Looking for a parallel regulated box mod

I now use the VF clone for the nautilus mini and anything up to 30w, I ordered the iStick100w two weeks ago. I read good things about performance (not quality) but most say that it is a good mod (like you) so fingers crossed. And its damn cheap for a 100w mod. Bonus for me is that its another dual parallel. Might even get another one as a spare after I test it out. Delivery...any day now. Thank you.
Its cheap and it feels cheap...but it delivers. i bet parallel regulated will be the next thing, dunno why its not already.
My VF v3 clone is made by kangxin. It just performs ! Yes its dual battery and two batteries give a long vape time (with good batteries). It works with just one battery as well, thats how I knew it was parallell. Series mods wont work with just one battery...

The problem with regulated dual parallel is power limitation. Single 18650 cells can hit 75w (IPV D2). Cant see any regulated mods out there hitting higher than that with one cell. Any over 75w are dual battery wired in series or non removable battery or lipo. The VF is only 40w. This iStick is the first 100w dual 18650. The amp draw is split evenly between the two batteries so allows for higher watts. Technically if one cell can hit 75w, then two should be able to hit 100w no problem and split the amp load. A series setup has no problem to bump 8.4v to 10v. How the iStick can output 10v (on the specs) from 4.2v is beyond me. Any ideas? Personally I cant see dual parallel catching on. There are only two regulated ones that I can find. One I own, the other I've ordered. Anyone wanting 100w or higher will settle for a series setup and just switch batteries when they get low. What's becoming more commonplace in new high watt mods is 11v lipos hitting 200w. Given that millions already have 18650's, its a tough call to switch to lipo's...
Plus lipos are one of the most dangerous if they fail. They say the chemistry isn't safe. So there's that too
The voltage output is regulated with buck and/or boost circuits. Buck decreases the voltage above battery volts and boost increases it. Integrated buck/boost will of course do both. Essentially, each one does some magic that swaps amps for volts.
One 30 amp battery can output around 75 watts safely. With two batteries it doesn't matter if they are in series or parallel, you can get 150 watts from them. If you use one battery in a dual parallel mod the mod will run, but safe operation will be limited to what the single battery can support.
Just wondering, why are you more interested in parallel than series?
The batteries that are marketed as Lipo these days are not the same as the real Lipos of old. There are a lot of them in mods these days and none have ever to my knowledge vented or exploded. You don't want to drive a nail through one, but then again you also don't want to do that with a 18650.
all the new DNA200's are all lipo's I think. Come to think of it, the IPV3 Li is the only one I can think of that hits 200w with twin 18650's but that's Yihi, not evolv. I have at least 20 x 18650's and I'm sure I'm not the only one. what do I do with them if lipo mods flood the market....at least Li-ion are safer chemistry...
Hi, yes, a single battery in a dual parallel mod will work as long as you are at safe battery amp limit. There are loads more mods which are in series than the two I mentioned earlier. Parallel mods give you twice the vape time right ? At least that's what I understood.
Once you have a voltage regulator in the circuit it doesn't matter if dual batteries are in series or parallel. Two 30 amp batteries will safely produce 150 watts weather they are wired in series or parallel. They will also run for very close to the same length of time in both circuits, the difference between them being due to varying efficiency of the regulator in the two setups.
From Steam Engine:
Dual parallel at 150 watts using 2500 mAh batteries at 3.7V battery output: Batteries combine and make 3.7V and 5000 mAh. Combined battery drain is 45.05A which is 22.5 for each battery (parallel) and it will give you around 7 minutes total run time.
Dual series at 150 watts using 2500 mAh batteries at 3.7V battery output: Batteries combine and make 7.4V and 2500 mAh. Combined battery drain is 22.5A which is 22.5 for each battery (series) and it will give you around 7 minutes total run time.
Hope that helps
The thing with Lipos is they can safely output very high currents, higher than any 18650. They need to be rated for it, but if they are they're really tough and safe.

I just thought 5000mah would give twice the vape time of 2500mah. If you quote this from Steam Engine then I must have mis-understood. I still want the iStick 100w as its cheap for what it is. Will use that as a beater mod. I must relook at the SIG 150TC or the Snowwolf. TBH I do like both. Thanks for the heads up Ryedan.
I nearly bought that VapeCig VTbox DNA 200...what a disaster mod it turned out to be....they glued the 510 and it keeps falling out I read !! Jeez...
Don't buy the new lipo mods? You can't even change the batteries on them. What happens when they die? 200 bucks wasted. Honestly 200w is kind of enough. I can't believe they make mods that high. A year ago if you told me there would be 200w mods I would call you crazy. I'm gonna possibly but an x cube and maybe a snow wolf but after that I can't see why I need a more powerful mod. The only ones I'll buy is maybe ones that have super consistent tc or support more metals. We shall see. It seems like vaping should hit a threshold. Right?
