I tried this once more. I wouldn't charge. I started this around 12:45, went
off to another room around 13:10, when I came back at 13:30 the FR was dead,
no flashing LED this time, and no messages on the screen. This is what I had
on 2 shells:

and the last messages were:

Connection to neo closed.

Again, the "power_supply bat: driver failed to report `voltage_now" are from
the time when I switched batteries.

Anyone who wants to check it with this battery? Preferrably someone from
Berlin too but I can send it anywhere.
