Second Gen KR808d-1 battery questions.

[DangerousFat]

I know they're regulated to 3.7v, Pulse Width Modulated to be more precise, but what is the native voltage? Are they just your standard 4.2v batteries that are PWM'ed to 3.7v like eGos? I've heard they were 5v native batteries, but that would mean that internally, they'd have to be stacked and I've heard a lot of horror stories about stacked batteries. Are these a single cylinder cell like most e-cig batteries?

Also, why do the KR808's seem to outperform similar-sized 510's? They're nearly identical in diameter, but in every instance I can find of comparable battery lengths, the KR808's have higher mah ratings and consistently they are stated as subjectively having noticeably longer battery life.

Thanks!

From what I know, yes, PWM. And no, not 5v native, they're regular 4.2. Not stacked. As to why they have better mah than Egos - dunno on that one.
