Smok xcube 2 Questions

[3ebmike]

You should be fine running those batteries.. If you're that worried grab some Sony Vtc 4s or something with higher amp rating. I really don't think you'll have an issue at all. I run Sony Vtc 4s in my IPV3li and it runs smooth no problem. I run the Tri coil tank all the time on my smok M80 plus which has two internal 18650s.. You don't have to worry about anything blowing up in your face.

i have seen a few battery tests conducted which rank the 25r, VTC4, and VTC5 as being roughly the same for temperature given a certain current. the sony batteries dont suffer as much from a performance standpoint as much at high current as the samsung but they do run hotter. from a safety perspective the temperature is what matters and in that respect they perform similarly. honestly if you are looking for constant high wattage output your best bet are LIPOs. all that i have seen so far are running 3 parallel cells which would make that possible. however, the 25r's in the xcube (which uses them in parallel to achieve over 75W) will work just fine.

as for the mech mod vs regulated there are protections in place on regulated mods which make catastrophic battery failure much less of an issue.

i actually found this linked already on the site (i cant post links yet):
TLDR - 0.2ohm, dual 18650, 140W the 25r performs best the longest. while at full charge the VTC4 does perform best however that is short lived. in all tests the hottest the batteries ever got was slightly above room temp. the test was 2s on with 8s rest from 4.2v down to 3.2v.

in the tests even at 25A none of the batteries had an issue with temperature in the slightest. pushing up to 30A they will be hotter but still well below anything which would be considered unsafe at all. keep in mind that this test simulates vaping your two batteries from full charge to dead without any breaks at all to cool off. in the test the sammy lasted longest at 109 cycles. in the real world the test wouldnt even be possible because you would have to stop to drip or refill your tank so many times that the batteries would completely cool off during that time.

I know this thread is dead. But I just bought this mod too. And I heard at over like 120w or 150 it pulses when you fire it rather than continuously go which makes it safer. I'm running samsungs in it cuz the shop was out of vtc4. But samsungs have more mah anyway.

Pulses?
Magic?

No, you will pick up a Pulse in TC mode - Temperature throttling
In Vw Mode, whatever it does, it does. It is actually called frequency modulation.

So how do you run 180w continuous? That's way over the rating of any 18650? I promise I'm not just arguig with you cxress. Just asking to learn. Missed you bro. Probably my favorite person on this forum.

Well, first, you are running 2, not 1, 18650's
Second, depends on several things. Resistance being primary and Internal Mod design another.
Just remember 2 things.
1) Quality Batteries for maximum safe performance
2) Batteries will not last long at 180w

*Built in safety features will not allow over discharge, however even Regulated mods cannot discern between Max continuous and Pulse limits of batteries.

Personally, I would not even attempt 180W
First, I have nothing that needs that much power and not enough experience to build anything requiring that much power.
Second, there are already better mods on the market more suited to the challenge.
RX200 comes to mind.

* I did run a TFV4/Quad-coil at 140w........once impressive, but way not what I prefer

Well its wired in series and I heard jt s parallel and you have 1.5 amps of the battery. I don't really run anything over 100w. My dripper that is. I'm currently considering getting a crown for if which you can apparently run up to 120w
