I have a feeling that buGG might be doing something so let's wait on that. If nothing happens there, what we should do is a list of Li-ions that are OK: what is the smallest viable size - then list the all larger sizes as they would be OK. Same for Li-Mn and LiFePo4. Then list what manufacturers products are OK in each of those sizes. Also list some of those not suitable.
There is almost certainly a way to make that into a chart, but first I guess we need the info:
- what is the smallest protected Li-ion that will safely run an atty?
- ditto Li-Mn
- ditto Li-FePo4
- what manufacturers do we know comply for each type/size?
- which of those currently used don't comply?
You could probably make a chart with a green area (good choices), an amber area (possible but more risk), and red (not suitable). But anyway, a list comes first. Let's argue about what is in or out before working up a chart.
no, i'm not presently working on a chart or anything. i like drozd's "gluttony" for such a project, and i agree that it would be really cool to actually see. it's a daunting project for me because there are just far too many batteries available across the various sizes and chemistries, and even common sources like dx, eBay, dino direct, kaidomain, best offer buy, etc., may offer any number of them without actually giving you any valuable specs to properly gauge their behavior and performance with a given atty and across the cycle of the battery. very cool to think about, but too intense and variable for me.
there may be some opposition to this, but again i suggest sticking with the five battery approach. you could get every battery in IMR, IFR, ICR, even INR below 16340 and chart them with a given atomizer at a given voltage, loaded or unloaded, but it's more helpful to know that none of them will safely handle the amp draw of a vaping application and most will require special charging considerations. you can look at any number of 18650 batteries and higher, and graph each accordingly, with varying results, but ultimately most if not all commonly used 18650s, regardless of their chemistries, will meet the demands. in between you really only have four battery sizes, across three chemistries, and three manufacturers that meet all the safety and performance requirements for vaping. there are more when you begin to do the math and think about what applies for a low resistance atty but not a Joye 306, or a Joye 306, but not a KR808, or a Joye 510, but not a SLB 510, or all high resistance atomizers even though no one is likely to use them outside of running batteries in series. the easiest, and arguably the best advice to give someone is to only use an
AW IMR16340, an
AW IFR16340, an
AW IMR14500, a protected
AW ICR17670/ Pila 300S/ WE-LRB168B and a protected
AW ICR18500/ Pila 600S /WE-LRB150A if they are using
any battery for a mod
smaller than an 18650. doubtful, but there may be some IFR14500 and IFR 17mm, but likely only 18500 and above that meet these specs. if so, i don't know exactly what they are. after that there are more and more choices to be had, across chemistries, and because of the increased energy density in IMR cells coupled with lower runtimes, i would recommend a good protected AW ICR cell at those sizes and higher anyway as i don't want to even
think about a user overcharging an IMR26650 or causing a dead short and releasing all that current. yes fuses are excellent options, and all the mod-built safety features as well, but what's even safer or ultimately safest in my opinion, is only using the batteries qualified for the job to begin with, and of course charging them properly.
in sum, i think it gets complicated and can span several pages of information that is indeed useful, but likely to be overlooked or misinterpreted, all because there are all these different options available and to the layman on the surface it would appear that it's all too much to take in and take seriously, or that a battery is a battery is a battery... just get the size you need and maybe think about an IMR if you are going to use a LR atty and if you have the extra cash or if you like the color orange. of course this is oversimplifying the matter, but the most helpful information will be presented in the simplest form...and if we are concerned about chargers having acceptable charging rates for our commonly used battery sizes, if we are concerned about whether a battery is safe enough to meet the demands of mod use when run in series, if we are concerned about a given amp draw, about the reliability and threshold of a given protection circuit for our uses, if we are concerned about reputable manufacturers, consistent and even remotely accurate specs, and well tested behavior and performance histories with a cell, then you pretty much have to stick with these batteries. outside of these you are talking about using balancing chargers, very specific atomizer models and resistances, maybe even some that haven't been made yet, restricting specific voltage use, and generally taking disparate, conflicting, and often incoherent information across the web or blindly trusting the cheap option, and putting a potential IED in your hand, up to your face, by your bedside, around your family, etc. again, i'm not against users doing what they will, and i understand that this will occur anyway, but as far as recommendations are concerned these battery sizes and manufacturers are the ones to give across the board until all other variables, not just mods, but atomizers, chargers, etc., can otherwise improve the safety and performance demands of the batteries we use. one or more of these variables is likely to always be wanting, and again it will be the battery that ultimately determines the extent of any given failure.
