Just out of curiosity, I just search google for "how many cells in 18v li ion battery", and up come quite a few hits showing people opening up such batteries. Many had either 5 or 10 18650 cells. Every one I looked at did have a battery management system (BMS) PCB inside it.

I guess that doesn't change the view that you can use a general purpose PSU for charging, as I think the BMS is mainly there to equalise cell charging?
