VOLTCRAFT V-CHARGE 300 TOUCH Handbuch Seite 73

Important when charging/discharging a lithium rechargeable battery pack with balancer
connection:
Multi-cell lithium battery packs usually always have a balancer connection. This permits the
charger to monitor the voltage of every single cell separately at all times.
The charger adjusts the voltage of all cells to each other if there are deviations. The balancer
prevents that one or several cells are over-charged or other cells not sufficiently fully charged
by this. The balancer therefore protects both from over-charging (which may cause fire or
explosion) and from deep discharge of a single cell, and thus ensures best performance of the
battery pack in your model.
Procedure when connecting a battery pack to the charger:
1. First connect the charging cable to the two 4 mm round sockets of the charging output.
Ensure correct polarity (red cable = plus/+, black cable = minus/-).
The charging cable must not be connected to the rechargeable battery yet!
2. If you want to connect a multiple-cell rechargeable lithium battery to the charger, plug the
enclosed balancer board into the corresponding socket of the charger.
3. Connect the charging cable to the rechargeable battery now. Ensure correct polarity (red
cable = plus/+, black cable = minus/-).
4. Connect the balancer connection of a multiple-cell rechargeable lithium battery to the cor-
responding connection of the balancer board. Do not use any force for plugging in! Ensure
correct polarity.
The minus connection of the balancer plug of the rechargeable battery should usually be
marked; the balancer board has the minus pole marked as well.
If the balancer plug of the rechargeable battery does not match the shape of the socket on
the balancer board (it is intended for XH plugs), you need to use a suitable adapter. You
will receive these in accessories trade.
