So, I have a Weismic rx 2/3.
Running either a clone goon (0.17 ohm)
Wotofo conquerer (0.26 ohm)
Or smok tfv8 (ranges from 0.15-0.48 ohm depending on coil in using)
Just been having a read about battery amp drains from regulated mods increasing as the charge in the cells decrease.
Does anyone have any advice on 18650 cells to use?

I am running Samsung 25r batteries that state they are 20a so I feel they may be a little low rating for such low ohmage.
Thanks in advance!

Coil resistance doent really matter with regulated mods. What is important is the wattage that you vape at. The 25R’s will be good for about 140-150 watts in 2 cell mode or 200-220 watts in 3 cell mode.


Here is a good read on the subject.


In a regulated mod, Samsung 30Q’s or LG HG2’s are about as good as it gets.

Battery Testing by Mooch as of 12/2016 but I use it as my guide for 18650’s - I have one for 26650 somewhere if you want it
