OK, I've been reading up on the prototype Resin Reos. So far the answers I've gotten are 1) Woodvil sized 18650 mods. 2) Top Deck Fire Button (uhg !) 3) Low Profile Only. Rob is now only offering the 'Classic' juice Wells in metals. (mostly for older customers who have a preference) 4) these Mods, as all newer Reos, will contain the Gold Plated (sub-ohm) Contacts. 5) These will also contain the new 510 Connectors 6) No Quantities, Price or Sale Date mentioned yet.

Numbers 2 and 3 are probably deal killers for me. Top Deck Fire Buttons are awkward on a mod that large, even for my long fingers. And I guess I am one of the 'old farts' who is gravitating back towards the Classic Grand / RM2.


Well, if you ever want another Classic Grand, you know where to find one. :)

I don't know if he's straying or expanding. There are those who Love the Woodvil (like me) but question it's durability (like me). I think Rob is trying to provide an alternative to the Classic Aluminum Grand that might be more durable. The Lower Profile for the newer RBA / tank market, the gold plated contacts that allow for sub-ohming and the Stainless Steel one-piece 510 Connectors are apparently permanent upgrades.


Add to that the fact that you can go completely Shagadelic with colour profiles when it comes to resin, and I think it's a brilliant move!

Thank you so much for your answer, along with the other answers from Dusty, and Bronze. I will put the batteries back on. I can't right now, because I am charging the iStick. I just got the MVP2 off from charging. Seems like I am always charging something. So these Efest 35A 2500 are going to read 4.2 when full? My regular Li-On batteries read 4.1-4.2 usually. But I thought maybe because this was a different type of battery, that it would just read 3.7 volts when fully charged. I am afraid that info was a little bit over my head. I have never seen a battery on there just sit there, when I first put it on. So I thought maybe it was fully charged, but reading a little low. When I spoke of using the multimeter, maybe I wasn't clear. I used that on another battery, NOT the Efest batteries. Maybe that was understood, but I wanted to mention it again, in case it was not clear.

I don't use the Fenix ARE-C2 that often. I have two knock off Chinese flashlights, and they use 18650 batteries. I also bought AA and AAA batteries too, that are rechargeable. I thought well, I'd rather be safe, than have to worry about running out of battery juice. It seems unless you pay pretty good, all of those battery chargers are not worthy of your money, nor time. If I get really desperate I have a hand crank battery charger. Now that thing would wear me out, but it would work, in an emergency.

I meant to answer some of your battery questions from last night... but got caught up with trying to see Comet Lovejoy and forgot :facepalm:

The batteries we typically use have what is referred to as a nominal voltage of 3.7v ... that isn't what it's voltage is when they are fully charged. It is their "middle" voltage charge they have... it is also referred to by some as their storage voltage since it's the voltage they are most stable at. When these batteries have a full charge... they should have 4.2v and no more ( charging beyond that is very hard on them and ends up limiting their potential lifespan ). When they are "empty... they still have about 3.2v of charge left in them but taking them down to that level is also hard on them... most recommend only taking one down to 3.4-3.5v at most.... the 3.4v equates to them having used 80% of their total capacity.

The capacity of a battery is listed in Amp Hour ( ah ) or Milli-Amp Hour ( mah ). 1 ah is equal to 1000 mah. If you use up 80% of the batteries capacity ( which would leave about 3.4v ) then with a 1000mah battery you will have used 800mah of it's total charge.

The amperage discharge rate for a battery is rated with a C rating. The C rating is based on the total capacity of the battery so a 1000mah battery with a 1C discharge rating can discharge at 1 amp ( ie 1000ma )... at a 2C rating it would be able to put out 2 amps of power. There is also a charge rate for the battery also using the C rating method. The discharge rating is usually much higher than the batteries charge rating. So knowing both the charge and discharge C rating is important but they still often don't tell us both ratings, I suspect for marketing reasons. Another marketing ploy we see is a battery just advertised at it's maximum burst amperage instead of its max constant discharge amperage... so watch out for this... it just means those types of batteries can put out that amperage for just a short while usually a few seconds at most.

Now let's put some of that info to use in an example battery... the new AW 18650 2200mah battery let's say. It's max constant amp output is 20a and it's max charge amperage is 2.2a ... that means the discharge rate is about 9C ( 2.2a x 9 ) and the max charge amperage is 1C ( 2.2a x 1 )

Most, but not all... batteries can be charged at 1C safely but if you don't know... don't exceed 500mah ( 1/2 A ) just to be safe.

My two, despite daily use and abuse, are still working great after a year. "They take a Scraping and keep on Vaping" :D
How many years have you had your now ?


I got mine in Jan 2011.. and it was used hard for around 2 years.

Thanks Bronze. Then they will read like my normal 18650 batteries then. I have not been using the 18650 battery that long. Just started when I got that charger. I have never used the high/fast drain 18650 batteries before, ever. I will check this all out when the iStick gets through charging. Now I am curious.

Yes, the spec on that efest battery is a 4.2 volt max charge (+/- .05 volts). So it should read between 4.15 - 4.25 when fully charged.

Tada! ErlPrinz refilled with minimal mess. Keeping the tank upright and filling quickly seems to be the difference.

I filled it about 3/4 full. When I closed it, covering the top fill holes and tightening down the drip tip, there was a good bit of seeping juice from the bottom. I hope that won't always be the case, but for now I'm calling it a victory.

That review was posted on the 29th of December, so it's old technology already. :D

And guess what...it looks like a kayfun. How many variants of the kayfun have we seen? Anyone can say anything they want about the kayfun and diss it all they want. The kayfun revolutionized vaping unlike any other atty. Just a fact of the matter.
