New to ECF not new to vaping Nice to be here :)

[ggivens117]

So I've been a long time lurker on ECF as you guys pop up when I do any kind of search on vape info and usually you have pretty good info today I was looking for battery info and as Im not really the sharpest tool in the shed I've been able to identify batteries I'd like to know more about but cannot understand half of the info I find but then I found an old blog by rolygate regarding safe batteries and battery practices but alot of it was written in a fashion i didnt quite understand. So I'm looking for this rolygate person or some other battery guru who can talk to me about Li-fePO4 batteries and other safe high drain high power batteries for sub-ohming anywhere around .25 - .15 because as I'm sure is true for all of us I'd like to vape without blowing up

Hello and welcome to the forum. Glad to have you here!

Don't know if you are interested in mech mods/rebuildables or regulated mods/rebuildables so I'll give you the complete package of links.

I highly recommend you spend some time with Baditude (one of our resident battery experts) and visit his blogs. With mech mods you will be 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries. If you are going to be using a regulated mod you may not need all of the above, but an ohm reader will come in handy.

Baditudes Blogs. The blogs regarding mods and rebuildables are listed below:

BATTERIES

9. Battery Basics for Mods: IMR or Protected ICR?
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.

17. Purple Efest Batteries Not As Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.

OHM'S LAW

14. Ohm's Law for Dummies (Vapers)
* My attempt at explaining Ohm's Law in layman terms and how it relates to vaping.

16. Explain it to the Dumb Noob: Ohm's Law Calculations
* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.

MECHANICAL MODS & REBUILDABLES

7. Information Resources for Your First RBA
* An essential read and reference guide for someone new to rebuilding coils. Includes a multitude of useful links on battery safety, mod safety, coil meters, coil building, and the differences in the three types of RBA's.

15. Inexpensive Mechanical Mod and RDA Setup
* A response to the frequently asked question on how to get into rebuildable atomizers with a mechanical mod inexpensively. Includes a list of commonly used tools and supplies for rebuilding and where to find them.

BATTERIES - WHERE TO BUY

Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.

* RTD Vapor
* Illumination Supply
* Lighthound
* Orbtronics

You've got the info on safe batteries so I will just say hello and welcome to the ECF family.

Happy vaping

 

[Harlen]

Hello and welcome
Vape on

 

[daleron]

Welcome to ECF ggivens, make yourself right at home

 

[joesquid]

Welcome to ECF! Glad to have you aboard. Check out the links Susan posted. Should answer all your questions.

 

[SinisterSilver]

Looks like Susan took care of you pretty well, so welcome! Glad to have you here

 

[Frenchfry1942]

Welcome!! Glad you are here!

 

[ggivens117]

Thanks for the welcome guys and I guess I should've been a little more specific and said that I'm running An unregulated mechanical mod and want to know specifically about these Li-fePO4 batteries as they have an extremely high discharge rating but
With 70A at continuous but also sit at only 3.2 V

Can you provide some info on your specific batteries? In order to get meaningful feedback on what you're using, we need to know . . . well . . . what you're using ;-)

I am not overly familiar with LiFePo4 batteries. My only experience with them are the old CR2 sized ones that vapers used to stack for 6V vaping back in the day . . . those particular batteries were not well-suited for the application, though, as they had a very low max discharge rate (only 1 or 2 C, depending on the particular model). They were responsible for at least one high profile e-cig explosion a couple years ago and probably more beyond that one.

If you have something of that chemistry that is actually capable of handling vaping, I'm sure others will be interested in it

 

[ggivens117]

Well I'm not using them as of yet just saw them a few days ago on a post and was wondering if anyone knew about them I'll do some hunting and see if I can find the link for ya as I can see why that would be necessary

They are A123 Li-fePO4 26650 batteries they can be found on battery space or you could just Google that name I gave they read as a nominal discharge 3.2v battery with 60A continuous and a 120A pulse rating i'd love to know if this type of battery chemistry is safe

 

[DreamWithin]

Is this the battery? A123 System High Power Nanophosphate LiFePO4 26650 Rechargeable Cell: 3.2V 2500 mAh, 120A Rate, 8.0Wh

I'm not overly familiar with these, myself. I am a little confused about the high drain rates on this model, while other 26650 batts in this chemistry appear to be only a ~3C discharge rate (considerably lower than the 28C listed for this battery)

You're one post away from being able to post in other forums than New Members. Once you've made your 5th post, the server will update your permission set within an hour (at 0:25 past the hour is when it updates). I want to move this thread to the Batteries & Chargers forum where it will get more visibility for those who know more about batteries, but I'll hold off on moving this thread for the moment since you wouldn't be able to post there just yet

 

[ggivens117]

YES thats exactly it and I'd love to move this to the battery thread because I want to know if I should buy these hahah

 

[ggivens117]

but I'll hold off on moving this thread for the moment since you wouldn't be able to post there just yet

lol can we move it now

 

[DreamWithin]

Sorry missed your post and just noticed I still had this thread in my subscriptions. Apologies for the late response

Moved to Batteries & Chargers from New Members

Hi ggivens and welcome to ECF. I did some research on Li-fePO4 cells a while back. They are quite safe, take much more overcharge than IMR or hybrid Li-ion, max volts off a proper charge is 3.65v so you get 87% the power (watts) per amp compared to 4.2v. 70 amps continuous would still be very nice

I am skeptical about the 70A continuous and 120A, 10 sec pulse rating. I found the battery at the manufacturer's website and they don't give amp ratings. There is an option to download a data sheet, but they want information about you and your application which I didn't fill out.

I don't remember these cells being this high power the last time I looked at them. I suspect the numbers are exaggerated, but I don't know for sure. It would be very interesting if the numbers were accurate.

 

[Ryedan]

So I'm looking for this rolygate person or some other battery guru who can talk to me about Li-fePO4 batteries and other safe high drain high power batteries for sub-ohming anywhere around .25 - .15 because as I'm sure is true for all of us I'd like to vape without blowing up

I'm comfortable using LG HE2 18650 20A, or Samsung 25R 18650, 20A down to 0.25 ohms at 4.2v which draws 16.8A. I've taken these batteries down to 0.18 ohms, 23A with no sign of heating up, but they are new cells and I would not vape that way all the time. It's not IMO a safe practise and as they get older their internal resistance will go up and their max amp rating down.

For my all day vape setup at around 0.3 ohms I use the HE2 and 25R. For the 0.18 ohm setup I use Sony VTC, 30A cells.

If any of these batteries would hard short I expect them not to explode, but rather vent without flame. I am not going to try it though. A few times, one of these type of batteries has apparently exploded so it is possible if things go badly wrong.
