German Powerwall 280xLG 18650MJ1 7s40p+ 450Wp Balcony PV System and a small question
#14
Ok I got some more Information about the "flux problem":
It seems to be Ammonium chloride which is not problematic at 20°C with most stainless steels (the cell walls are of stainless steel, but I dont know which steel exactly). It also contains little amount of Zinc chloride, which is lightly corrosive to stainless steel Sad . I will clean it up with a flux cleaning spray and afterwards put a protective resin on top.

THX for the hint, these are the little things that can get dangerous with time.
