Okay, maybe this then. It seems like it's hotter around the top and creeping down. There wasn't anything touching the sides of the RDA, but maybe their just too close... If it's a high ohm build though, it won't put as much stress on my batteries correct?
When it comes to regulated mods, the wattage setting is what determines how much drain the batteries see. The batteries have to generate the wattage you set at their voltage under load. The device takes that raw power from the batteries and bucks the necessary amount of voltage down to the amount of current the coil needs to maintain the wattage you set at its resistance. On your mods, a .1 @ 100w pulls the same current from the battery as a .5 at 100w.
That's part of what makes them so safe. They can output more current than your batteries actually give them. What they do to power a .1 is nifty. At 8v, the batteries can generate over 150w of power for just ~20A. The device then takes a lot of that voltage and converts it to current to satisfy the draw of the coil, so that what actually hits the atty is 150w @ 3.8v and 38A. As long as you have good 20-30 amp batteries, you'll be fine with anything that it can fire.
And actually, lower-resistance coils can require less power and run cooler. It all depends on the mass of the coils. A dual 24g at .3 may require 80w of power to heat up, while a dual 24 at .1 wouldn't even need half of that power to heat up as quickly and will lose its heat more quickly.
If you're going by mech mod rules, wherein lower resistance means a higher amp load, more power, and thus more heat, then that seems counterintuitive, but it makes perfect sense if you think of it only in terms of wattage and coil size. A bigger coil needs more power than a smaller one.
When it comes to regulated power sources, the resistance only changes how the coils get their wattage. It doesn't change the amount of generated heat that one watt translates to. To go back to my previous example, 150w @ 8v and 20A does the same amount of work as 150w @3.8v and 38A.
Heat retention can be a problem with high-mass, high-powered builds. They take a lot of power to heat up quickly, but that also means the heat dissipates more slowly. The more mass a coil has, the more power it will need and the more heat it will hold onto.
If you want to get the heat retention down, you either have to use an RDA with more airflow/chamber space or build smaller coils. Try dropping down a gauge, decreasing the diameter, or taking a wrap out.
I noticed my mods were getting a little bit hotter than when I was just using the crown tank. Any help would be appreciated!
