Do they have a specified charge profile?
Yes they do but its not very well specified, in my case I plan on doing 2 stage.

These aren't the most terrific brand but cost was very low so no complaints.

Charging to the point just before the "knee" would occur on a bulk charger that craps out at too low of a voltage to get past the knee on any of the cells, then a slow dumb charger would trickle them after that point at a low enough current with a moderately low voltage limit as well so that no significant damage could occur if I managed to overcharge, more than likely though these aren't going to get fully charged most of the time anyway.
