Connecting the battery

NiMH or lead acid batteries (Pb): first plug the charging cable into the 4 mm sockets on the side of the
charger. Now connect the battery.
Lithium batteries: Connect the Balancer adapter to the charger - the socket is polarized, pay attention
to the side guides. Then connect the charging cable to the 4 mm sockets on the side of the charger. Now
connect the battery to the balancer adapter and charging cable.
• WARNING: Use only batteries with XH balancer plugs. Never try to connect other plug types with
the charger! The plug or charger may damage or worse, the battery catches fire or explodes! If
necessary, use a suitable adapter cable.
• WARNING: The socket is polarized. The balancer plug must fit easily, do not use force! The plug
could be damaged or worse, the battery catches fire or explodes!
• WARNING: Before charging make sure check the type of the battery. Lithium batteries with more
than one cell must always be charged with attached Balancer - fire hazard!
• Note: 1S lithium batteries or batteries with integrated balancer have no extra balancer connector!

Charging methods

NiMH: will be charged by the constant current method with Delta-Peak cut-off. Here, the charging current
over the entire period remains constant, the battery voltage rises slowly during the charging process. At the
end of the charge, however, it falls back slightly. This so-called Delta-peak point is recognized by the charger
and used to stop charging. After shutdown the battery is charged with a very low charging current to prevent
a drop in voltage until use (trickle charge).
Lithium Batteries: are charged by the CC / CV method. Here the battery is initially charged with a constant
charge current (CC) until the battery reaches its final charging voltage (eg. 4.2 V / cell for a Li-Po battery).
In order to keep this voltage, the charging current is gradually reduced (CV = constant voltage). If charging
current is below 10% of the initial value, the charging process will be terminated.
Lead-acid batteries (Pb) are also charged by the CC / CV method.

increases very slow stop the precharge process
immediately - fire hazard!
