Ah, I should take down that old post...Or at least edit it so it's more accurate.
V1.0: Has been discontinued for several reason:
-No Protected 6v Option
-Forced the consumer to spend $$$ on pricey tops to get additional atomizer models (I.E. ability to use 510, 801, 901 would've cost $59/pc)
-1600mAh
batteries, which have a good battery life, but we wanted more
Here's why added The V1.1 (the only ones you'll be able to get now):
-Only one top, it comes default with the 510. We made this choice as 85% of all silverbullets from the first run were sold with the 510.
-Made adapters affordable for the consumer
-Longer battery life, 2400mAh, that's 33% increased battery life over the first one.
As far as 18500 vs 18650:
V1.0 (which are no longer available) used the 18500.
V1.1 (Which are on Preorder right now) use 18650.
Sadly the 18500 will not fit into the newer tubes. But since the initial goal of the SilverBullet was to have a long battery life, with a good solid body...that fits comfortably in ones hand...we felt this change was necessary
Hope that answered your question
