Why should a CPO have a battery or what are the advantages of having a battery and what's the challenge I need to overcome when installing batteries. What we see in our discussion is that many CPOs are concerned that they are kind of the guinea pig for having batteries on site and combined with chargers. And they want to understand how exactly it works and is it possible to have a more or less plug and play ready system where it plays a battery. Just activate a checkbox somewhere and the system is working and running and it's reliable. And this is what I wanted to comment on what you said, Robert. Based on this integration which we have with FlectC charge, it's possible to use the batteries with every charger since you're using the OCPP protocol. MQTT communicate with our batteries and can also connect to the smart meter and orchestrate the whole asset on site as one controller.
