4-5 hours sounds good. I drain my 510 battery in about 1 hour or less.
I've pretty much been hooked on 6V since I got the S6, so my 14500s stay in my e-smoking bag most of the time. I've been getting 2 to 3 hours on the UltraFire unprotected CR2's and around 2 hours on the Excellerator LiFePO4 CR2's.
Jeff, I've experienced the vapor fall off like you've talked about on my super mini I use to vape. The CR2's seem to hold up pretty good though. The start off at 3.6-3.8 volts and stay over 3.2 most of the time. At the end they seem to drop to the 2.8 to 3.0 volt range and that's when I change them as the vapor production really drops off.
Jeff, I don't have near the experience as you do with PV's. I am happy though with the vapor production on the S6 with the dual CR2's. It may be that I came from a super mini and the vapor drops off really quick on those. What I tried of the 14500's I was very happy, the 6V just gives me that extra throat hit I like and I get nice consistent vapor production for several hours.
Thanks,
David
Are you talking about the LifePo4's?
Beware of them as I have read that some Chinese distributors are actually selling fake LifePo4's that are really CR2's in disguise...
If you want to use CR2's then make sure you get the GREEN ones.... From all I have read it's the BLUE CR2's that are at issue...
I think the LifePo4's would be a good option if you get them from a reputable source... If not, you'd be rolling the dice that they are re-branded and junk blue CR2's in disguise...
I mean call me Stupid Ignorant Or Just a plain out ........ So what is the point of a HV atty????A regular 510 runs at 2.2-2.3 ohms so you do the math. If you use a 5.2ohm 510 you better be pushing like 8v to get a decent hit imo.
