SPECIAL FEATURES
Special features
Optimized operating software
IMAX-B6 features the so-called AUTO function that set the feeding current during the processof
charging or discharging. Especially for Lithium batteries, it can prevent the overcharging which
may lead to an explosion due to the user's fault. It can disconnect the circuit automatically and
alarm once detecting any malfunction. All the programs of this product were controlled through
two way linkage and communication, to achieve the maximum safety and minimize the trouble.
All the settingscan be configured by users!
Internal independent lithiumbattery balancer
IMAX-B6 employs an individual-cell-voltage balancer. It isn’t necessary to connect an external
balancer for balancecharging.
Balancing individual cellsbattery discharging
During the process of discharging, IMAX-B6 can monitor and balance each cell of the battery
individually. Error message will be indicated and the process will be ended automatically if the
voltage of anysingle one cell is abnormal.
Adaptable to varioustype of lithium battery
IMAX-B6 is adaptable to various types of Lithium batteries, such as Li-ion, LiPo and the new
LiFe series ofbatteries.
Fast and storagemode of lithium battery
Purposes to charge Lithium battery varies, ‘fast’ charge reduce the duration of charging,
whereas ‘store’ state can control the final voltage of your battery, so as to store for a long time
and protect usefultime of the battery.
PC based analysisuing USB Communication
IMAX-B6 offer PCbased program cananalysis the characteristic of the battery
via USB port.It shows a graph of voltage,current, capacity curves. It also shows the
individual voltage ofeach cell in the Lithium batterypack.
PC-LINK USB adaptorcan be purchased separately

Maximum safety
Delta-peak sensitivity: The automatic charge termination program based on the principle of the
Delta-peak voltage detection. When the battery's voltage exceeds the threshold, the process
will be terminatedautomatically.
SPECIAL FEATURES
Automatic charging currentlimit
You can set up the upper limit of the chargingcurrent when charging your NiCd or NiMH battery;
it is usefulfor the NiMH battery of lowimpedance and capacity in the 'AUTO'charging mode.
Capacity limit
The charging capacity is always calculated as the charging current multiplied by time. If the
charging capacity exceeds the limit, the process will be terminated automatically when you set
the maximum value.
Temperature threshold*
The battery’s internal chemical reaction will cause the temperature of the battery to rise. If the
temperature limit isreached, the process will be terminated.
* This function is available by connecting optional temperature probe, which is not included in
the package.
Processing time limit:
You can also limit the maximum processtime to avoid any possible defect.
Data store/load
The maximum five batteries’data can be stored for users’convenience. You can keep the data
pertaining to program setting of the battery of continuous charging or discharging. Users can
call out thesedata at any time without any special program setting.
Cyclic charging/discharging
1 to 5 cyclic and continuous process of charge>discharge or discharge>charge is operable for
battery refreshing andbalancing to stimulate the battery’s activity.

WARNING AND SAFETY NOTES
WARNING AND SAFETY NOTES
These warnings andsafety notes are particularly important.Please follow the instructions
for maximum safety;otherwise the charger and the battery can be damagedor at worst it
can cause afire.
Never leave the charger unattended when it is connected to its power supply. If any
malfunction is found, TERMINATE THE PROCESS AT ONCE and refer to the operation
manual.
Keep the chargerwell away fromdust, damp, rain,heat, direct sunshine and vibration.
Never drop it.
The allowable inputvoltage is 11~18V DC
This charger and the battery should be put on a heat-resistant, noninflammable and
nonconductive surface. Never place them on a car seat, carpet or similar. Keep all the
inflammable volatile materialsaway from operatingarea.
Make sure you know the specifications of the battery to be charged or discharged to
ensure it meets the requirements of this charger. If the program is set up incorrectly,
the battery and charger may be damaged .It can cause fire or explosion due to
overcharging. This warranty is not valid for any damage or subsequent damage
arising as a result of a misuse or failure to observe the procedures outlined in this
manual.

WARNING AND SAFETY NOTES

WARNING AND SAFETY NOTES
To avoidshort circuit betweenthe charge lead always connect the charge cable to the
charger first, thenconnect the battery. Reverse thesequence when disconnecting.
Do not connectmore than one battery pack to this charger at any one time.
Never attempt tocharge 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 (Explosionhazard).
“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 protectioncircuit.
“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 currentsthe charger delivers during the charge process.
07

WARNING AND SAFETY NOTES
Please bear inmind the following points before commencing charging:
“Did you select the appropriate program suitable for the type of battery you are
charging?
“Did you setup 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 intermittentcontacts 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 arenormally gold-plated should be fitted to both ends.
