If i have equipment accurate enough to measure two 0.19ohm coils separately, logically I have equipment that allows me to make a 0.095 dualcoil build.
Considering i don't mind damaging and recycling my batteries more often, and am not planning to pull power for longer than 3 seconds at a time there should not be a problem with going over the cdr, (esp with parallel cells) APART from sped up degradation of the battery. Switching to n80 will give me a resistance boost up to about 0.17 which is going to pull 25.5A in perfect conditions (read "without ANY other resistance, i.e. atomizer, mod (negligible, in cases of high-grade copper and the like (but honestly, it's still quite small)) and battery.). in realistic conditions it will probably come up to about 0.18-0.19, which is at most a 23.3A draw on the battery, and as a result is totally safe.
according to Mooch's pulse test (5 sec on, 30 sec off), the peak temperatures of the 40A and 50A draws on a VTC5a result in temperatures between 61 and 76 celsius, which, while not healthy for the battery, is not high enough to cause venting or thermal runaway (which is quite hard to get with IMRs in any case.).
TL;DR
From what i see from the tests, VTC5a allows you to pull 44 amps from it without reaching 80+celsius, _if it is not fired continuously_, in which case i point to the previous statement about <3 second presses with rests in between.
Even so, I am planning to change to nicr80 as the material for my mech builds, and in that case the point is moot.
P.S. I would really appreciate if you pointed me in the direction of subohm builds that you _would_ run in case of a single vtc5a, considering there is 0 chance of misclicking. (it's not going to spend any time in bags or such.)
