the Lithium battery pack during the discharge process. If the voltage of nay one cell varies abnormally, the process will be stopped with the error message.
Suitable for various types of Lithium batteries
B8 can accept three types of Lithium batteries-Lilo, 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. For their specifications, refer Warnings and safety notes Lithium battery
You can charge Lithium battery for special purposes. charge reduces the charging time of Lithium battery and mode controls the final voltage of the battery to be suit for long time storage.
Delta-Peak Sensitivity: The automatic charge termination program works on the principle of the Delta-peak voltage detection.
Auto-charge current limit: When charging NiCd or NiMH at you can set the upper limit of charge current to avoid from high current charging. This is very useful when charging the low impedance and small capacity NiMH battery in The charging capacity always calculated by multiple of the charging current and time. If the charging capacity exceeds the limit the process will be terminated automatically when you set the maximum value.
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 reached.
Processing Time Limit You can also restrain the maximum process time to prevent from any possible defect.

Reverse the sequence when disconnecting.
Very Important!
Do not connect more than one battery pack to the charge lead at any one time.
The charger is not suitable for the following battery types
Battery pack, which consists of different types of cell (including different manufactures) Battery which is already fully charged or just slightly discharged Non-rechargeable batteries (Explosion hazard).
Batteries that require a different charge technique from NiCd, NiMH, Lilo, LiPo, LiFe or Pb.
Faulty or damaged battery Battery fitted with an integral charge circuit or a protection circuit.
Batteries installed in a device, or which are electrically linked to other components.
Batteries that are not expressly stated by the manufacture to be suitable for the currents the charger delivers during the charge process.
Please bear in mind of checking the following point before
charge operation:

Did you select the appropriate program, which are suitable for the type of battery? Did you set up adequate current for charging or discharging? Lithium battery pack can be composed with parallel and series circuits mixed. You have to check the composition of the battery pack carefully before charging Are all connections firm and safe, or is there an intermittent contact at any point in the circuit? Charging
A specific quantity of electrical energy is fed into the battery during charge process. The charge quantity is calculated by multiplying charge current by charge time. The maximum permissible charge current varies according to the battery types or its performance, and can be found in the information provided by the battery manufacture. It is only allowed to charge batteries at rates higher then the standard charge current if they are expressly stated to be capable of quick-charge.
Connect the battery to charge to output terminal of the charger using suitable charge lead. They are red, positive (+) and black, negative (-). Since the charger cannot detect the difference between the internal resistances of the battery pack, cable resistance and connector transfer resistance, the first requirement if the charger to work properly is that the charge lead should be of adequate conductor cross-section. And also high-quality connectors (normally gold-contact type) must be fitted to both ends.
Refer to the information provided by the battery manufacture regarding charging methods, and verify the recommended charge current and charge time. Especially for Lithium batteries, you have to follow the charge instruction provided by the manufacturer strictly.
Do not attempt to disassemble the battery pack arbitrarily.
You have to pay attention to verify the capacity and the voltage of the Lithium battery pack. It may be composed of parallel and series connection mixed. In parallel link the capacity of the battery pack is multiplied by the number of cells but the voltage remains the same. That kind of voltage imbalance causes a fire or explosion during charge process. We recommend you compose the Lithium batter pack in series only.
Discharge
The typical purpose of discharge is to determine the residual capacity of the battery, or to lower the voltage of battery to a defined level. When you discharge the battery you also have to pay attention on the process same as charging. To avoid the battery becoming deep-charged, set the final discharge voltage correctly. Lithium batteries should not be deep-charged to lower than the minimum voltage, as this leads to a rapid loss of capacity or a total failure. Generally, you do not need to discharge Lithium battery voluntarily.
Some rechargeable batteries are said to have a memory effect. If they are partly used and recharged before the whole charge is drawn out, they time will only use that part of their capacity. This is a memory effect NiCd and NiMH batteries are said to suffer from memory effect. They prefer complete cycles; fully charge then use until empty, do not recharge before storage-allow them to self-discharge during storage. NiMH batteries have less memory effect than NiCd.
The Lithium battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided if possible. Instead, charge the battery more often or use a larger battery.
The brand-new NiCd battery pack is partially useful with its capacity until it has been subjected to 10 or more charge cycles in any case. The cyclic process of charge and discharge will lead to optimize the capacity of battery pack.
Those warning and safely notes are particularly important.
Please follow the instructions for a maximum safely; otherwise
the charger and the battery can be damaged violently. And also
it can cause a fire to injure a human body or to lose the property.

B8 will be operated with the default value of the essential user settings when it is connected to a 12V battery 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 start/enter
key to make it blink then change the value with Inc> or <Dec key. The value will be
stored by pressing start/enter key once.
This informs you of its designation.
The screen displays the nominal voltage of Lithium battery. There are three kinds of Lithium battery: LiFe(3.3V), Lilo(3.6V) or LiPo(3.7V). This is very important so you have to check the battery carefully and set it up correctly. If it is different from correct value the battery explode during charge process.
B8 recognize the cell count of Lithium battery automatically at the beginning of charge or discharge process to avoid from erroneous setting by user. But deeply discharged battery can be perceived incorrectly. To prevent the error, you can set the time term to verify the cell count by the processor. Normally, 10 minutes are enough to perceive the cell count correctly. For the battery of larger capacity, you may extend the time term. But if you set the time term to long for the battery of smaller capacity, the charge or discharge process can be finished within the time term with the erroneous cell count. This may cause the fatal result. If the processor recognizes the cell count incorrectly at the beginning of charge or discharge process, you may extend the time. Otherwise, you had better use with the default value.
This shows the trigger voltage for automatic charge termination of NiMH and NiCd battery. The effective value ranges from 5 to 20mV per cell. If the trigger voltage is set higher, there is a danger of overcharging the battery; if it is set lower, there is a possibility of premature termination. Please refer the technical specification of the battery. (NiCd default: 12mV, NiMH default: 7mV) An optional feature using temperature probe contacting the surface of battery, the temperature cut-off can be on or off. If it is on, set the maximum temperature at which the charger should allow battery to reach during charge. Once a battery reaches this temperature during charge, the process will be terminated to protect the battery. The battery is on the cyclic process of charge and discharge can often become warm after charge or discharge period. The program can insert a time delay to occur after each charge and discharge process to allow the battery adequate time to cool down before being subjected to the next process. The value ranges from 1 to 60 minutes.
You can set the trickle charge mode on or off. If it is on, the charger will automatically supply the trickle charge current to achieve the full charge without overheating the battery after fast charge has been terminated.
When you start a charge process, the integral safety timer automatically starts running at the same time. This is programmed to prevent overcharge the battery if it proves to be faulty, or if the termination circuit cannot detect the battery full. The value for the safety timer should be generous enough to allow a full charge of the battery.
This program sets the maximum charge capacity that will be supplied to the battery during charge. If the delta-peak voltage is not detected nor the safety timer expired by any reason, this feature will automatically stop the process at the selected capacity value.
The beep sounds at every time pressing the buttons to confirm your action. The beep or melody sounded at various times during operation to alert different mode changes. These audible sounds can be turned 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.
You can adjust the brightness of LCD screen at the charger.
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 that is termed a constant voltage (CV) and constant current (CC) method. The charge current varies according to the battery capacity and performance.
The final voltage of charge process is also very important; it should be precisely matched with the charade voltage of the battery. They are 4.2V for LiPo, 4.1V for Lilo, and 3.6V for LiFe. The charge current and nominal voltage as for cell count set on the charge program must always be correct for the battery to be charged.
When you are willing to alter the parameter value in the program, press start/enter key to make it blink then change the value with Inc> or <Dec key. The value will be stored by pressing start/enter key once.
