As long as the little BMS can dissipate the excess power the charge device is sending to the battery, you are OK. Most BMS 's cannot and will simply disconnect the battery when the voltage becomes dangerous, That won't be fun if you have to manually reset every day

MCU algorithm adjust voltage setpoint,
This is not Constant Voltage, not Constant Power.
Back to basic MPPT, this maximum power Point charging.
DIY person can do that with arduino, etc.
