Been vaping for a year - using Boge cartos (the best) @ 6v and clear e2s @ 3.7v (finally got tired of all the work associated w/attys) - I'm using Riva batts and KR8s for the clearos and haven't purchased a volt meter yet and sometimes feel that I'm not getting 3.7 under load - especially with the Rivas - I could get the 17670 for my 6v mod but I'd like to have another mod for the lower ohm clearos that wld accommodate this battery and also give me the higher mAh rating and I believe more consistent power to the clearos - (not ready to spring for a VV yet, maybe next year) - If someone could chime in with the different mods out there that are designed for this battery I wld really appreciate it - Thanks
