Has anyone tested the two against each other? I'm assuming that the VTC5 is most likely superior.
Efest 35A Vs VTC5?

The Sony is 30A max continuous draw, where the Efest is 35A pulse. I've never been too keen on Efest. They tend to overstate their specs. I have some if the VTC5s, and after a couple of days use, I am thoroughly impressed.
i agree with the sony. i have efest 10A and they are fine for what i do with a vamo v5 max 5A draw. i have sony's ordered for a mech mod. the sony's are long time proven to be dependable and long lasting. don't be fooled by the mah ratings the sony's will still last longer. or get one of each and let us know. welcome to ecf!
I've only used Efests in the 14500 and 18350 size, and not been impressed. They're currently out of my battery rotation. I also believe Efest exagerates their specs. I use AW IMR batteries almost exclusively.
Spec-wise the Sony us18650vtc5 2600 mAh 30A and the Efest 2500 mAh 35 amp are close enough that I'd go with the Sony's with the better reputation as an industry leader.

Personally I would like to see a comparison between the VTC5 and the Orbtronic SX30.
What's the source for the Efests being 35A pulse rather than continuous? I haven't seen anything conclusive in that regard.

Yup. Pretty sure they're rebranded LG. I wish folks would stop advertising with anything but MCD. It is misleading to say the least.

I have the efest 35a right now, i've been pretty impressed with the battery life, i just ordered a pair of vtc5's off of ebay today. I'm interested to see how well they work since i have yet to try any of the vtc series.
I'm going to vote Sony. Just got em today. They were drained though. Took almost 4 hours to charge on Ic i4.
Sony had higher voltage longer and stronger mid-range than LG. Probable not broke in yet.

I don't think that it's been established that these are rebranded LGs. Also, the LGs in question are ICRs, right? Or hybrids close to ICR chemistry? It would seem odd that a battery seller as well known as Efest would label their batteries as IMR if they indeed weren't. I've also found no conclusive information on Efest NOT manufacturing their own batteries, so perhaps they do. My only point is that we shouldn't make absolute statements before we know with absolute certainty. Until then we're only guessing.
EDIT: checked the specs at a battery vendor I trust (they only sell batteries and battery related items, provide more information than any other place I've seen, and appear to be very knowledgeable). They have the Efests down as stated capacity 2500 mAh, minimum capacity 2400 mAh, and c-rating 14 (which adds up to an amp limit of 33.6-35). Also, from the specs I've seen there seems to be a slight difference in the reported dimensions of the Efests and the LGs, although so slight that it simply might be due to measuring errors.

VTCx are the most widely used/trusted batteries for a reason.

VTC5s all the way. A pulse rating being touted as the actual amp draw is misleading at best. I prefer a battery that does what it is supposed to all the time.
Just received my vtc5's today, and after comparing the two freshly off the charger i can conclude that the vtc5's blow the efest 35a out of the water. That's not to say that the efest 35a aren't great batteries, the vtc5's are just better.
Mine came today and they are charging right now, can't wait to see how much better they perform than my AW IMR's. What specifically did you notice in practical use difference between the Sony's and the Efest?
vape mail came today with two vtc3s and contact pin for my kayfun. built a 1.4ohm coil for the kayfun. tried it on a vamo v5 and switched to a mech mod(no pulsing) with a fresh efest 10a. good vape but performance lagged in a short while. the sonys were charging so slow i turned the charger up to 1amp. man what a difference the sonys make. it hits instantly and after three hours of enjoying the kayfun there are still 3.9v available. the efest fell to that level in one hour. considering only 1600mah sony vs. 2250mah efest, i will buy more sonys. do all efest pulse power? first knowledge of this i have read.
I've never used AW imr's but i'm sure you'll notice a difference. I don't have one of those devices that measure voltage under load, but it looks to me like the vtc5's have a significantly less voltage drop. My .8 ohm dual micro coil set up was defiantly producing more vapor with the vtc5's as opposed to the efest 35a.
Like with the general consensus, I have to go with the VTC5. The 35A from what I was told is a pulse rating, and the Sony just gives me that unconscious sense of security. Not the most scientific of analysis, but that inert safety just pushes me towards the Sony.
