heh thanks devilfishphil =)
Usually I don't like giving out stats of stuff before I actually get the items and test them out myself but since the number are already out and some of them plain actually wrong, I think i need to clarify a few things about this
mod:
As far as i know it uses a Buck Pulse Width Modulator
Stepdown Voltage Regulator unlike the lavatube which was a step up regulator. Meaning that:
a 16650 battery rated at 2100mah will not be a variable voltage since its a step down regulator. The only option you have with a 16650 battery is the "ego mode" which is 3.7v
with 2 16340 700mah
batteries to make it a variable voltage. with this you have 3 voltage options:
Green Color 4V
Orange Color 4.5V
Red Color 5V
Pretty much means that the EVO has 4 voltage options if your willing to switch out batteries and 3 voltage options if you use 2x 700mah batteries.
Now the battery capacity given by loongtotem for 2 16350 batteries in a EVO of 1400mah is plain wrong, someone correct me if i'm wrong but i'm pretty sure in a series connection which is what the 2 16350s are the voltage is double but capacity remains the same. Meaning that even with 2 163500 700mah batteries your total capacity is still 700mah but at 7.4 nominal volt ( its higher when fully charged but we will just got with nominal for now). the pulse modulation thou from what I heard does help into giving it a respectable duration per charge thou.
So again:
1 16650 battery = 3.7v no VV options, 2100 mah capacity
2 16350 battery = VV option of 4v, 4.5v , 5v options , 700mah capacity
a better review of this mod is from phil
enjoy!
