The Battery Pack

Ettrak GmbH developed a modular and scalable battery swapping system, which is based on an
intelligent and standardised (IEC Standard) battery.

  • For mobile use such as notebooks, power tools, music players
  • More Energy Tubes connected together as the best solutions for pedelecs and e-mobility
  • Scalable as big units for energy storage

The standardised interface allows every application to access to the power of the tube. Every Energy
Tube has its own BMS and DC/DC converter. If needed, the tubes self-configure to the optimum DC circuit.

48 V scoop-proof, 100 Wh, non-hazardous material
