For the batteries with a round plug (DCJ 5.5 x 2.1 mm) we have developed a spiral cable with which the cable can be extended by approx. 50.

For our batteries we offer a wide range of accessories such as chargers and carrier bags.

Our 2S batteries bear the names of the districts of Berlin – our beloved hometown.
