Completely agree - I don't see these being of much use except with very high ohm loads (or else perhaps on a very high mAh KGO). 99.9% sure you are correct that eGo batteries are "just" LiIon ICR batteries. Boosting those batteries, while certainly possible, is just inadvisable IMO.
I could see it being rather useful on a mod with replaceable (read: IMR) batteries though (like an external Kick). Wonder if the max amp limits that keep it "safe" with an eGo would hobble it in that use scenario though.
I was actually thinking more of using it on my telescope, but that is a very good point. I wonder if it would let it? I love the kick, but with the high humidity round here I had a bit of an issue keeping the contacts clean enough, for proper functioning.
