• When connecting a rechargeable battery to the charger, always connect the charging cable to the
charger first. Only then must the charging cable be connected to the rechargeable battery. When dis-
connecting, proceed in reverse order (first disconnect the rechargeable battery from the charging cable,
then the charging cable from the charger).
Failure to do so presents the danger of a short circuit (e.g. from the two 4 mm circular connectors on
the charging cable). This can result in a fire or explosion of the rechargeable batteries!
• If you wish to charge battery packs that you have manufactured yourself, the cells must be identical in
their construction (same type, same capacity, same manufacturer). The cells must also be charged to
the same level (LiPo batteries can be balanced out using the balancer. This is, however, not possible
with other battery packs such as NiMH or NiCd).
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 respective channel (1, 2, 3 or 4) of the
charger. Ensure correct polarity (red cable = plus/+, black cable = minus/-).
The charging cable must not be connected to the rechargeable battery yet! Failure to do so presents the danger
of a short circuit, fire and explosion from the two circular connectors on the charging cable!
2. Connect the charging cable to the rechargeable battery. Ensure correct polarity (red cable = plus/+, black cable
= minus/-).
3. If the lithium rechargeable battery has a balancer
cable, connect it to the corresponding connection of
the respective channel.
Always observe the proper shape of the socket and
balance plug on the rechargeable battery.
Do not use any force for plugging in!
The figure on the right shows the connection of the
3-cell lithium battery pack with balancer cable.
