fishguy1123 Posted January 20, 2015 Share Posted January 20, 2015 I've never heard of smurf batts. Where did you get it? Link to comment Share on other sites More sharing options...

Tug Posted January 20, 2015 Share Posted January 20, 2015 I have the same battery.its a good one. Mtdobies 1 Link to comment Share on other sites More sharing options...
coreykmk420 Posted January 21, 2015 Author Share Posted January 21, 2015 whats the lowest ohm you have went to with no trouble Link to comment Share on other sites More sharing options...
fishguy1123 Posted January 21, 2015 Share Posted January 21, 2015 Ahh... the 25r, I'd say you should be ok. I'm guessing you already know ohms law and batt safety. The 25r's seem to have a good rep these days from what I've heard. Link to comment Share on other sites More sharing options...
coreykmk420 Posted January 21, 2015 Author Share Posted January 21, 2015 not to well im still fairly new to it ive been researching it for days now and im having trouble understanding some of it mainly how to tell how to sub ohm safely ive been cautious and ive checked my battery for heat and stuff it seems to be fine Link to comment Share on other sites More sharing options...
fishguy1123 Posted January 21, 2015 Share Posted January 21, 2015 whats the lowest ohm you have went to with no trouble IMO, the correct answer is nothing lower than the specs allow, and you should never push a batt to the point it causes trouble. If someone chooses to push things to the edge, they may find themselves falling off the cliff. lol Link to comment Share on other sites More sharing options...
Tug Posted January 21, 2015 Share Posted January 21, 2015 I don't go below 0.3ohm because I don't feel the need.So I really don't know. Link to comment Share on other sites More sharing options...

Steam-engine.org or an ohms law calc for android phones are a good place to start for calculators. How do you test the resistance of your coils?

coreykmk420 Posted January 21, 2015 Author Share Posted January 21, 2015 i use the meters sold at vape shops Link to comment Share on other sites More sharing options...
fishguy1123 Posted January 21, 2015 Share Posted January 21, 2015 Good, check out those sites. When you plug in the info in each category they can be easy to use. May I ask what your looking for in the super sub ohm level to get a good vape? Link to comment Share on other sites More sharing options...
joejoevapekins Posted January 21, 2015 Share Posted January 21, 2015 .2 is cutting it close on the 25r. Only rated for 20A. On a fresh build it puts you right at 21A and 88watts. Once it drain a bit its fine. Remember as voltage changes the amp load will change. Tam 1 Link to comment Share on other sites More sharing options...
Earthling789 Posted January 21, 2015 Share Posted January 21, 2015 ^^ This ^^ I was about to chime in that the 25r's were 20A rated. I would not use them for anything lower than 0.25 Ohm builds, just to be under the Amp-threshold. I think they will operate slightly higher than 20A, safely, but I'd rather not find out "the hard way"! joejoevapekins, mvince201 and Tam 3 Link to comment Share on other sites More sharing options...
vaping_jake Posted January 21, 2015 Share Posted January 21, 2015 WOW!!! I didn't realize people were looking at <0.2 resistance. Is there some chicken game I am not aware of.. how close to a short can u get...JK!! Hmm maybe a patent for a super conductive atty is in need.

Mtdobies Posted January 23, 2015 Share Posted January 23, 2015 Specs on the 25r are for continuous drain such as a flashlight. Remember these are "SAFE CHEMISTRY" batteries which means they don't "blow up" as people seem to believe or can't get it out of their head anyway. I personally have used these batteries quite frequently at super sub ohm being responsible and checking the charge on the batteries not letting them get below 3.6 before recharging. Just because I don't want the batteries too drained, not for fear of anything getting hot. Safety is always best and depending on the RDA and Mod your using its all a factor you can get nice clouds at a .2-.3 vape all day, I'm not saying chain vaping as that will strain your 25r or any battery, but regular vaping at .15 a 25r will last me all day. Specs are Not considered on a battery for pulse vaping. Its the lack of practical application actual use of these batteries and such that feeds big tobaccos agenda imo. That being said if we are going express a opinion perhaps it should be a bit more researched. Safety is always first ohm meters well charged batteries, maintain your equipment. In light of the new testing going on ATM to be on the safe side I would suggest staying at .2 or above perhaps until we figured out the formaldehyde reality. That would certainly be more realistic a concern then the improbability of a battery having problems but you want to be aware as I said of your charge of your battery to maintain its life. Congrats on no smoking. mvince201 and joejoevapekins 2 Link to comment Share on other sites More sharing options...
