I've been using this with a Dovpo Topside and running a 0.22 dual coil Pulse X RDA and so far I can go though an entire 10ml tank of liquid and still have a life in the battery (to be fair not much but still very impressive performance for a single battery so I'm will definitely say I recommend this thing for anyone using a mod that is designed to a 21700
I got 2 of these for my dovpo topside and I get a day- day and a half out of each on heavy vaping. Great for what I use them for.
Nice batteries. Last a while, but out of the two I purchased one dented in the negative connection in a charger that accepts 21700. Not sure if a quality issue or if I was unlucky but will not use it so only the other battery which has been charged a few times and has no dents is in use
Great service 100% value for money
