This setup won't draw enough to notice, it's minute, by comparison, not even one percent. These batteries have current to spare, they are made to be shorted out. So you also never need protection circuitry, or any of that. They have to be charged like other lithium batteries, but that's where it ends. If I had to put in a regulator without soldering anything, I'd get a 3 wire servo connector, a small one, and just plug the thing into the end. Then you can do the whole thing just by splicing wires. Use an LM78L05 5v regulator if you want more power. If you use a plug you could try both. I love regulators, I have a coffee can full of them. Transistors can be handy, too.
