Looking for boxmod recommends: needs stepdown and RMS V. regulation

Howdy!

Just subbed up to ask this, but long time lurker.

So, my deal is I currently have a Sigelei 50w(v2) using a subtank mini @ .5 on the RBA @ 15w (not that it matters, as talked about below) and the Subox mini kit, using the RBA for @ .5 ohms as well. I have been literally going crazy for the last few months trying to figure out what was wrong with my builds or whatever, as no matter how I built them, I was still getting very hot vape @ very low wattages on the Sigelei.

Turns out, each of my mods has differing issues. For those that don't know, the Sigelei 50w uses the YiHi SX330 board, which does NOT have stepdown voltage capability. So the lowest voltage output you're going to get is 3.6-3.7 volts, regardless of what it tells you on the screen. I literally was pulling my hair out due to this, as I KNEW it wasn't decreasing voltage....I just had to search forever on the webs to get it confirmed. Anyway, now I know...and this just is too hot for me, and there isn't way around it, other than increasing resistance and voltage to get into the green of 3.7v or more.

The Subox (or KBOX mini) has a similar issue, in that it is using what's referred to as MEAN voltage regulation, instead of RMS. MEAN gives you the average voltage between peaks in a Pulse Width Modulation setup (PWM - is used to to control the output voltage, which is allows you to have use more or less power as desired.) This will result in actually producing a much hotter vape than expected at the desired setting due to the spiking, I believe. RMS will give you a much more accurate feel of vaping at your desired voltage. This is somewhat more manageable, as you can get it right, but you just have to go by feel instead of what the display tells you. 10w @ .5 ohm works for me here.

So, long story short...both of mods have issues, and I would love to get a recommendation for a box mod that can take a .5 build able to handle output 50w (25w may even work), that does stepdown capability and utilizes RMS.

(Also, if I've spoken incorrectly, please educate me (politely, preferably))

Thanks in advance for your help!

There are literally hundreds of devices out there that fit your criteria. Here's a link to help you determine some of the different mods, and their ranges that are available. http://www.steam-engine.org/modrange.asp As to RMS or Mean neither is really wrong it's just more common to find RMS used in the vaping industry as it's easier to compare one device to another since RMS is DC equivalent. Adding your device style preference, budget etc.. may get you better answers.

My apologies, and thanks for the reply. Device style....eh, not too picky here, as long as it works. I've used tubes and boxes, so not opposed to either. 50w is likely plenty and I don't really want something the size of a VHS tape in my hand, if that can be avoided. Not really a cloud chaser, just enjoy the sub-ohm vaping.

Budget would be @ or around $100, and while cheaper is usually better for me, quality is important as well.

And I know there are many to choose from, but was hoping maybe someone had recommendations based off of experience.

Thanks again.

I just got my IPV4s, so of course its awesome. Steps down. Running a 0.28 ohm build at around 2.8 volts. Not really working the thing, but loving the flavor this billow V2 is giving me! Its a dual batt mod, so kinda large, but nice and curvy, so its not bad in the hand...

I like the look of it, esp. in black...didn't they have some issues with those when they were first released? I remember reading about some catching on fire or something or some other craziness. Have they addressed those problems?

What is the battery life like?

We vape similar resistance and voltage, so interested in your responses. Thanks!

They took care of the issues by leaving the charging board out of the newer V4s
Also I get about 2 days on the batts..and swaping out batts is fast and easy..love my V4's.. I have two of them now, running the awesome Crown subtanks...

+1 Due to my vaping, I'm getting 1.75 days with Sony VCT5. Still waiting for my Crown tank to arrive.

The issues were related to the charging board. They removed that from the "s" model. I put a fresh set of 25r's in Tuesday evening. So far two fill days. Indicator shows ~ 2/3 to 3/4th full. Batteries measure ~3.8 volts. I am a fairly light vaper. Maybe used 4-5 ml's of some mostly vg juice...

I think I might try the IPV4s. Looks like I can get it for around $60 bucks, which isn't too bad at all. Thank you guys for the input...I appreciate it. I like the Crown tanks, too, but prefer the ability to rebuild with an RBA portion a la the Subtank.

Thanks again!

I also recommend a VTC Mini... assuming you're looking for a small pocket friendly mod. The IPV4s is huge.
Good call actually. I'm used to the Sig 50w and Subox Mini, which are comparative to the VTC mini...I think you've changed my mind. Reviews seem really good for it as well. Thanks!

Glad to help! :D The VTC is actually smaller than the Subox and the Sig 50 even though it's more powerful. You're going to die when you see the screen. Best screen on any mod hands down.

I watched RipTrips review on it, and yeah, that stuck out big time....really nice, crisp clear and easy to read. I don't think I'll be going with the Cyan color, but the display was very nice. :D

Smaller than the Subox? That's pretty small...wow.

I hear you on the cyan color. I went for the black one. Yeah, it really is tiny. Only the Cloupor Mini+ and maybe the IPV D2 is smaller among single 18650 TC mods, although the D2 heavier, thicker & has the typical awful IPV paint finish.

I bought the full kit that came with a eGo One Mega tank. If you decide to go that rout you should pick up the CLR heads. They're rebuildable and much better than the normal CL heads. I thought the tank sucked when I first got the kit but with the rebuildable heads it's a better tank than my Subtank or my Lemos. If you already have a nice selection of tanks or you don't like rebuilding heads then I recommend skipping the full VTC Mini kit and just getting the mod. That said, the eGo One Mega is my favorite ADV tank. I love the Crown, but it goes through so much juice and I don't need to blow massive clouds all day.

Well, I currently just use subtanks, a V1 mini and the mini that came with the subox kit. I don't know what the deal is with the V1, but I just cannot get it to not dry hit. I even built a 1.2 coil for it to get out of the stepdown issue, but its still dry. I dunno.

Anyway, just saw this, as if someone was looking out for me:

http://vaporjoe.blogspot.com/2015/10/rollout-joyetech-evic-vt-mini-kit-4275.html

The description says it includes the tank, but that doesn't appear to be what the actual page from ecig says, so I'm going to investigate a little more...either way, it's a decent price, but would be killer price if it includes the tank.

Confirmed that the deal posted is incorrect, and it doesn't come with the tank.
