Who cares seems he likes to fak about.
I was just trying to help people be cautious of anything that is too good to be true. I've been using mine with no problem in the 20 watt range, but I'll probably be getting some sonys as well next week.
Need help from former MFS (MyFreedomSmokes) customers
Has any found a supplier or company that has tobacco e-juice like or very similar to MFS Turbosmog, Tall Paul, or Red Luck?

You can surely draw your own conclusions from your own research, I drew my own conclusions from personal testing and experience rather than letting someone with unverified information that was taken from the internet "tell me" what I should find out for my own self. There are a decent number of people using these batteries with GOOD results, I think they are a good battery. As more information comes forward on them I am sure many others may make the transition to using these cells, as they provide a good quality longer lasting vape IMO.
Thank you for you post and sharing your test results! This ^ is exactly what my previous post was about.
Very helpful, thank you.As far as these batteries being "re-branded" or anything I'm not sure of the exact information on that, so take this information with a grain of salt. I feel it is fair to note that I am just an experienced user, I am in no way affiliated with ANY company that produces ANY products for the vaping community.
Long time lurker, felt the need to post a comparison and a bit of info I've gathered on these Efest batteries. For starters, I'm lucky enough to live near a very well stocked B&M vape lounge, last week I was informed that they would be receiving these Efest 35A 2500mah batteries. They got their order in about mid week this week and within the first 24 hours had sold 100+ of the batteries. The owner/manager of the shop personally uses these batteries and likes them a good bit. Since they started selling them they sold out of their order in under three days, which from what I've gathered was over 250 batteries. Not a single one of them has come back yet, and most of the people I've been talking to that use them have had very good results.
Several of the people that frequent the shop were users of AW IMR 18650 or Sony VTC4's, the general consensus is that they're much longer lasting than the AW's and that they're right on par with the Sony VTC4. Personally I don't much like to take others word for it so I bought two of the Efest 2500mah 35A 18650's to do my own little test against my battery of choice
First, I wanted something that was a known good performer to test them against. In come my old reliable batteries as a comparison, MNKE 18650 1500mah 20A - which have been performing very well for me with my .52 ohm build.
Setup that I "tested" the batteries on was this mod: Smoktech Natural, 18650 mode - Pyrex RSST with a twisted 26ga 5/4 coil at .52 ohms, drawing ~34 watts at 4.2v and ~27 watts at 3.8v. This exact mod with this exact coil was used for both batteries and all tests, no changes were made.

Here's my little test. Fully charged both batteries, the MNKE and Efest. Both are right around 4.20v coming off my charger(Xtar MC1). Efest metered out at 4.21 right off the charger and the MNKE came in at 4.20 right off the charger, ALL measurements done during my "test" were done with a High quality ES-597 Digital Infrared Multimeter, including using it to measure my coil and all voltage drop.
Here's a picture of the batteries that are going up side by side, measured and assured to be fully charged.

First test:
- Charge time after first full charge and drained to 3.70v, charged from 3.70 to ~4.20 (we all know some batteries can really take a while to do their first charge) - Charger used was Xtar MC1
- MNKE: 2hrs 11 minutes
- Efest: 2hrs 35 minutes
Second test:
- LOADED voltage drop, both batteries at ~4.20v, initial starting voltage will be recorded and noted. These were both fired on a Smoktech RSST on top of my Smoktech Natural mod with a .52 ohm coil in it, due to the nature of the coil and the load it goes through I believe this should be a decent test. Draw is ~8.0A continuous and providing ~34watts to the coil.
- MNKE:
Start voltage: 4.20v
LOADED voltage at 5s firing across .52ohm coil: 3.51v (overall drop .69v)
- Efest:
Start voltage: 4.21v
LOADED voltage at 5s firing across .52ohm coil: 3.57v (overall drop .64v)
Now, remember those are both on the exact same device, same coil, nothing messed with or touched. ALSO please keep in mind that the higher the draw on the battery the more drop you will see, so with a .52 ohm coil having a ~.6v Drop is perfectly acceptable. My mod vapes very well at .52 ohm and I am very happy with these numbers, from BOTH batteries. The difference you are seeing between .69v and .64v is down to the internal battery resistance, all other factors are identical during the test.
Third and final test:
- I wanted to do a longer test, something that I could measure voltage after and really evaluate the overall vape experience between the two batteries. So, I filled my RSST with 3ml of 50/50 juice measured in a syringe and threw in each of the batteries. Vaped the entire 3ml tank at .52 ohm over a period of ~2 hours with each battery.
Starting voltage:
MNKE - 4.20v
Efest - 4.21V
After installing each battery and going through 3ml of juice over the same ~2hr period of time I pulled each battery and measured the remaining voltage, I also logged in my head how pleasurable the vape experience was and if I noticed anything different or similar between the two batteries.
ENDING voltage, 3ml 50/50 juice vaped through Smoktech RSST @ .52ohm
MNKE - 3.59v - Definitely noticed some drop off at about the last 1ml, it needed to be charged right away. About the last .5ml of liquid I noticed the firing button on my mod was starting to get warm, which is generally a sign that I need to swap batteries.
Efest - 3.78v - Did not actually notice any real drop off, was able to vape the entire 3ml tank and then switch over to my dual coil .50 ohm dripper and vape another full 1ml without any notice of dropping performance, when I removed the battery and measured it even after use with my dripper it was still at 3.68v. Firing button never once got hot or warm.
Final wrap up:
- Personally, I've done enough of a thorough test that I believe the Efest 2500mah 35a battery is a good choice, it provides MUCH longer life for me with sub-ohm builds and doesn't drop voltage as fast as known good performers. I will be using the Efest 2500mah 35A batteries for a while to come. Personally, I don't ever build coils that draw over 20A so I don't worry about the true Amp output of these cells, it may very well be 20A and it also may very well be 35A. Until someone with verified information comes forward to note the true maximum current capacity of these cells I would advise a bit of the usual "caution".

These are NOT 35A batteries.
Be careful, and vape safe.
