Thank you msfujino
I’ve seen your response on this topic, and this could partly confirm my findings.
But I still do not fully understand, why I’m getting such a high current during deep sleep. Because the values I find in the datasheet of the charge controller states lower values (if I read it correctly).
Might this have to do with the controller trying to find a connected battery, because it is not shut-down manually as advised in the datasheet?
