To avoid short circuit between the charge lead always connect the charge cable to the charger first, then connect the battery. Reverse the sequence when disconnecting. Do not connect more than one battery pack to this charger at any one time. Never attempt to charge or discharge the following types of battery. A battery pack which consists of different types of cell (including different manufacturers) A battery that is already fully charged or just slightly discharged. Non-rechargeable batteries (Explosion hazard). Batteries that require a different charge technique from NiCd, NiMh, Li-Poly or Gel cell (Pb, Lead acid). A faulty or damaged battery. A 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 manufacturer to be suitable for the currents the charger delivers during the charge process.
Please bear in mind the following points before commencing charging:
Did you select the appropriate program suitable for the type of battery you will be charging? Did you set up adequate current for charging or discharging? Have you checked the battery voltage? Lithium battery packs can be wired in parallel and in series, i.e. a 2 cell pack can be 3.7V (in parallel) or 7.4V (in series). Have you checked that all connections are firm and secure? Make sure there are no intermittent contacts at any point in the circuit.
Do not attempt to disassemble the battery pack arbitrarily.

Charging

During charge process, a specific quantity of electrical energy is fed into the battery. The charge quantity is calculated by multiplying charge current by charge time. The maximum permissible charge current varies depending on the battery type or its performance, and can be found in the information by the battery manufacturer. Only batteries that are expressly stated to be capable of quick-charge are allowed to be charged at rates higher than the standard charge current. Connect the battery to the terminal of the charger: red is positive and black is negative. Due to the difference between resistance of cable and connector, the charger can not detect resistance of the battery pack, the essential requirement for the charger to work properly is that the charge lead should be of adequate conductor cross-section, and high quality connectors which are normally goldplated should be fitted to both ends Always refer to the manual by the battery manufacturer pertaining to charging methods, recommended charging current and charging time. Especially, the Lithium battery should be charged according the charging instruction provided by the manufacturer strictly. It should be paid attention to the connection of Lithium battery especially. Do not attempt to disassemble the battery pack arbitrarily Please get highlighted that Lithium battery packs can be wired in parallel and in series. In the parallel connection, the battery s capacity is calculated by multiplying single battery s capacity by the number of cells with total voltage stay the same. The voltage s imbalance may cause fire or explosion.Lithium battery is recommended to charge in series.

Discharging

The main purpose of discharging is to clean residual capacity of the battery, or to reduce the battery voltage to a defined level. The same attention should be paid to the discharging process as charging. The final discharge voltage should be set up correctly to avoid deep-discharging. Lithium battery can not be discharged to lower than the minimum voltage, or it will cause a rapid loss of capacity or a total failure. Generally, Lithium battery doesnt need to be discharged. Please pay attention to the minimum voltage of Lithium battery to protect the battery. Some rechargeable batteries have a memory effect. If they are partly used and recharged before the whole charge is accomplished, they remember this and will only use that part of their capacity next time. This is a memory effect It is said that NiCd and NiMH batteries are suffering from memory effect. NiCd has more memory effect than NiMH. Lithium batteries are recommended to be discharged partially rather than fully discharged. Frequent full discharging should be avoided if possible. Instead, charge the battery more often or use a battery of larger capacity. Full capacity cannot be used until it has been subjected to 10 or more charge cycles. The cyclic process of charge and discharge will optimize the capacity of battery pack.

As default this charger will be set to typical 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 parameter on each screen. If you need 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. The screen shows the nominal voltage of Lithium battery. There are three kinds of Lithium battery: LiFe(3.3V), Lilo(3.6V) or LiPo(3.7V). This information is of critical importance that you have to check the battery carefully to make sure it is set up correctly. If it is different from correct value, explosion can occur during charge process. To avoid from erroneous setting by users,iMax B6 detects the cell count of Lithium battery automatically at the beginning of charge or discharge process. But battery that is deep-discharged can't be detected correctly. To avoid this error, the time term can be set to verify the cell count by the processor. Normally, 15 seconds are enough to detect the cell count correctly. You need to extend the time term limit for the battery of large capacity. But the charge or discharge process may come to an end within the time term because of the time limit decided by the wrong count if you set too long time limit for the battery of small capacity. This may cause fatal error. You have to extend the time term if the processor detect the cell count incorrectly at the beginning of charge or discharge process. Otherwise, default value is recommended to use. This shows the trigger voltage for automatical charge termination of NiMH and NiCd battery. The valid value ranges from 5 to 20 mV per cell. Setting the trigger voltage higher brings a danger of overcharging; whereas setting it lower brings a possibility of premature termination. Please refer to the technical specification of the battery.(NiCd default:12mV, NiMH default:7mV)

To avoid short circuit between the charge lead always connect the charge cable to the charger first, then connect the battery. Reverse the sequence when disconnecting. Do not connect more than one battery pack to this charger at any one time. Never attempt to charge or discharge the following types of batteries.
A battery pack which consists of different types of cells (including different manufacturers) A battery that is already fully charged or just slightly discharged. Non-rechargeable batteries (Explosion hazard). Batteries that require a different charge technique from NiCd, NiMh, LiPo or Gel cell (Pb, Lead acid). A faulty or damaged battery. A 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 manufacturer to be suitable for the currents the charger delivers during the charge process.
Please bear in mind the following points before commencing charging:
Did you select the appropriate program suitable for the type of battery you are charging? Did you set up adequate current for charging or discharging? Have you checked the battery voltage? Lithium battery packs can be wired in parallel and in series, i.e. a 2 cell pack can be 3.7V (in parallel) or 7.4V (in series). Have you checked that all connections are firm and secure? Make sure there are no intermittent contacts at any point in the circuit. Charging
During charge process, a specific quantity of electrical energy is fed into the battery. The charge quantity is calculated by multiplying charge current by charge time. The maximum permissible charge current varies depending on the battery type or its performance, and can be found in the information by the battery manufacturer. Only batteries that are expressly stated to be capable of quick-charge are allowed to be charged at rates higher than the standard charge current. Connect the battery to the terminal of the charger: red is positive and black is negative. Due to the difference between resistance of cable and connector, the charger can not detect resistance of the battery pack, the essential requirement for the charger to work properly is that the charge lead should be of adequate conductor cross-section, and high quality connectors which are normally gold-plated should be fitted to both ends.

Always refer to the manual by the battery manufacturer pertaining to charging methods, recommended charging current and charging time. Especially, the Lithium battery should be charged according the charging instruction provided by the manufacturer strictly. Attention should be paid to the connection of Lithium battery especially. Do not attempt to disassemble the battery pack arbitrarily. Please get highlighted that Lithium battery packs can be wired in parallel and in series. In the parallel connection, the batterys capacity is calculated by multiplying single batterys capacity by the number of cells with total voltage stay the same. The voltages imbalance may cause fire or explosion.Lithium battery is recommended to charge in series.

Discharging

The main purpose of discharging is to clean residual capacity of the battery, or to reduce the battery voltage to a defined level. The same attention should be paid to the discharging process as charging. The final discharge voltage should be set up correctly to avoid deepdischarging. Lithium battery can not be discharged to lower than the minimum voltage, or it will cause a rapid loss of capacity or a total failure. Generally, Lithium battery doesnt need to be discharged. Please pay attention to the minimum voltage of Lithium battery to protect the battery. Some rechargeable batteries have a memory effect. If they are partly used and recharged before the whole charge is accomplished, they remember this and will only use that part of their capacity next time. This is a memory effect It is said that NiCd and NiMH batteries are suffering from memory effect. NiCd has more memory effect than NiMH. Lithium batteries are recommended to be discharged partially rather than fully discharged. Frequent full discharging should be avoided if possible. Instead, charge the battery more often or use a battery of larger capacity.Full capacity cannot be reached until it has been subjected to 10 or more charge cycles. The cyclic process of charge and discharge will optimize the capacity of battery pack.

PROGRAM FLOW CHART

INITIAL PARAMETER SETUP (USERS SET UP)
As default this charger will be set to typical user settings when it is connected to DC 11~18V for the first time. The screen displays the following information in sequence and the user can change the parameter on each screen. If you need 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. User setup starting screen. 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 may be exploded during charge process.

DEC INC

iMAX B6 PRO 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.

DEC INC DEC INC

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 becomes warm after cycles of charge/discharge process. The program will insert a time delay after each charge/discharge process to allow the battery enough time to cool down before beginning next cycle of charge/discharge process. The valid value ranges from 0 to 60 minutes.

- + INC

When the charge process starts, the integrated safety timer starts to run simultaneously. If error detected or the termination circuit can not detect whether the battery is fully charged or not, this unit is programmed to prevent overcharging. Please refer to the below statement to calculate the timer you set. Safe timer Calculation When charging NiCd or NiMH batteries, divide the capacity by current, then divide the result by 11.9, set this number of minutes as the value for safety timer setting. If the charger stopped at this time threshold, about 140% of the capacity will have been fed into the battery. For example: Capacity Current Safety Time 2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes 3300mAh 3.0A (3300/3.0=1100)/11.9=92 minutes 1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes
The program provides maximum capacity protection function. If the Deltapeak voltage can not be detected or the safety timer times out, the charge process will stop automatically, when the battery reaches the user-set maximum charge capacity, The beep to confirm users' operation sounds every time a button is pressed. The beep or melody sounds at various times during operation to confirm different mode change. These functions can be switched on or off. This function monitors the voltage of the input battery used to power this charger. If the voltage is lower than user-set value, the program will end forcibly to protect the input battery.
