Greetings Mbonnani,
First and foremost, please be aware of the inherent risk of running a mod <1.0Ω and I highly recommend a look into
this thread and the microcoil thread for great insight and tips/tricks.
As far as the batteries...
AW IMR 18650 1600mAh (Red/15C) are the business, the red 2000mAh also work great (10C). I would not recommend subohm vaping if you're going for smaller batteries.
AW IMR 18350 700mAh (Red) have a 6A limit which on SLR terms would kill it if you dropped below 0.7Ω on a freshly charged battery, not to mention the battery would be drained of life fairly quickly.
I'm not aware of higher C rating for any other 18350's.
If you're planning to run subohm I suggest sticking with larger batteries (18500/18650's) or know that your battery has the C rating required. Lastly, invest in a DMM ($20 at Home Depot), they are sufficient for reading coils.
Otherwise welcome and happy vaping!
P.S. As far as NOALOX, you only need to put small amounts on the battery contacts (clean them first), oh and any light oil based lubricant works fine on the body threading/lock ring. I can almost spin the entire bottom half of my K100 off with a good flick after rubbing the inside down with 5w-30 synth
