AFE Problem with B300K

Product Discussion Expansion Battery
1

Hello there,
i purchased a new AC500 und 3x B300K
except 1 B300K all is working perfect!

with the one B300K i have the following problem, regardless if it is connected to the whole system, or just unplugged from anything else.
When i turn it on, after a few seconds the 20% light 40% light and the 80 light is blinking green, then it turns off after some time.
in the documentatition it says this is the code for “AFE-Failure”

What does it mean, and what can i do?
It doesnt even keeps alive long enough to make a firmware update i guess

I did spend a few thousand euros and im a bit frustrated.
I really hope you can help me.
kind regards
Marcell
