So I was in my local B&M this weekend just perusing the new crap that they got in this week and saw they'd gotten a selection of new batteries in. The one that first caught my eye was a new 18650 Efest battery that is 3400 MaH. It isn't a really high amperage battery, but 3400 MaH is a reallllly long lasting battery that would be ideal for a vv/vw mod. I need a couple of them. And then I saw the new Sony 26650 and the little display sign in front of it. 50 amp. 50!!!!! I stopped dead in my tracks. And had to ask the clerk about it. "Wait. This can't be right. What gives?" He assured me that it was not some mistake. This Sony 26650 is literally a 50 max amp battery.
What does that mean? The highest amp rating on my 18650 batteries out there is 30-35 amps. And on those batteries, you can build coils to resistances FAR lower than I'm ever really interested in building. So since that's the case, why would I ever want a 50 amp battery? For one simple reason: I LOVE headroom. (I feel the same way in stereo equipment. It's not that you NEED a ton of usable wattage. It's that the music is far cleaner when the amplifier isn't being pushed.) I love not having to worry that this battery is going to not be safe. It would be next to impossible to actually stress this battery. Ever. I can experiment with twisted 24 or even bigger gauge wire to build coils with. I can fiddle and not even really worry about, well, anything. Even if I make a mistake, it's not likely to ever really be a safety risk. And I've wanted one good setup for a while that I can play like that with.
The fit and finish on it isn't up to par with a really high end device out there. This is definitely a clone, but it's not bad. The button is a little crunchy, but the throw is good. The locking mechanism is the tiniest bit flimsy compared to say the Caravela, but it's more substantial than the Nemesis by a good bit. The styling of the Big Nasty is not really my favorite. It seems to be, at the same time, a bit too simple AND a bit too flashy. In the end I think I really like the big ridges in the center and don't like the small ridges on top and bottom of the tube. BUT, I love how this thing feels in my hand.
Those big ridges in the center just seems to be really nice under your fingers. And the button throw is loose enough that you can press it with a pinky. That is one thing to think about though. With THAT much weight and a light button, you definitely don't want to set it down without the locking ring in place.
Of course, there aren't any toppers readily available on the market that match the diameter of the 26650 tube mod. So you're kind of stuck with a sort of step-down effect putting an RDA on top. Nothing seems to make the overall appearance not look like a nice flashlight. But from a functionality standpoint, there isn't much to complain about.
With this battery, I have been vaping with a pretty low resistance twisted 24 coil for 4 hours or so and I haven't noticed any considerable voltage drop. Wow. That is some kind of nice. With a reasonably good 18650 with a moderate dual coil build (totaling .5 ohm or so) I can vape for an hour or so before I feel like it's gotten weak and I need to swap batteries. Not with this beast. And because I'm hardly putting any strain on this mammoth battery at all, it'll likely last me for a long time.
It may sound like overkill, but I'd almost call this the IDEAL setup for someone just getting into rebuilding. The battery is stupidly safe. And the whole setup should last a long time even with heavy use. I'm quite pleased that I made this investment. It's not the prettiest setup on the block, but I don't have another mech setup that is anywhere near this good from a function standpoint. Now if they can just get this much power into an 18650, that'd REALLY be something to get excited about. It seems more and more likely with every generation of batteries.
