I received an offer on Alibaba from a reliable seller I already work with for battery cells from this manufacturer:
https://www.bakpower.com/about_en.php
Does anyone have experience with them or know about their reputation?

In my testing of 50E equivalent cells, BAK had significantly higher IR dispersion than EVE, molicell, SAMSUSNG. Not tested this model.
On paper it looks like a very interesting mid power cell, alternative between 50S/P45/P42

Thanks for letting know.
How high was the dispersion in percentage?
Did it comply with the maximum value in datasheet, similar to like here it states <=5mohm
