BMS without a balance option?
It protects against over-charge, over-discharge, and over-current. Another name for this function is Protection Circuit Module (PCM). According its specifications that module is suitable for 18650's. 

It should cut when any cell voltage goes too high or low, but it can't equalize the cell voltages. This isn't a problem if the cells are initially balanced and have very low self-discharge rates. 

However it might be worth providing a facility for manually checking and balancing the cells. On Lipos this is commonly done with a 'balance connector' which taps into the connections between the cells.
