The best (19 April 2022)

These are by far my favourite 21700 batteries they seem to hold there power very well I don’t have to worry about battery life if I am out all day and have one of these in my drag x pro

By Disco from Ross-on-Wye

Great battery (07 March 2022)

Bought one of these for my Voopoo DragX Pro… Great power, long charge, lasts all day & night at 50w whilst I’m chain vaping & chucking out big clouds. For best results, charge in a dedicated charger @0.5 amps… through your device is ok but batteries like a bit of TLC, so a low & slow charge and they’ll look after you

By Theadsi from Leek

Brill battery (18 December 2021)

Had the drag x pro mod was fed up of 17650 running out all the time 3 or 4 times a day so opted to by this battery best decision I made last all day at my usual use level can rate it better

By Alil from London

Really powerful batteries (11 December 2021)

Really powerful batteries! Lasting like 2 days if you smoke MTL on your device or even more depends on your taste.
They came extremely well protected and packaged and battery silicone cover.

Unsure (12 September 2021)

So, I’ve ordered four I think of these ones, the battery’s are great and everything however I’m not sure if it’s the battery build, my vape or just a general problem with having a larger surface area to damage with the bigger battery’s but one drop of the vape and the battery top dents in making it unusable. It does look like a flimsy bit of metal compared to another I have.. Anyway I have ordered the other battery’s available on vape club so I guess you’ll see a comparison review from me on those ones soon.
