What is this new feature that turns your ac300 back on after discharging?

Product Discussion BLUETTI Apex & AC Series

I’m reading in the community that there is a new specific feature software update that can turn your AC300 back on after the required discharge…the topic I read and the response from Bluetti is that it drains to 5%, turns off, then back on???
2 things:

  1. I thought the B300 had to be drained and the AC300 to be fully off.
  2. If this is so, how does this work with a combination of B300 and B300k?
    Thanks.
