No .. you don't want to exceed the C rating of a battery because it isn't safe.
Efest as I said has a 10 amp C rating. The Sonys have a 30 amp C rating. So you can push many more amps with your coils,if you want to,and be safe. High drain 18650 batteries with a C rating of more than 10 amps last longer. Hope that's clear as to why I am changing to Sonys.
Micro coils produce more flavor. The mod, whatever one you choose, is up to you as far as affordability or style that suits your taste. You've got a great start, but my suggestion for a jump to mechanical mods was made because you expressed the desire to learn about those.
I'm trying to learn as much as I can about ALL of it. I discounted the mech mods because it seemed like there were too many disadvantages at first glance. Now I understand there is just things you can't do any other way.
So if I don't care what it looks like... And I grab a tube from say... Fast tech...
Then buy GOOD batteries elsewhere...
What RDA's should I be looking at?
I genuinely, seriously, appreciate all the feedback so far. You guys have been great.
Should I just use the toolbox (vapers toolbox) app to figure out what wire I can use given my equipment's limitations? It appears that the VV 3 on paper can't run a coil lower than 1 ohm with its 3.5 amp limit. The lowest voltage it can go is 3.3. @ 1ohm thats 3.5 amps. What wire would you use to make 1.5 ohm / dual coils? (Or 1.5 ohm single?). Or are there other factors I need to know? I know length matters as well.
So adding more or less wraps is how you can tune length to a certain degree?
