flippy said:the BMS is a PROTECTION, not a regulator. you need a power supply (aka: charger) that has the proper voltage ceiling, that's it.
No; an 18650 would be massively overcharged by a 48v charger, unless it has a BMS on it with protection against that that can handle that much voltage (a single-cell BMS's FET may not rated that high).inline_6ix said:Will a 48v charger charge an 18650 to its nominal voltage or 4.2?

But it will charge a series set of them to their full voltage; assuming the 48v charger is for a 13s pack, and you have 13 cells in series, and the charger is set for 54.6v (or higher if it has a pack-level BMS with cell-level overvoltage protection).
Also, the "nominal" voltage of common Li-Ion 18650s is 3.6 to 3.7v. The "full" voltage of those cells is 4.1 to 4.2v.
