Yeah, hence my problem. At 100 watts, that thing has to be pushing close to 20 amps, right? I'm trying to figure out the C rating on this battery which looks like it might be 6.8 on the Brillipower website, but I'm not sure. How do I figure it out? And just the fact that I have to carry a charger with me, etc. is making it way harder than just throwing a .33 ohm coil that inocrrectly read .4 on my 50 watt Istick, and puffing on it for 2 days, with no charge. I like the feeling of a really warm, quick burst vape and all, but its just a hassle. I think I should at least switch to a dual 18650 with 120-200 watts, and just get 4 batteries to marry and rotate now that I spent the money on the charger. At least that will last me a day, correct? I mean, the 50 watt is over a year old so I know it ain't gonna last forever.
