I've been using LR cartos (Boge 2.0 ohm from SmokTek) on my GoGo batteries with an 808 adapter. Both my GoGo batteries died within a week or two of each other. Coincidence? I knew that the lower the resistance of the carto, the quicker the battery would drain, but since I was getting 2-1/2 days per charge on my GoGo batts, that wasn't an issue. I didn't suspect the cartos would kill the batteries, though!
I just ordered the Igo Crystal Vision kit with some regular Igo cartos to go with it. I'm not sure I even want to use the LR cartos on the Igo when I get it. I guess I'll use them up on older batteries I don't care about until the LR cartos are gone. From what I've read, the Igo with the Igo cartos is a pretty good setup. I'll just need to get some standard resistance, regular-sized cartos to use on it when I'm out, so I can keep it in my pocket. I'm sure the Igo with the Igo cartos on it will be too long.
Does anyone who knows more about this stuff than I do know if my suspicion about the LR cartos killing batteries is likely? I think I remember reading someone somewhere say that they only use LR cartos on batteries they don't care about. But I also think I remember that person, or someone else, saying that the issue is with resistance lower than 2 ohms. I've read so much by so many people in so many threads that I can't remember where I saw what!
