I use these for single-cell squonk mechs. I get a day or so of continuous use out of these, which beats my previous batteries for uptime. No more swapping in the middle of the day!
They don't hit as hard as some of my 20700 batteries (ampking), but they get the job done with time to spare. I use a 0.15-0.2 ohm braid for my adv and these last and hit nicely.
