Thanks, Mooch. I didn't realize there are now so many choices for 20700s. But I'm still going to stick to my Sanyo 20700B cells. I vape 20-25 watts in a dual battery mod, so even though they are just 15 amp batteries, I don't even use close to that. And I love the 4250 mah, more than any of the cells you mentioned. If I had to stick to 3000 mah cells, I might as well vape HG2s and not bother with 20700s.
