WARNING AND SAFETY NOTES
To avoid short circuit between the charge lead always connect the charge cable to thecharger 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, LiPoor 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 othercomponents.
Batteries that are not expressly stated by the manufacturer to be suitable
for the currents the charger delivers during the charge process.

07

WARNING AND SAFETY NOTES
Please bear in mind the following points before commencing charging:

“
“
“
“

Did you select the appropriate program suitable for the type of battery you arecharging?
Did you set up adequate current for charging or discharging?
Have you checked the battery voltage? Lithium battery packs can be wired inparallel and in series, i.e. a 2 cell pack can be 3.7V (in parallel) or 7.4V (inseries).
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 canbe 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 thestandard charge current.
Connect the battery to the terminal of the charger: red is positive and black is negative. Due tothe 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 isthat 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.

08

WARNING AND SAFETY NOTES
Always refer to the manual by the battery manufacturer pertaining to charging methods,
recommended charging current and charging time. Especially, the Lithium battery should becharged 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 theparallel 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 thebattery’ 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 willcause a rapid loss of capacity or a total failure. Generally, Lithium battery doesn’t need to bedischarged. Please pay attention to the minimum voltage of Lithium battery to protect thebattery.
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 oftheir 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 thecapacity of battery pack.

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 forthe 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 blinkthen change the value with INC or DEC key. The value will be stored by pressing
Start/Enter key once.
User setup starting screen.

INC

The screen displays the nominal voltage of Lithium battery. There are threekinds 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.

iMAX B6 PRO recognize the cell count of Lithium battery automatically at the
beginning of charge or discharge process to avoid from erroneous setting byuser. But deeply discharged battery can be perceived incorrectly. To preventthe 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 thebattery of larger capacity, you may extend the time term. But if you set the timeterm 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 atthe beginning of charge or discharge process, you may extend the time.
Otherwise, you had better use with the default value.

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, thendivide 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 thecapacity 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 is only suitable for charging/discharging Lithium(LiPo/LiIo/LiFe) batteries with anominal voltage of 3.3/3.6/3.7V/cell. Different batteries have different charge technique. There
are two methods termed as constant voltage and constant current. The charge current varies
according to battery capacity and specification. The final voltage is very important; it should
precisely match the voltage of the battery: LiPo is 4.2V, LiIo is 4.1V and LiFe is 3.6V. The current
and voltage of the battery should be correctly set.
When you want to change the values of parameters, please press START/ENTER key to make itblink and then use DEC or INC to change the value. Then press START/ENTER key again to
