See that is the thing, I've spent all my money on 808 xl batts and I do not want to use an adapter (cause it will not preform as well), so I need something that is 808 thread.
Hi Larissa,
I've been using adapters to attach both eGo and KR808 clearos, tanks and cartos to my ProVari the past few weeks with no degradation that I can tell due to the use of adapters versus the 510 stuff I have (ProVari threads) or the 808 kits. Sure, the little adapters are hard to keep track of, but aside from that I'd say pick up a couple for $2-3 each and keep trying what's best for you, and you won't have to lose your investment.
...just make sure the adapters are going the "right way" -- I bought some for 808 Cartos to sit on 510 batteries first, but upon delivery realized what I needed were really what you're looking for - using 808 batteries with other "ends" - and needed to reorder.
Hope this helps
