Do you have a link to that video?

This guy says its two 18650s:


Lipos would make more sense though.

 

[USMCotaku]

Yes, lipos would make more sense......there I'd a strong possibility of him being wrong........there are Lipo batteries packaged like an18650, as seen in mods like the IStick.

My thought was he is wrong as well.

Found in a Google Search for EHPro SPD A8. I found nothing e-cig related searching for eKits G3.




Sorry for the late reply. I see the video was already posted here.

I am not getting my email notifications about new posts here today.

Just curious. Do you have any links to LiPos that are in an 18650 casing?

No. I don't have a source for them, I just know that's what is used in many of the smaller internal battery VW mods

I keep seeing mention of their existence, so that has me wondering if I should try to find some.

In most cases it would appear that what we call lipo are simply li-ion batteries that are in a pouch instead of in a metal casing. This is what wikipedia says:

The denomination "lithium polymer" has caused confusion among battery users. It may be interpreted in two ways. Originally, "lithium polymer" stood for a developing technology using a polymer electrolyteinstead of the more common liquid electrolyte. The result is a "plastic" cell, which theoretically could be thin, flexible, and manufactured in different shapes, without risk of electrolyte leakage. These batteries are available[1] although the technology has not been fully developed and commercialized,[2][3][needs update] and research is ongoing.[4][5][6]

The second meaning appeared when some manufacturers started applying the "polymer" denomination to lithium-ion cells in pouch format. This is the most extended use nowadays, where "polymer" went from indicating a "polymer electrolyte" to mean a "polymer casing", that is, the soft, external pouch. While the design is usually flat, and lightweight, it is not a true polymer cell, as the electrolyte is still in liquid form, albeit it may be "plasticized" or "gelled" through a polymer additive.[7] These cells are sometimes known as "LiPo", however, from the technological point of view, they are the same as the ones marketed simply as "Li-ion", as the underlyingelectrochemistry is the same

Thank you for this post!

I had often read about people being concerned about using "LiPo" batteries, and now I see why. Without the metal casing that is typical of an 18650, the "pack" are much more susceptible to damage from handling. This article helped to explain why that is.

I don't really want to turn this thread into yet another battery debate, but there IS a difference in the chemistry of the Lipo packs and the 18650 Imr's we are using. This difference can be seen in the flatter discharge curve and superior wH run time of the Lipo packs......why do you think one of the things people raved about on the istick when it first came out was its surprising battery life?

I'm in no way an expert on batteries, I base this only on what I read, but at battery university you can read the following:

Li-polymer can be built on many systems, such as Li-cobalt, NMC, Li-phosphate and Li-manganese; it is not considered unique battery chemistry. Most so-called Li-polymer packs are for the consumer market and are based on Li-cobalt.

With gelled electrolyte added, what is the difference between a normal Li ion and Li ion polymer? As far as the user is concerned, lithium polymer is essentially the same as lithium-ion. Both systems use identical cathode and anode material and contain a similar amount of electrolyte.

So, if I understand it correctly, lipo isn't a battery chemistry per se.

Because they had 4000mAh.

The original 20W was 2000mAh, but was configured in AVG instead of Mean, so it ran Hot. People could turn the Watts down to get the same Vape they were used to at what appeared to be less Watts.

Looks like there's a new mod coming, the Ehpro SPD A8. Looks interesting....user upgradeable firmware, built in 4000 mAh battery, interesting looking design......

I'll be watching this one. I'll fill in more info as I find it

Darn, you lost me at Built-in battery.

Um, no [emoji14]
Actually, it was regulated via mean instead of rms.....had they regulated rms, the battery life would have been better, not worse.

They had such good battery life due to Lipo batteries flatter discharge curve, giving a larger vapeable range before minimum voltage is reached.

I'm actually over swapping 18650s, and am hoping more come out with good internal Lipos [emoji14]

Well, watched the video, and one concern was answered......it supports Ti.....a must these days [emoji14]
