Just to mention that all the reviews of the Liitokala 26650 I have seen show at least 5,000mah capacity, my own review included.
Here is the link to the reviews of the cell on this site LiitoKala 26650-50A 5000mah 26650 - great first impressions
Some posters have found that they won”t work in series without a magnet or other spacer to make contact but some find they do.
I have 6 of the cells & mine make contact fine in series in both my S70 & Z1 with no spacer :+1:
