This diagram should help:
Anyone tried this combo, the hammer in the standard 18350 mode with an 18350 inside (Let's call the vertical bat), with the 18650 tube on the atty side housing a second 18350 (Let's call this horizontal bat) in series with the vertical-bat?
It's not really going to fit. You'd have to screw like one thread on the cap to catch, and like one screw on the 18650 tube to catch. It'd barely be on and wonky as hell.
You'll have the same sort of issue stacking in the 18650 tube screwed in the regular way, it's really not going to fit.
I'm getting the impression maybe some people aren't understanding stacking
batteries. I'm not going to be one of those guys and insist you not do it, I'm just going to say it's a pain in the balls and not really worth it.
Just to clarify, stacking 18350 batteries doubles the voltage, nothing more. It WILL NOT double the AMP LIMIT or LIFE of the battery. So, visit your ohms law calculator and what not, and plug in 8.4V instead of 4.2V. You'll quickly get up to a 10A draw right below .9Ω.
Vapers stacked batteries back in the day to get more out of high resistance 3.5Ω store bought cartomizers when that's all there was (no RDA's). No VV devices too. And even when it was trendy, it was RCR123 3V batteries that were stacked, giving you 6V, not the 8.4V your getting by stacking 4.2V 18350's.
Some VV devices use stacked batteries with a buck circuit. But your getting voltage adjustment and regulation (amp safety limit) out of the hassle of maintaining stacked pairs and what not.
I'm not implying nobody knows this stuff here, just covering the bases. I found a YT video channel a few weeks ago with a guy clearly under the impression that the 30A on his Sony meant how much power was going through his Innokin SVD. So you never know what people are reading and then thinking...
Better ideas:
- Get a high wattage vape out of a Hammer by just using an 18650 and a sub-ohm coil. Use the reverse assembly trick if you want to keep the pipe look.
- Put a Kick 2 under the 510 cap by using the 18490 tube. I don't have my Kick around, but somewhere back in this thread is a Hammer owner rocking it that way all day. If I recall the tube won't exactly screw down quite all the way flush, but it works.
- Read through this thread. Everything that can be done to a Hammer with success is pretty much covered at some point in this thread. There's a lot that can be done with the Hammer, it's part of it's curse and charm.
