What a difference a battery makes.
So I've been using my EVO since shortly before I reviewed it and loved it with dual coils. Worked best I found on the medium or high setting for the 1.5ohm duals. I only ever used it on the two batteries it came with, never really got any spares (which is inconvenient when it comes time to recharge.)
So I finally ordered some spare batteries from JRCT (Thanks, Switcher, the drip tip is beautiful!) and just finished charging the 16340s to swap out in my EVO. And suddenly my carto was giving out a burnt taste. Now, the current batch of SmokTech cartos have some serious QC issues and seem to last only a couple of days in a tank so I thought maybe it was dying, but prior to swapping batteries it was fine on the medium setting and I'd just put this one in yesterday, so it shouldn't be dying yet. I tried topping up in case the top coil was dry but it was quite soaked.
But then I noticed that my tank, and my blingy new drip tip, were getting warm. Very warm. Uncomfortably warm. And it clicked. These AW IMR batteries were putting out what seems like a lot more voltage. The medium setting on my 1.5ohm duals was now too much. Dropped it to the low setting and now it's just fine -- just as good as it was at medium on the blue generic batteries the device came with.
It doesn't seem to make sense on the surface -- it's a regulated device, right? It should be pulling the same voltage no matter what batteries, right? But -- and I'm no electrician, I know some basics, but my guess is that the lower internal resistance of the IMR batteries allows current to flow more freely and in larger amounts, which would allow the coils to get hotter at the same voltage level, while the blue pack-in batteries, having a much higher internal resistance and therefore not able to supply the same amount of instantaneous current, struggle to provide the requested current.
So, yeah. Big, big difference these batteries make.
