Using the balancer for the first time
Connect your LiPo Balancer plus between the
battery charger and the LiPo pack you wish to
charge.
As a general rule you should first connect the
battery to the balancer using the white multi-pin
connector, before connecting the high-current
connectors to the balancer.
From this moment the device starts to balance
the voltage of the LiPo cells, even without being
connected to a charger.
To charge or discharge the battery, connect the
input cable matching your charger to your LiPo
battery charger; see picture below.
Charge mode
Connect a suitable genuine GRAUPNER Lithi-
um-Polymer battery (max. five cells) as descri-
bed above.
Refer to the operating instructions supplied with
your battery charger for the correct charge set-
tings.
Connect the LiPo Balancer plus as described
above.
The balancer differentiates between two opera-
ting modes: “Connect Mode” (connected) and
“Disconnect Mode” (not connected).
Disconnect Mode (not connected)
This mode is required when the balancer is con-
nected to a battery in order to balance the cells’
voltages, but no charger is connected. In this
mode the input is short-circuit protected.

Overcharging protection: over-voltage cut-
off
If a cell reaches the voltage of 4.26 V, the charge
process is immediately broken off in order to pro-
tect this cell from damage due to overcharging.
This may occur if the wrong cell count or battery
type has been selected on the charger, or if one
cell develops a fault. This single feature makes
the whole charging process many times safer.
The LiPo Balancer plus is connected to the batte-
ry both by the white multi-pin plug and also by the
standard high-current connector attached to the
pack. This arrangement avoids a falsification of
the measured results due to the influence of the
charge current, with the net result that individual
cells are perfectly balanced.
Checking the Lithium battery
! Caution !
Before you use your LiPo Balancer
plus for the first time, it is essential to check that
the pin assignment of the white multi-pin connec-
tor attached to your Li-Po battery is correct. The
best method is to use a voltmeter, e.g. Order No.
1955: clamp ammeter / multimeter.
If the pin assignment is incorrect, the char-
ger and the battery will be ruined. Explosion
hazard!
