Hi guys. Pretty new to vaping (ex roll ups smoker around 20 a day). I was using Voopoo mojo for couple of weeks but gave it to my other half and got myself yesterday Drag Mini. I do MTL and I did put t20s prism mtl tank on it 0.8ohm coils @16-18w using 50/50 12mg nicotine juice. Is it ok to use this tank with it? Is it fully compatibile etc? Sorry as kinda learning all this stuff. Also I was surprised the kit did not come in with a tank in the box is it usual? Will need to check how the battery perform as it just went dead since yesterday 4pm which looks pretty quick but will give it a first charge and see how it goes as my old mojo lasted over 1 day easily with the same tank and smaller battery
