The various intercon­nection possibilities (parallel and in series) of lithium cells allow an even higher number of applications. Due to the progressive develop­ment of battery cells, their best possible intercon­nection and an optimal battery manage­ment system, almost any application can be realized today with the help of lithium technolo­gies.

The following features are ensured by our battery manage­ment system and various protective devices:

Safety and security

The reversible protective device (1st Level Protection) protects the battery against over­voltage, under­voltage, over­current and overtem­perature, while the irreversible protection device (2nd level protection) protects against over­voltage and short-circuits.


Due to the best quality of the printed circuit boards and components, the longevity of the product is guaranteed. In addition, Cell Balancing ensures the best capacity utilization due to balanced cell charge levels.


A built-in charge controller eliminates the need for a charger and is compatible with new techno­logies. The BUS systeme enables data extraction and transmis­sion to analyze the system. The application-specific total and residual capacity can be easily determined by so-called gas gauging.


A high-quality protective lacquer makes it possible to use the battery even in harsh climates. In addition, an ESD- and EMC-compliant design ensures that the components of the battery management system will not be damaged.
