A BMS is not the device that decides the charging current.
Neither is the power supply.
It is the lithium charger that defines the charging current. The charger is the device that takes power from power supply and safely charges the lithium batteries.
The BMS, even if it has overcurrent and overvoltage protection, is only the last line of protection if the charger has failed to prevent further damage.
Do not connect a power supply directly to the BMS or batteries. The batteries or the power supply may be damaged, and damaged batteries are dangerous.
You need a charger which can charge the batteries with the current you want.
