Got ENVY ?????????

[Big Screen D]

This is going to be quite a bit larger in diameter and heft than an eGo battery. I think it is a mistake to make the design any larger in diameter than an eGo battery. What this has evolved into is a hybrid IPro/Buzz Pro.

Hate to be a Debby Downer, but IMO this will not attract eGo users much more than the current product line already does.

 

[FranC]

I have to agree with that. I smaller size is needed.

OK this is my new design , 2 x 16340 Powerizer batts , same electronics as the BP and IP same batts as the BP so same specs , 18mm diam. 0.72"( same as the IPro ) x 4 " long tip to tip , so IP diameter and shorter then the BP . View attachment 66822
Back lit clear button with a Blue led , same wheel as the IPro

Question: is the beveled top cap the "cone?"

There's a couple of different ways of looking at that; if the 4" is from bottom to top of the connector, it's about 1/2" shorter than my BP—a noticeable difference, but admittedly not great.

On the other hand, it's about the same as the 1000mAh eGo batt I have sitting here (the eGo is a whole lot thinner, of course, but diameter isn't much of a consideration to me)

The Infinity Pro is over 5". My original Infinity is just under 5". I really wish this thing could be about 3 1/2". Some of the 16340 batteries were listed as being 1.2", while others were 1.4". Are there really differences in length, and if so, would that help shrink it a bit more?

As for the width, the Infinity and Infinity Pro are pretty slim devices. They are not really that much bigger, in diameter, than my VV eGo. I don't think that is an issue.

the BEST small batts I found lasted 3 3/4 hours of moderate vape time, not gonna cut it IMO !

still trying some other ideas.

What about future expansion? For instance, go with a 4 hour mini battery for the base unit, but allow the tube to be extended to allow for 8 hours+. Just make the expansion tube fit the battery cover threads. You may be able to release it at a lesser cost.

Cool thought, LD. A pair of 14250, extender tube to allow a pair of 14500 might be neat A relatively simple extra cost add-on, just an extender tube, reuse existing end cap.

A half Infinity, with a step up to being truly infinite. (OK, I know it's a fixed 510 fitting )

The problem with using 14500s stacked in a tube is that the PV would become even longer than the ipro. probably 5" in length which will pretty much make it useless and you'll be vaping a wand rather than something closer to the ego. I think the primary thing that needs to be changed is the lenghth. At least for me, what turned me off about the Ipro was the length of the pv. It order to get closer to the ego, you'd have to use the 14xxx in the smaller size but that would cut the mAh rating to the rating less than a standard ego battery which would be inefficient since it will be a VV mod. The only way i would find the 14xxx batts being used is if the voltage range is limited to 3.4-4.2 so that you can at least get some sort of battery life out of it. I personally think the only way to get something close to the ego form factor is through using a single battery with boost regulation and a customized battery to get mah ratings in the 1000+mAh area.

The way i see it, you have 2 options, either thin out the mod or substantially shorten the length of the mod.

 

[markfm]

To get that kinid of battery you might need the lithium sulfur technology, the big gain in energy density compared to standard lithium rechargeables. Unfortunately that's not ready for prime time yet, no consumer battery implementations that I've seen.

 

[LordDavon]

What if the 16430 was still used? You can get them in some higher mah ratings. A single battery could provide enough current to step-up and run at 4 hours. Adding the expansion tube could disable to step-up, and extend battery life.

 

[markfm]

Downside would be shifting to a boost circuit, since the current IP/BP circuit has been pretty well tested, debugged. Combined buck/boost would add yet another layer of complexity, I'd expect, more cost. On something aiming for higher production numbers a mistake would be really costly. There's got to be a decent sample size on the current design, which gives confidence in reusing it.

 

[LordDavon]

Then, just stay with the 16340's. Each battery is only 1.36" each (34mm) in height. There has to be a way to get the PCB and dials a little tighter at the top, to trim a little height off. As for width, since have Infinities to compare to eGo batteries, it really isn't much bigger.

 

[markfm]

It looks like that's where he is at. A pair of 16340, same as a BP, but about 3/8" shorter and 3 mm smaller diameter than a BP.

The Infinity Pro is 9mm smaller than the Buzz Pro, according to the Not Cigs web page. IPro is listed as .5" and the BPro is .86". .36 inch = 9.14400 millimeters, according to Google Calculator. It is about 40% smaller, and that is pretty significant.

As for the height, the BPro is listed at 4.25", so if he can get this under 4", it will be a nice little unit.

 

[markfm]

A 16xxx battery is roughly 0.63", without including the tube and some slack space.

A 14xxx battery, like used in Ipro, is 0.55", before allowing for the tube and a little free space to allow for battery production variability.

(the first two digits are battery diameter in mm)

Bp height of 4.25" is what I measured. I also measured 21mm BP diameter, which matches 0.83".

I think we need to get BuzzKill to take some measurements of the IPro for us. You are right though, I checked online and the 14430 is listed as .55". Not much slack space in the tube, so I am guessing it to be around .6". That does make the difference a bit less. Hmmm...

 

[markfm]

Typos happen.

I've purchased some Go-go products ... their 1300 mah battery is only slightly smaller dia than the IP, but much shorter, and they have a re-chargeable 18650 roughly the same size ... and they have a vv mod, not good quality tho I hear ... they are re-branded Hatch from Lifeking Technology Co., Ltd. Shenzhen City ... they (Lifeking) seem to be aiming for the same market you are

I think the 18650 comes in 3600mah, and is 2.5" tall. That may work, but will need a step-up circuit.
