VOLTCRAFT VC-1506 Bedienungsanleitung Seite 81

In addition, there is the danger of overcharging when charging such different cells (with different voltage) without the
balancer: The maximum admissible voltage of a LiPo cell of approx. 4.2V (+/- 1%) is exceeded (LiIon and LiFe data,
see chapter 7).
example:
A dual-cell LiPo accumulator pack charged without the use of a balancer appears to have a voltage of 8.4V and
thus appears to be fully charged. However, the two cells have a respective voltage of 4.5V and 3.9V (one cell is
dangerously overloaded, the other is half-empty).
A cell overloaded in this way may leak or, in a worst case scenario, catch fire or explode!
If your LiPo accumulator has a balancer connection, the charging program „BALANCE" should always be used.
If your „LiFe" or „LiIon" pack also has a balancer connection, the above information applies analogue, only the vol-
tage values differ, see chapter 7.
Monitoring the cell voltage during charging/discharging with a balancer connected
The battery charger's processor monitors the voltage of the individual cells of multiple-cell battery packs. The
voltage values are adapted by means of the balancer so that when the charging/discharging is finished, each cell
has the same voltage. By monitoring the individual cells, the battery charger also „notices" if a cell of the battery is
defective or if the connection is interrupted.
In such case, a relevant error message appears on the display.
+>
The electric connection via the connecting lead or the connecting
plug is interrupted.
The voltage of a cell is too low. Using the „+>" key you can jump
between the error message and the display of the cell voltages.
In this example the fourth cell is defective.
