Just yesterday I tried this setup. I'm amazed by the power it delivers, but somewhat worried. I heard this is dangerous. I'm using eFest 800 mAh batts button top.

Well to be honest I have read to not use stacked batts either - but If we can use them on the zmax V2 with extension - I find no reason to not be able to use them on the sigelei telescope - there are safety features in the PCB and vent holes - shouldn't be a problem

2013 Top Seller!! new OLED Zmax v3,8 stages
show work power, zmax rms zmax rms
1.5Amps or even bigger current
2.Protection against short-circuit
3.Output Voltage: 3.0~6.0v
4. battery ,two pc 18350 or 18650
So you're good
Do you really notice a difference between and 18650 and 2 18350?
And 2nd question
Are you using efest 800mah V2 bio? Those are the only efest batteries I would use if I had to use efest
Double check

Yes! They're BIO (I know nothing about batteries, just learning on the way).
The first noticeable difference is more power, as if it run a little hotter (I had it in RMS mode). Aside from that, it's too large a PV to carry around, and it only lasts until it hits 6.8v. I'll stick to 18650. In non regulated mods could make a difference, but not here.
Good to hear you are not going to stack batteries. Here is a good article on battery safety from Rolygate.
A short way down in that post he says:
'All explosions reported so far involve metal tubemods with two batteries in series'.
Yes, people do it, but unless you know the added risks and how to mitigate them, IMO it's safer to avoid this.

I guess I agree ryedan but its hard to state such a claim when every YouTube video from the top 3 (Grimm-pbusardo-Scott) all stack batteries in unregulated and regulated mods - so I tell people about the risks as well but then I say life is not life without risk - oh and also I say don't blow your face off
I dunno, maybe in their older videos from several years ago when stacking non-protected batteries like CR2's and stuff was considered normal rather than a pipebomb waiting to blow like it is these days. Stacking batteries can be dangerous, there's no doubt about that.
As I said, stacking batts in a non protected mod could be different. But in a regulated mod it's nonsense. Plus, the 33.3 chip starts hissing with this setup, something that doesn't happen with just one battery. I just wanted to try, I heard it was dangerous but these are protected. I use 18350 because they make a neat little package on my eVic... Just love it!
I understand that the PVs are different, and that no reference was made to any other equipment used, but I recently tried two 18350s in my Bolt and I near singed my tongue off. Using an 18650 instead, there was a HUGE difference.
The relevance?
I've noticed that many sites will state that one can use two 18350s, as well as an 18650 ... but in my experience, although capable, the two aren't comparable. Had they noted this on the site where I purchased my Bolt I would have researched the differences and saved my tongue a nasty burn.
Different situation, I know. But I figured I'd mention it, just in case.
