The New Way


The perfect addition for your audio-setup...

The Stromtank offers the unique possibility to separate your hifi-system completely from the grid.

The Stromtank is a high-power battery pack with integrated pure-sign wave converter power supply – totally disconnects your audio system from the grid. With the Stromtank you can enjoy up to 8 hours listening to music before it connects uninterrupted and automatically with the grid to recharge. During the recharging process you can listen without any interruptions.

Premium home theatre equipment quality will improve both visually and sonically with the Stromtank.

Boost-function when connected to grid...

Even when the Stromtank is connected to the grid, the current pulses are not taken directly from the grid - they are absorbed by the battery. In the AC-connected mode the Stromtank creates a stable AC-supply (amplitude and frequency) and has less interaction between the grid and your audio- / video-setup.

The creator of this audio-declaration of independence is Wolfgang Meletzky – designer and founder of high-end reference components.

Stromtank – “made in Germany” – was developed in our Berlin factory. The tank is manufactured and assembled with noble and handpicked components.

What’s inside

The heart of all the Stromtank units is the innovative battery technology known as lithium iron phosphate (LFP). Stromtank uses a special type of LFP battery that offers maximum power delivery, extended battery life, voltage stability, and intrinsic safety. The lifetime of Stromtank batteries is ensured by a battery management system that was specially developed in conjunction with the Fraunhofer Institute in Nuremberg, Germany – experts in efficient battery management technologies.

Each individual cell provides feedback to the active battery management system. This intelligent system has three major functions:

• Active balancing of all cells in the array to maximize efficiency of discharging and charging cycles.

• Inspection of temperature, voltage, current load and state-of-charge of each single cell

• By monitoring and managing the battery array, the system is completely maintenance free
