Squid Posted December 13, 2014 Share Posted December 13, 2014 Hello all I have been vapeing for about 5 years and have just gotten away from the pen cells. I recently picked up a Itaste VTR. I was wondering if anyone has removed the "protection" from one of the 18650 cells for flashlights for use in an ecig. I am curious because I see the protected cells advertised upwards of 5000mAh, while the unprotected cells seem to max out around 3400 and are much more expensive. The VTR will not accept a protected cell as they are too long. I was hopeing that someone has some info on this. Link to comment Share on other sites More sharing options...
Squid Posted December 13, 2014 Author Share Posted December 13, 2014 I just read the Battery guide posted here, and think I may be mis informed a bit on the cells. But the cells for my nitecore light are too long for the VTR, and they are supposedly 18650 cells. Link to comment Share on other sites More sharing options...
joejoevapekins Posted December 13, 2014 Share Posted December 13, 2014 The protected batteries a little longer due to the PCB or fuse that's one them. You should never tamper with battery. Invest in some Sony vtc4 or 5. Or the efest 30amp or 35amp 18650 purple in color. Also the LG is good check the c rating or amp limit. Another is the Samsung 25r. There is also mnke and aw imr that would work great for that device spydre 1 Link to comment Share on other sites More sharing options...
Earthling789 Posted December 13, 2014 Share Posted December 13, 2014 JoeJoe gave a good list of batteries, and I always trust Sony VTC4 and VTC5... but also don't forget the Panasonic 3400mAh as well... I have four that I rotate in my mechanical Mods, and I know several on here use them in their VTR's as well. Link to comment Share on other sites More sharing options...
joejoevapekins Posted December 13, 2014 Share Posted December 13, 2014 lol I totally forgot about the Panasonic battery. I still have one that I use from time to time on my 1.2ohm and higher builds. thing last forever. Link to comment Share on other sites More sharing options...
Tam Posted December 13, 2014 Share Posted December 13, 2014 I use Panasonic 18650 3400 mAh in my VTR. Like Earthling said, that thing lasts forever. Personally, I would only use the battery as is and wouldn't take the chance of something going wrong by trying to change a battery to make it fit.

Earthling789 Posted December 13, 2014 Share Posted December 13, 2014 I know the Nitecore batteries you're talking about... I use them in my flashlights too. Yes, they are "protected" with a PCB fuse, and are taller. I'd not even begin to try to modify those to remove the protection circuit. Just use those Nitecores for your flashlights (as they are intended for) and pick up some unprotected 18650's for the VTR The Panasonic 3400's are about the highest mAh you'll find for your VTR. BTW, Amazon has a four-pack of Panasonic for $38 right now (Prime shipping). The price fluctuates from time to time but generally in the $35-40 range for the four-pack Tam 1 Link to comment Share on other sites More sharing options...
Mplough Posted December 13, 2014 Share Posted December 13, 2014 Glad you guys posted this, I was just about to ask about Nitecore batteries. I was just on their website checking out their charger. Link to comment Share on other sites More sharing options...

The VTR will not accept a protected cell as they are too long. I was hopeing that someone has some info on this. There is no such thing as a 5000mAh 18650... period. A protection circuit (PCM) will significantly impact performance. An example: Total mAh means nothing to us, we need to look at vaping mAh. Note Panasonic bases their mAh at a 2.5V cutoff, in the test above using a 2.8V cutoff we see how it falls short of those claims. If we use a more realistic 3.2V, vaping cutoff the 3400mAh Panasonic only manages ~2000mAh, the protected version only gets ~1500mAh. jasonculp 1 Link to comment Share on other sites More sharing options...
Squid Posted December 13, 2014 Author Share Posted December 13, 2014 Thanks all for the replies. I was very hesitent to cut a cell open, that's why I asked. I did not relaize that Manufacturers were useing cut offs lower than 3.2v, I was under the imprssion that 3.2v was a standard. Link to comment Share on other sites More sharing options...
Earthling789 Posted December 13, 2014 Share Posted December 13, 2014 It's all a numbers game... Manufacturers can make any claims they want, and back up those claims with skewed/slanted data, because there are rarely standardized tests or standardized testing methods. It's up to us to read that data and levy the results against apples-to-apples comparisons. On the bright side, the Nitecore chargers are excellent and well-made. I have two of their i4 models and they are reliable work-horses. However, "individual results may vary" Link to comment Share on other sites More sharing options...

spydre Posted December 13, 2014 Share Posted December 13, 2014 Even IMR batteries work fine, they are just on "lower" end of mAH rating, at 2000. Which, considering the amount of battery life I go through on a given day, now that I have the Zmax, I'm considering upgrading to a higher rating. At least, I assume that will last me longer. Experts, am I right or wrong there? Link to comment Share on other sites More sharing options...
Mplough Posted December 14, 2014 Share Posted December 14, 2014 Efest purple, 35A are my go to batteries. I'm paying $13@ at the local B&M. I have looked online for cheaper but I am amazed at how many BAD vape shops there are. I hate Facebook but it has opened my eyes on some of these shops. Also, I see a trend in knock off batteries. Having had a Dell laptop catch fire on my lap 6 years ago, batteries are no something I'm willing to screw around with. Link to comment Share on other sites More sharing options...

Compenstine Posted December 15, 2014 Share Posted December 15, 2014 I would have warned you too... They got hot on a .5 build. I would trust it in my VTR but not a mech with less than a 1.0 ohm build. Link to comment Share on other sites More sharing options...
Mplough Posted December 15, 2014 Share Posted December 15, 2014 Mplough, can I ask the origin or your user name? When I see it, all I can think of is "Mr. Plow" from the Simpsons. Well you get a star by your name for pronouncing it correctly. Mplough is first initial, last name. It comes from the original English name Ploughman. My ancestors fought during the crusades with Richard the Lionheart. After coming to American they dropped the 'man' and became Plough. spydre and Compenstine 2 Link to comment Share on other sites More sharing options...

I did not relaize that Manufacturers were useing cut offs lower than 3.2v, I was under the imprssion that 3.2v was a standard. Actually LG with their HE2 drag them down to a 2V cutoff, as does MOLI for their mAh ratings. Even IMR batteries work fine, they are just on "lower" end of mAH rating, at 2000. Which, considering the amount of battery life I go through on a given day, now that I have the Zmax, I'm considering upgrading to a higher rating. At least, I assume that will last me longer. Experts, am I right or wrong there? Actually true/pure IMRs, LiMn2O4 ( or LMN) tap out at about 1600mAh. Efest purple, 35A are my go to batteries. I'm paying $13@ at the local B&M. I have looked online for cheaper but I am amazed at how many BAD vape shops there are. I hate Facebook but it has opened my eyes on some of these shops. Also, I see a trend in knock off batteries. Having had a Dell laptop catch fire on my lap 6 years ago, batteries are no something I'm willing to screw around with. Your '35A' Efests are LGHE2s which are listed in their datasheet as 20A continuous discharge batteries. Here's more Efest nonsense. 20A? Here's a test of the LGHE2 20A battery vs. the Efest Panasonic 3100 rewrap. Having had a Dell laptop catch fire on my lap 6 years ago, batteries are no something I'm willing to screw around with. Probably those were Sony 18650s. It was a major fiasco that affected Acer, Apple, Toshiba, Dell and any other poor saps who used Sony 18650s. Sony has had to recall (10+million) cells and also dispose of more tainted inventory (43 million) than all the other major manufacturers combined.
