That is, if the cell is rated for 1 A-hr, charge at 0.1 A for 16 hours. Peak cell voltage during this charge profile will be about 1.45 to 1.55 volts, which you can use to specify the minimum voltage compliance of the current source. You can try for a fast-charge profile, using a 1C or .5C charge rate, and monitoring temperature.

Appropriate charging current for parallel 18650 lithium cells
Typically, end of charge is determined by how much current flows into the battery. For a single 18650 cell, end of charge may be defined as the point where charge current drops to 25mA during the CV stage. But with 9 cells in parallel, it may never drop that low. Which brings me to the second point. Timeout.
Charging current/voltage for lipo batteries
But in a pinch (there''s no other option) I would consider slow charging an option, set the voltage to 4.2 V and limit the current to C/10. So for a 1000 Ah battery, charge with 100 mA up to 4.2 V. So on the supply: V = 4.2 V, Imax = 100 mA. That will slowly charge the cell and charging will become slower when the cell reaches its full charge.
