I just watched your video. After watching your video, I double checked the 4 Samsung 30Q batteries I bought from Banggood last year, and they have 3-lobe top as well.
The 7x “slightly flawed” Green Samsung 25R batteries I bought from Trisky last year on his thread here, also have 3-lobe top. Phew 
Do you have any opinions on these Black Liitokala 26650 cells from Elsa’s Liitokala Office Store - 217753 on AE??? At US$15.88 for a pack of 4 before shipping costs, they are very appealing to me. Most importantly for us poor Aussies, this store will ship these batteries to Australia, at a very good and affordable shipping cost of only US$3.16
