So I got my first mech on Friday. One of these: A wondervape 270 mech kit. I was a bit concerned about not having the right RDA and fresh batteries so after watching more reviews than I could actually stand. I though this would be a alright kit to start with. After getting home, battery went onto charge and left it there until it was charged. When charged battery was reading at 4.2V, according to the manufacturer it is rated for 40A, but I think that is possibly on the generous side. So I spent Saturday watching and reading reviews on the battery, and it seemed that most rated the battery closer to 30-35A. Using this I decided that assuming 30A would be the safest option and to not push past that. Then came my rda setup, which was a dual coil build that was reading at 0.29Ω Now came my highschool physics and after running the numbers though Ohms law I got the following: At 4.2V: 14.48A @ 60.83W At 3.6V: 12.41A @ 44.69W I had taken 3.6V as the lowest I would run the battery, I am honestly not sure if this is the right cut off point or not? But taking the above so far and having used the mech for a little bit everyday since Saturday, I have really taken a liking to mechs. Is there anything else I may have missed above other than the 3.6V of the battery as the limit to stop?
