The custom Lipo battery with thermal effects and weight considered is really beautiful to see. I've been curious about custom Lipo battery shapes for rings because my fingers get cold when I wear rings. Would a battery heating up just a bit help make that comfortable for me?

Unless the ring is shaped as a heatsink/radiator, I imagine it would eventually get into equilibrium, and you wouldn't feel the heat-flux.
Is it possible that the "coldness" comes from its indirect affect on blood-circulation?

In something ring-sized? Maybe for about five minutes, and then the battery dies. (I assume you mean using resistive elements to create heat; heating the actual battery seems like a bad idea.)
