CHARACTERISTICS
WARNING
Loads above the electrical parameters can cause permanent damage. Permanent loading of
the system with absolute maximum values can influence the reliability and lifetime of the
system.
It is therefore recommended to operate the system only within the range of the nominal
specification.
The system may only be connected to chargers approved by Probst GmbH that comply
with the performance data of the product.
The following tables show the electrical specifications of the battery system. Table 3 shows the
performance-related characteristics of the system.

1Power reduction depending on temperature and state of charge. Information on this in the parameter list
The maximum number of parallel connections is 4 systems.
The following table shows the maximum permissible current values set by the factory as a
function of the state of charge and temperature. The term
charging stands for both charging
and recuperation.
