How low can you go
« on: January 06, 2014, 03:35:08 PM »
Found this chart today

It will give you a rough idea of how low your coils resistance can safely (if coiled correctly) go depending on what batteries you are using.

that is a horrible chart.... all those numbers are way off.. did you find the right numbers and then take 25 percent from those and then post it?  Or did you just copy this from somewhere, cuz that chart is way off my man. I get ur trying to keep people safe, but the numbers are not even in the ballpark.  Imo its best to tell real numbers and then tell people it is advisable to have a little cusion.  again dont take this the wrong way im not attacking you im attacking the chart.

So help us out here -- which numbers are way off, how can you tell, and do you have a more accurate chart or link?

Not my chart, but have not seen any complaints anywhere about it

If it is wrong, at least state what is wrong

I think he is trying to say the resistance is not the absolute lowest you can go to max out the amperage rating on a battery. Nothing wrong with the chart. It is probaby the safest guideline with respect to having a good vape and keeping batteries healthy. With that said, this isnt the chart for cloudies..

That's fine

If your a cloud chaser, then you wouldn't look at this chart

Too many new guys wanna blow clouds, if the numbers are wrong in a good way then that's fine by me.

It was put here as a guide line for new chasers, the more experienced would have done their homework already.

dorry i didnt get back to ya sooner i dont go on much... the problem i have with the chart is that most all the amp ratings are incorrect, i dont have a chart to back it up.... but being a mechanical user and a bit of a battery nerd i know my batts and amp ratings.  You could argue its good that the chart doesnt say the higher ratings to keep people safe but i feel it is beter to tell the true numbers with a warning of caution.  I guess this is a noob ref chart and not an experianced users chart, I dont really mind i think its a great chart to go by if ur new into subohming but this def isnt the ref chart a more seasoned vaper would glance at.

Thanks for clearing up your objections, S_P_A.  :)+1

With batteries having pulse and continuous discharge amp ratings, things might get confusing for the new sub-ohm vaper.

Doesn't help things when I saw two nearly identical batteries in a shop the other day, but they had different mAh and amp ratings.

the green sonys have that problem everyone sees a green sony and thinks they are 30 amps, but there are green sonys that are nowhere near that rating and they look exactly the same i think the tag is sony us18650v or vt and the real high amp ones are us18650vtc3, 4 ,5, but the numbering isnt clearly visible on them and the numbers fade pretty fast.  There are some of the less powerful sonys coming out of laptop batts and are being sold on ebay to noobs who think they are getting one of the most powerful batts out.  needless to say there can be some dangers throwing those batts in a .2 and slamming that button down.

I have batteries that aren't even on the list. I have some Efest purple 18650 2500mah that say 35amp on the battery. Would like to know if they are truly 35amp though.

Thanks for the link Dan. As a newbie to Mechs(very soon) I want to be as safe as possible. I would rather have a chart that keeps things on the safe side, than have a chart for the absolute limits of a battery.

You're welcome mate

TBH

If you get some efest 35amp or VTC5's 30amp

You'll have a hard job coming close to the limits

I currently have a few 18650's,  Efest IMR 2000mAh. Any links to a decent site for battery's. I'm wary of buying them from Ebay, although if you(or anyone else) knows a reputable seller, that would be great.....

That's my go to reference chart!

Makes me nervous that vapers could potentially be doing something like a .3 on an 18350 battery.

Really glad I found this! Or, that you found this! Either way, I' very pleased. My battery was listed, and this info may have just saved me a lot of hassle. I wanted to do a vertical coil build on my Plume Veil. I use the LG 2500 mAh mentioned near the bottom. I made the coils using 4 strands of twisted 30 ga wire. i use my Vamo to get a rough reading. it's close enough for my purposes. I came in at 0.3 ohm, which means i'm likely between .3 and .4, which is below the recommended limit. i had noticed the mod heating up, which it usually doesn't do. the battery was warm when I took it out, and i wasn't even vaping with it yet. I had simply started the process of tightening the coils up to get them closer together. I'll judt remove one and run at around .8. I'm not competing with anyone or trying to push limits with my gear. One of them was .8, I think, so I'll just run with one coil, and be content and safe. Thanks for posting this way back when, before I even had started vaping! lol

Seriously....great info! 8)

I'm glad you read it

And of course, found some use from it

Safety is of the upmost importance and something we are constantly telling people so
