Quick question: how much current does a MC-E (or SSC P7) draw if connected to a fully charged (4.2V) 18650 LiIon? Enough to burn itself to hell even when well heatsunk, or manageable?
Thanks.

Depends on the voltage bin of the emitter. I'd imagine an MC-E would fry, even allowing for a bit of sag depending on the battery you select. I have a K bin MCE hooked up to my bench supply at the moment. Vf at 2.8 amps is 3.3V. You'd need to try and get a suitable voltage bin which I'm not sure you can do with the MC-E, but you can with a P7. I'll wind the input up to 4A tonight and measure the Vf
