11. Current drain
1. During the Equalizing phase the Top Equali-
zer draws a current of about 15 mA once the
Lithium charger has terminated the charge pro-
cess.
An additional by-pass current of about 70 mA
per output flows, but only for the period when
the LEDs are lit.
This means in practice that very little capacity is
drawn from the battery during the equalizing
process.
2. Current-saving mode
The unit draws a current of about 0.4 mA.
12. Accessories
A voltage sensor lead must always be used with
this unit, otherwise the device will be unable to
measure the voltage of the individual cells.
Robbe Lithium batteries are fitted with this sen-
sor lead as standard. However, the sensor leads
are also available separately, enabling the user
to attach them to existing batteries:
Voltage sensor lead, 3-pole (two cells) No. 4025
Voltage sensor lead, 4-pole (three cells) No. 4026
Voltage sensor lead, 5-pole (four cells) No. 4027
Voltage sensor lead, 6-pole (five cells)
Voltage sensor lead, 7-pole (six cells)
13. "Slave - Master" switching
Two Top Equalizers can be connected in series
in order to equalize more than six cells (max.
twelve cells).
If the individual cell voltages are to be displayed
on the charger's screen via the Equalizer sen-
sor, the two units must be interconnected using
a Master - Slave link lead.
With this arrangement you must set the first unit
to "Master", the second to "Slave".
See the wiring diagram in the centre of these
instructions.

15. Safety notes
• The Top Equalizer is designed solely for
equalizing (balancing) rechargeable Lithium
batteries (LiPo and LiFe).
• It is essential to protect the unit from dust,
dirt and damp.
• Do not subject the Equalizer to excessive
heat or cold, nor to direct sunlight.
• Avoid shock and pressure loads, and do not
subject the unit to severe vibration.
• Do not place the charger and the batteries
connected to it on any form of flammable sur-
face. Do not operate the charger in the vici-
nity of inflammable materials or gases.
• The unit should never be left operating unsu-
pervised.
• Ensure that there is an unrestricted airflow to
the unit's cooling slots. Never place it on a
carpet or felt surface.
• If you will not be using the Equalizer for a pro-
tracted period, disconnect it from the power
supply and any batteries connected to it.
• Do not charge a battery which is already
warm or hot to the touch. Allow packs to cool
down to ambient temperature before conti-
nuing.
• Batteries to be charged as a unit must con-
sist of cells of the same make, the same type
and the same capacity.
• Do not connect two batteries to one output
for charging in parallel. Only connect one
pack to the unit at any one time.
• Take great care to maintain correct battery
polarity; and avoid short-circuits.
• Read the instructions provided by the battery
and charger manufacturers, and adhere to
them strictly.
• At regular intervals check the case and
cables for damage.
