vaporraper Posted January 22, 2014 Posted January 22, 2014 So ive ben vaping now for about two months and like most things that i get into i gata go full throtel.. i recently started to venture into sub-ohm and i no that i should respect it and deff pay atention to ALL the do's and dont's.. Ive got the 30 amp sony's otw and have a e fest 30 amper now..of corse i have an ohm reader for this and realy want to b as safe as i can!! I know that stressing bateries is probably the main thing i should try and avoid and id like to pick up a mutimeter to see whats the bat voltage before and after i use it.. So anyway,i guess im asking for your opinion's on safety mainly and any other things that could be important to know.. Thanks for the help VT...You guys rock!!!!!!!!!!!!!!!
WillBlack Posted January 22, 2014 Posted January 22, 2014 From the one, very underwhelming test of the Sony US18650VTC3 vs the Efest 30A I'd say the Efest is also just a re-wrapped Sony. Efest makes but also re labels many cells, the mAh is often the clue. Can you guess whats under the hood? Efest 18650 3100mAh Efest 18650 3400mAh Li-ion Efest IMR 18650 2250mAh Efest 18650 2600mah The first 3 are are Panasonic and the last a Sanyo. Take a look at my Sony test post. The now ignored AW IMR18650/1600mAh, (Mr AW rates them at 15C - 24A) will also totally embarrass the Sony US18650VTC3. Anyone doing high drain comparison tests should always compare them to the original beast.
Joshuab3687 Posted January 22, 2014 Posted January 22, 2014 Will, So, you're saying the best bet to go with is aw imr 18650/1600 mah? Just wondering because I already ordered 2 Black Efest 18650/2250 mah flat-tops. I know they're just rewrapped Panasonics. Did I do bad, good, or meh?
VapeEscape Posted January 22, 2014 Posted January 22, 2014 I've been doing some sub ohming for quite awhile now. my only suggestion is to never go below 0.3 ohms. i know its safe with a 30 amp battery but its just my own personal advice. make sure you have PLENTY of airflow to the coils or they will just get too hot to vape. and i get my batteries from bevapehappy.com if you are interested. they have 15 amp and 30 amp batteries. vaporraper 1
vaporraper Posted January 22, 2014 Author Posted January 22, 2014 Thaks VapeEscape!! I was thinking .2 might b limit but why push harder than nessisary..

In that mAh CLASS like the Sony US18650VTC3 or the 2nd tier MNKE (another cell with fancy specs) the AW1600mAh is the best choice. Too expensive though. In general these 2000mAh cells are the best high drains and are what I would recommend, for the sub ohm crowd. Great price too. 2x-Samsung-SDI-18650-20R-INR18650-20R-2000mah The ones you got are not really ideal for sub ohming. Here's a 7A test, I'll call it about equivalent to a .5Ω atty, BTW I compared it the Callie's 2250 (Panasonic) the traces are identical. Useable, but the Samsung is the better choice. At 10A the gap widens considerable more.

qwikrex Posted January 23, 2014 Posted January 23, 2014 I'm running mnke 18650's in my sub ohm build. Might try out the sonys with the higher amp draw rating.
vaporraper Posted January 23, 2014 Author Posted January 23, 2014 I'm running mnke 18650's in my sub ohm build. Might try out the sonys with the higher amp draw rating. Dont know if its me or not but it seems like when i use the sony (c4) it almost has a burnt taste compeared to the 1600 mha high drain e-fest..gata keep vaping and find out..seems like the sony deff has power!! Running it on an igo-w with a half ohm coil.
GEFFiCART Posted January 23, 2014 Posted January 23, 2014 a burnt taste will not have anything to do with your battery. your battery just fires you set up, choosing the right battery will determine a safe circuit depending on the ohm's you'll run. you might have a burnt taste due to different reasons - you have a hot spot in your coil - you're pulling dry - your cotton got burnt [if you're using cotton that is] without a picture of your build or what you're doing, we cannot narrow why you have a burnt taste

It was just wierd cause when i put the sony in is when i noticed it..mabe it was just a dry hit or just my CRAZY TASTE BUDS?
Mrwaylon Posted January 23, 2014 Posted January 23, 2014 How long of pulls are you doing?. I know when I sub ohm and take long pulls it taste burnt. Plus your not chocking the coil are you? Meaning to much cotton make sure it's loose.
vaporraper Posted January 24, 2014 Author Posted January 24, 2014 Most of the time just 2 or 3 second rip's is enough but sometimes ill go for a super fogger..deff not making the cotton to tight,i always make sure that it goes back and forth with some resistance but not to tight.. It might just be that im not juicing it fast enough..not use to useing so much juice..subing deff goes threw it!!
Mrwaylon Posted January 24, 2014 Posted January 24, 2014 Yeah I've noticed to that some flavors when sub ohming taste burnt no matter how much juice you put on it.
spydre Posted January 24, 2014 Posted January 24, 2014 Yeah I've noticed to that some flavors when sub ohming taste burnt no matter how much juice you put on it. I think this COULD be because some flavors may not be able to take the temperatures that sub ohming at 3.7 volts puts out. At least, I know my 555 has problems on a 2.5 coil going much above 3.7 volts - it just doesn't like to get that warm, and tastes burned. Has ever since I started vaping the 555 from this supplier.
hookahhighness Posted January 24, 2014 Posted January 24, 2014 i just started in the dripping world with a k100 and a patriot clone atty, now i rebuilt the existing coil in it cuz well it sucked now its at a .4 ohm and burns beautifully ive been dripping my adv 555 from mt baker and the taste is GREAt. using ekowool and a flat ribbon kanthal (which im out of) so going to move onto a 28 gauge while my ribbon is in the mail.

Try twisting the two wires up together when u get more ribbin..sence i started useing it i havent used anything else!! What baterie you using for subing?? RobChase 1
VapingSteez Posted February 4, 2014 Posted February 4, 2014 I just did my first twisted dual coil today and WOW! Have I been missing out vapor production and flavor are amazing! It's at about .35 ohms which is pretty comfortable for me. I've gone below down to .21 but it's a bit of a pain in the you know what dripping every 2-3 hits. Much better with a twisted set up RobChase 1
VapingSteez Posted February 4, 2014 Posted February 4, 2014 Oh yeah I'm using 26 gauge kanthal and cotton wicks
Joshuab3687 Posted February 4, 2014 Posted February 4, 2014 I'm gonna try and twist up some 32g when I get home this w/e. RobChase 1
iheartvape Posted February 4, 2014 Posted February 4, 2014 i twisted 2 28g strands with some flat ribbon... holy hell, you wanna talk about a hot vape! RobChase 1
VapeEscape Posted February 11, 2014 Posted February 11, 2014 Thaks VapeEscape!! I was thinking .2 might b limit but why push harder than nessisary.. I've seen 0.25 builds but I won't do that lol I'm usually at 0.3
GEFFiCART Posted February 11, 2014 Posted February 11, 2014 I recently built a 0.3 octocoil if you can call it that each coil is 14 wraps nano around a 23g syringe split in half. kinda like a bunny coil but nano version basically 1 wire, two coils, 7 wraps each. I have 4 of those in my helios
Joshuab3687 Posted February 11, 2014 Posted February 11, 2014 Geff, can you post a pic of that? I'd like to give that one a try. How is it on flavor&vapor
GEFFiCART Posted February 11, 2014 Posted February 11, 2014 Geff, can you post a pic of that? I'd like to give that one a try. How is it on flavor&vapor how do I go about posting a picture without a URL? flavor is really nice, favor is okay im still getting used that that low of an ohm with the throat hit because I cant take pulls longer than a couple seconds. my lowest build before this was a 0.5 the build is so warm I don't know how I feel about it
