10. LITHIUM BATTERIES (LIPO, LIION, LIFE)
a) General information
The rechargeable battery programmes for LiPo, LiIon and LiFe rechargeable batteries gener-
ally differ only in the voltages and the permitted charging current, see table in chapter 7.
When charging a lithium battery, there are two different phases. First, the rechargeable battery
is charged with a consistent current. When the rechargeable battery reaches its maximum volt-
age (at a LiPo rechargeable battery, e.g., 4.2 V), charging continues at constant voltage (the
charging current drops). When the charging current drops below a certain threshold, charging
is ended and the rechargeable battery is fully charged.
If the rechargeable battery has a balancer connection (usually this is the case in
almost every lithium battery with more than one cell), the balancer connection must
be connected to the charger as well as the rechargeable battery’s cable for charg-
ing/discharging.
There are different types of balancer plug. Therefore, do not apply any force if the
plug does not t! in the charger or the balancer board! The matching adapters for
the balancer plugs are available as accessories.
There are also rare multi-cell rechargeable batteries where the cell connections are
separately routed out and that strictly speaking are not a multiple-call battery pack.
Therefore, always observe the information of the rechargeable battery manufac-
turer on the build and rated voltage.
When using a balancer (integrated in the charger), all cells of a multi-cell battery
pack have the same voltage after the charge process, which prevents the over-
charging of individual cells (danger of re and explosion) or a deep discharge of
one of the cells (damage to the rechargeable battery).
