You got a link for these mate ?..
Well, it IS the most recommended(as reliable) UK source of batteries with great CS. Dodgy batch of well made clones can happen to even highly regarded shops(as Mooch says) from time to time. I haven't heard about it happen to Fogstar. Obviously, a wider range of products like18350, 18500, 26650 would be greatly appreciated. It may even be financially rewarded . Hi @Ben fogstar...... in before the fogstar vendor of the year lynch mob.
I think I found the LG HG2 batteries, are these the ones?

No, those are button capped batteries, by the look of it.
