So I've made my decision, sorta. I placed an order for 20 packs of boge lr510 cartos and two 1000mah "ego" batts from GH1. The 1000mah batts are only $13 a piece so I won't really care if they are harmed by the LR cartos. That way I can keep my joye batts separate from all that LR buisness. This will give me time to either make a decision on a mod or just make my own. Thinking about it, all an 18650 device is, is a way of connecting an 18650 batt to an atty/carto. Granted If I make one it won't be even close to as ergonomic or asthetically pleasing as a production mod. Thanks again for all your input everyone.
