I have just coupled up my speakers and watched the video

He claims 75 kg for the 3.55 kWh unit - not bad maybe three times the weight instead of 200 times the weight

The guy explaining about it does not seem to be able to keep his kilowatts and kilowatt hours straight - which is a bit worrying

And they are 48v systems - seems a bit funny
My solar inverter is about 400v

He is also promising double and triple the power density "soon"

I hope it's gen!
