Why anything other than Sony vtc4 18650 batteries?!

Good to hear because I have 2 coming on the way for my big nasty
, thanks for the input, now I just need to find an rda that's big enough to look right on it!
Efest 1600mAh 30A vs Sony VTC4 2100mAh 30A - YouTube This guy did one, they are nearly neck and neck with the vtc4 just barely ahead by an average of about .2 volts. Pretty identical, but this isn't really that thorough of a test, you need watt/time curves to really get an idea.
-Then again, there is a reason why sony is so successful
jk
Sorry wasn't sure if this could be safety too, but I had that thought I should've. Thank you
now I'll probably get more specific replies!
How do you stay sane? lol just kidding, drugs are bad, except for nicotine, alcohol, and caffeine
Don't know how to stay sane either.

My favorite test is to measure voltage after vaiping a measured quantity of e-liq. Results are quite repeatable and relevant. I like voltage drop tests also.
Probably. My FT VTC4 got returned to sender and I got refunded december 2013. I did manage to get FT VTC3 before HKP fiasco. I believe the VTC3 are real, they perform well driving supra ohm toppers; 20R and VTC4 beats VTC3 sub-ohm and supra-ohm. I won't look to buy VTC3 again even though they are decent. BTW I have 2 FT 20R on the way; looks like they already left Asia so maybe they will find my mail box.
IMO a 0.2 volt difference can be pretty significant to your vape time per charge depending on where it happens and at what load. When comparing good batteries in the same class with each other you generally don't get more difference than that.
On another note - the best way to test a battery is in a PV - real time IN THE FIELD. I dont pay much attention to test graphs, batts perform differently with diff. set ups
The VTC5 renders this question moot, but prior to the VTC5 this was a, if not The, reason:
For 20A applications and below the LG HE2 performed as well or better.
That's interesting, they list the LG HE2 as Li-poly?
Have you seen any data on the VTC5 yet?
I'm not sure I understand why the batteries are called lipoly there, but as far as I can tell those are actual test curves. Could be the device won't test at 20A without setting to li-poly.
I have seen some VTC5 curves from a China supplier. They appear to be better than the VTC4s across the board, and a touch better than the LG HE2 at 10A and increasing as you go up. Very close at 10A and under.
Here's a datasheet I got just now: https://www.dropbox.com/s/7eg85sg5s8yzy8b/Technical Information US18650VTC5 Rev.0.2 26.05.2013.pdf
I purchased 2 vtc4s from my B&M.. After first charge I noticed what looked like liquid under the green sleeve, I called and asked about it. They said it was adhesive and not to worry.. The battery works fine, no heating. Anyone else seen this?
