Of course, I hope you find a good number for you! 
Hi all GG boys (and girls)
That's it I ordered my first rebuildable, GG Pénélope V3.
A big thanks to Alessandro from Bitfumo for all his kindness.
At first it was for a mod 14500 which has just arrived on the market (with a naming refers to Greek mythologies), but 58 pages later, 1h30 Imeo video reviews, and Alessandro, convinced me to wait the Best a Protéus.
It will be my first Mod, my Pénélope must have to wait for it...
Until it I will involve to make coils and to use it on a poor eGo...
I'm very impatient!!!
congratulations for your purchase my new friend sale and welcome to GG forum
Alessandro is right. Dont spend your money to 14500 mechanical mods, they are useless. 14500 needs electronics to work right
Why do you preferred battery Button top, i however believe that the Efest 14500 flat top is more powerful ....
I use a lot of 14500 cells and the Efest 14500 flat top (= the V1) is the reference 14500 cell, outperforming all others by a large margin. Much better than Efest's own 14500 button tops (= V2) too. Various in depth battery test available online confirm this too. No other 14500 comes close to the Efest flat top V1.proteus cant be compared to any other 14500 mod to my opinion Sale. The removable electronic part, the way you can disassemble everything on it, the mechanical button that comes as easy as esterigon's one, the ability to work as a mech mod, the air control, the conductivity that proteus has with his very special spring loaded applications the automatically adjusted center post and especially the length of proteus and its electronic part made it a unique piece of a thin e-cig.
If you want to buy an electronic e-cig that doesnt have all or part of these things, you can buy a China one that is a fixed design and if it brakes you throw it to trush because it would be cheap
I am working on a battery too but it will take a very long time to be made. My engineer is really busy right now.
As for why I prefer button top batteries, its because that way we have reverse battery protection on Proteus

I would call it electromechanical mod, the first of its kind Sad![]()

I seems the question was hidden too much so... Will Proteus be able to use flat top batteries?

Really Stanley?...
Amazing. Most high quality 14500 cells are flat tops and the very best on 2 - 3A loads - Efest IMR V1 - are flat top. Certainly not the 'famous' AW cells in this format. Button top only will seriously limit battery choice. I don't understand.

I think if you use a magnet you will be able to use this battery.
I know. But I would like to understand the reason(s) behind this design choice.
Mechanical reverse battery protection.
