You need a BMS that monitors the 3 cells individually, to ensure balanced charging.

Also need to regulate the charge current to suit the cell/cells and a cut off circuit when the cell/cells reach their max. i.e. 4.2v/cell
Best/cheapest/safest is buy one that suits.

You would have to check what your maximum input voltage for your BMS is.
