Introduction
Tahmazo T6B Max Lithium Cell Balancer is designed with detail and care when it comes to lithium
cells management. T6B Max is easy to use and balances your lithium packs, bringing the individual
cells in the pack to the same voltage.
Balancing lithium cells is necessary because the individual cell tends to decline to different states
of charge or voltage levels when they are discharged during its application. The Tahmazo T6B Max
will ensure, during the charging process, that the individual cells are optimally charged to the
same voltage.
T6B Max Balancer will protect your battery, and even your property, with its specially designed lithium
protection circuitry. The T6B Max will automatically shut-down the charging process if the cell-count is
not set properly or when the pack is already ‘balanced’.
When a lithium pack is connected to the Tahmazo T6B Max, the T6B Max will start to balance or
equalize the lithium cells in the pack. The Tahmazo T6B Max takes cell balancing one step further,
giving precise cell voltage when it is interfaced with selected Tahmazo chargers*.
You can link 2 x T6B Max Balancers to balance up to 12-cell lithium pack.
* Selected Tahmazo chargers includes Tahmazo T15 AC/DC Power Up and Tahmazo T30V2 Active Power charger

Start Using Tahmazo T6B Max Balancer
A. Using T6B as a standalone balancer
Switch T6B Max to ‘Master’ mode. Then connect the
battery pack with the proper harness to the balancer.
(The balancer will check the lithium cell status for a few
seconds). The Status LED will be lighted (‘ON’) when the
balancer starts to balance the cells.
Cells are balanced Cells are not balanced
The balancer
will flash the cell
count (5 times) and
then powers off.
The LEDs will start flashing
rapidly to indicate that
the cells in the pack are
not equal. The balancer will
start to equalize the lithium
pack until the pack is
balanced within 0.005V.
B. Using T6B Max with a charger
• Connect the T6B Max Balancer’s 4mm charger
connectors to the charger.
• Set the proper voltage and current on the charger
according to the battery pack’s specifications.
• Switch T6B Max to the ‘Master’ mode.
Then connect the battery pack with the proper
harness to the balancer. (The balancer will check
the lithium cell status for a few seconds). Then the
Status LED will be lighted (‘ON’) when the balancer
starts to balance the cells.
• Press the MODE button once and the status LED
will flash to indicate that the Connection Mode
is now activated. (In connection mode, T6B Max
Balancer is connected to the charger while the
battery pack is connected to T6B Max Balancer).
• Start the charger.
• Once the charging process is completed,
press the MODE button once and disconnect
the balanced lithium pack.
C. Using T6B with a discharger
• Connect the T6B Max Balancer to the charger
using the 4mm gold input connectors.
• Set the proper voltage and current on the
discharger according to the battery pack.
7
Active Balance - Cool Blue Balancer
• Switch T6B Max to the ‘Master’ mode.
Then connect the battery pack with the proper
harness to the balancer. (The balancer will check
the lithium cell status for a few seconds). Then the
Status LED will be lighted (‘ON’) when the balancer
starts to balance the cells.
• Press the MODE button once and the status LED
will flash to indicate that the Connection Mode is
now activated. (In connection mode, T6B Max
Balancer is connected to the charger while the
battery pack is connected to T6B Max Balancer).
• Start the discharger.
• Once the discharging process is completed,
press the MODE button once and disconnect the
discharged lithium pack.
Using T6B Max With Tahmazo T15 AC/DC
Or T30V2 (using the interface cable)
For Charging
When using the Tahmazo T6B Max Balancer with
Tahmazo chargers, the T6B Max data interface
cable can be connected to the Tahmazo chargers.
In doing so, the voltage of each cell and charging
data will be displayed on the LCD display on the
Tahmazo chargers.
The charging sequence is the same except:
• When the battery pack is fully charged, the balancer
will automatically power off, and
• You can view the charging data including voltage of
each cell on the LCD display.
For Discharging
When the Tahmazo T6B Max Balancer is connected to
the Tahmazo charger/discharger using the interface
cable (included with T6B Max Balancer), the discharging
sequence is the same except:
• When the battery pack is fully discharged,
the balancer will automatically power off, and
• You can view the discharging data including voltage
of each cell on the LCD display.
8
Active Balance - Cool Blue Balancer
• In extreme cases – defective cell, very high
battery capacity, and substantial voltage
differences between individual cells –
the balancing function may not reach a
conclusion even in “Disconnection mode”.
If this should occur, the T6B Max will prevent the
cells from becoming deep-discharged by switching
automatically to current-saving mode when any one
cell falls to 2.75 Volts (LiPo) or 2.35 Volts (LiFe).
In this case, the battery should be recharged again
as soon as possible.
Note:
If the monitor LED glows for a long time or continuously,
you should switch to Disconnection mode, as the Balancer
only switches to current-saving mode when the battery is fully
balanced if set to this mode.
Current Drain
During the balancing process, the T6B Max Balancer
draws a current of about 15mA once the charger has
terminated the charge process. An additional by-pass
current of about 70mA per output flows but only for a
period when the LEDs are lit. There is minimal current
drain from the battery during the balancing process.
In the current-saving mode, the T6B Max Balancer
draws about 0.4mA.
Monitor LED
The flashing rhythm of the monitor LEDs is a guide to
the voltage of the cells in the pack.
Monitor LED Indicates
Off Cell with the lowest voltage
in the pack
Flashing Cell voltage differs only slightly
from the cell with the lowest
voltage
Lights up for
long time,
continuously
Cell voltage differs significantly
from that of the lowest cell
• After the charge process has been terminated it is
possible that individual monitor LEDs will continue
to flash sporadically, but this will only occur if the
battery is a high-capacity type, and/or if the cells
in the pack exhibit significant voltage differences.
If you switch the T6B Max to “Disconnection mode”
(by pressing the Mode button), the battery can be
left connected to the unit. In this mode, the unit
continues to balance the pack by discharging the
individual cells as required.

Error Messages
Error will be indicated by the STATUS LED. The error
indication will show for 10 seconds and then the
balancer powers off. Press the MODE button while
an error is being indicated to clear the error and
connector’s status.
Master-Slave Mode
The balancer should be set to Master when it is
operated singly. For slave mode, please refer to
Other Balancer Configuration. (Below)
Other Balancer Configurations
There are two ways of using two Tahmazo T6B
Max balancers simultaneously for balancing up
to 12 cells lithium cell-pack.
Configuration 1 – ‘Dual Battery Connection’
(See Figure 1)
• Switch one T6B Max to the ‘Master’ mode,
and the other balancer to ‘Slave’ mode.
• Connect the ‘Master’ T6B Max Balancer’s
data interface cable to the charger.
• Connect the (+) positive (red) input cable of ‘Master’
T6B Max Balancer to the charger’s (+) positive
output connection. Connect the (–) negative (black)
input cable of ‘Slave’ T6B Max Balancer to the
charger’s (–) negative output connection.
• Connect the (–) negative (black) input cable of ‘Master’
T6B Max Balancer and (+) positive (red) input cable
of ‘Slave’ T6B Max Balancer to a charger as shown
in Figure 1.
• Connect the network cable between two balancers.
• Connect the lithium battery pack’s output connectors
and balancing connectors to ‘Master’ Balancer and
‘Slave’ Balancer in order within 12 seconds. (If the
lithium battery pack is not connected to ‘Slave’
Balancer within 12 seconds, ONLY the ‘Master’
Balancer will work singly.)
• The charging and discharging of the lithium battery
packs connected will be according to the instruction
of the charger/discharger.
