At the current draws that the XR-E and the XP-G's will be sucking down, Solder will be sufficient. obviously, don't put the blob of solder on the batteries, put it on the C8 instead. (you may need some extra flux for it to wet to the surface though)
soldering the 18650's is very bad for them, they don't like heat.
some people put little magnets on the front of their flat-top 18650's instead of more permanent modifications btw
