The atty I'm using works on my other Pv...still could be the center post thingy thought right?
I have no idea how to tweek the post on it....
yeah, it probably is the center post...the atties i got in my e-power kit that dont work with the e-power work on Ego batts...

Looks like it is regulated, just not the same way an eGo is

Your battery might just be crap.. the higher internal resistance of a battery the greater the voltage will drop under a load. I have done quite a few tests with my 14650 e-power and the stock 14650 batteries that come with it BLOW in terms of maintaining voltage.. I think SmokTech used some surplus cells or something, because they are of terrible quality (at least the ones I have).. Here are my loaded/unloaded test results for my 14650 E-Power with stock batteries AND with AW IMR 14500s (Custom spacer)

STOCK 14650 battery, open circuit voltage: 4.02
STOCK 14650 battery, wired directly to 2.0ohm carto: 3.35
STOCK 14650 battery, wired directly to 3.0ohm carto: 3.52
E-power voltage, no load: 4.01
E-power voltage, 2.0 ohm load: 3.33
E-power voltage, 3.0 ohm load: 3.48

***AW 14500 IMR Test results
open circuit battery: 4.22v
e-power(with 14500 IMR), no load: 4.21v
e-power(with 14500 IMR), 3.0 ohm load: 3.97v
e-power(with 14500IMR), 2.0 ohm load: 3.88v

As you can see, the e-power outputs just about the exact same (tiny tiny bit less) as wiring the 14650 battery directly to the carto. There does not appear to be any regulation (with my switch).. just a really really crappy battery that makes it look like there's regulation because it drops so much under load. You'll notice that the e-power 3.88v with a 14500 AW IMR battery and a 2.0ohm load...

Yes, Thats exactally what its doing..wala

You could always pull the center post out, glue it with superglue and lightly attach the cartos back on it? Sounds like a recipe for inhaling glue unintenionally and would taste like crap....not sure what else to do. Sounds like it's cheaply made :/

The battery seems to have issues with placement. When the charger tells me the stock battery is fully charged, I can twist it a little and the light turns from green to red. I'm guessing that metal tab on the positive side of the battery is causing extra resistance or a poor connection.
