Smart BMS 12/200 High system+ Voltage

Hi guys, I have just noticed my smart bms 12/200 system + gets to 16v which is also linked to quattro. Battery voltage is not affected. Just do not fully understand this unit.

Hi, I have the same problem, it goes from 14 to 16,3 V. Does it make your multiplus restart too?
Did you find a solution?
Thank you,
Samuel
