4.2v regulator question

[Mark Linehan]

I found this regulator and since I love 4.2v vaping, I was thinking that this might be a really nice selection for my next mod. I think VV are all interesting and fun but really, 4.2v is what I love. I find myself swapping out my batt's sooner than needed just to stay near the 4.2v more. Now, I had asked before about a 4.2v regulator and the ones I had found had drop outs that were too high, or too low or other problems. I have gotten a lot of my electronics rust off, but back when I was learning regulators were not really covered that well, so I wanted to throw this one at the experts and see if there is any reason that this might not work in a standard mod?

If this is an acceptable regulator then I would be using it in multiple configurations for most of the people I build for.

(2) 14500's, (2) 18650's, (2) CR2's etc, etc.. Mostly though, I work with protected ultrafire 14500's because they keep my costs down and since I build for friends and family at cost, I like to keep it inexpensive. Plus I have had a lot of luck with the ultrafire 14500's. I have 6 right now in rotation, and 2 of them I have been using almost since I started vaping with no problems.

So.. Any reason why I should not be able to setup this regulator with (2) 14500's in series?

If you want the linear regulator, you can use a popular 317 with two resistors precalculated for 4V2. The only problem with linear regulators is they're getting hot. To avoid that, you should do some switching regulator (either step-down from two cells or step-up from a single cell).

For the PTR08100W switched regulator, use the chart to select your voltage:

So for 4.2v you need a 328 ohm resistor

A fresh battery doesn't vape at 4.2v. Depending on the resistance of the atty and the size of the battery you could be vaping down at 3.7v or lower for small bats. Even with a 18650 an LR atty will drop to 3.9v fresh of the charger under load.

The regulator you (the OP) picked only handles 1.5 amps which is too low even for a 2.3 ohm 510 atty.

Mark,

That digikey link was to a non-stocked item. Min order 50, I think. I 2nd the LM317 or switched regulator. If you put a pot/trimmer on it, you could adjust it in the future too.

That was an interesting part tho, at 4.2 volts. The 1.5 amps MIGHT work, since it is not continuous use. It will probably only get a little warm with a heat-sink. But the adjustable 317/switched reg is more fun!

P.S. That beaver is sooooo damn (dam?) picky... lol ...his caution is ok tho; best not to push your luck on the amps. You didn't say what atty Ω

Well, right now I have been digging these e2 r4's, but as my atty's and carto's die lately I have been twisting my own nichrome replacements and made a couple of atty and carto from scratch. Gotta get me some rca connectors so I can have completely self sufficient e-cig mods. No 510 connectors or anything. That will be cool.

I was looking for a 4.2v regulator because I wanted a really easy and quick way to slap together a 4.2v mod for my people. As far as what Nuck was saying, I have set my VV mods to 4.2v and used them with e2 r4 cartomizers of the higher and lower resistances available on MadVapes, and with standard JoyE atomizers of roughly 3.2 in most cases. I don't know what the end - all - be - all voltage is when the vapor hits my lungs, but I know that I love vaping when my power source is at 4.2v, so that is what I am shooting for. I know that my EGO does not cut it any more. I have 1 EGO/tornado battery left from when I started vaping and I only ever use that as an emergency back up. I know that my 5v pass through is too hot for my liking with any of my purchased coils, but I do like my 5v with two of my homemade devices. One being a a standard cartomizer rebuilt with a 3.8 ohm coil and I like my 08100 VV box with just about everything because it is VV, but I never installed a meter on it. I will now that Madvapes is carrying those really cool battery meters that I think will slap onto my mod perfectly.

So.. All in all.. I am still looking to find me a nice 4.2v regulator for building my mods for others who have expressed a similar taste as I. It will just be cheaper and easier on me in the long run. I can not afford to buy 50 of them though. LOL

I am starting to like BreakTru's idea of putting a 328 ohm resistor on the 08100 more and more actually.

Thanks for the quick replies all. Great information as usual.

...even if you are ruining my evil plans as always! j/k

What's nice about the 8100 is that you can get it for free as a sample.

So are you saying I should get two?

Sorry I couldn't resist.

I am kind of on the same boat as you Mark. I like 4.1v as when the battery is reading that on the meter when I am checking it. I have also heard that the voltage will drop some when vaping. It is why I am going with the 8100. Mine is coming in the mail along with a new box idea for putting my Tekk mod into. Tekk box does not have enough room in it for me. It is nice looking and feels good but I mostly just want the guts. It is too fragile near the atty connector for me.
