Who knows who made this cell? It looks like the positive poles used by YongdeLixin in their 18650 cells, I have a pair of Golisi S30 (2nd generation, because the first version were Sony / Murata US18650VTC6 rewraps) which have exactly the same positive poles but they are cells which make 3000mAh see more…


I think you are right.
Similar to the YDL positive ….
