Hy!
I have just updated my Multis to Firmware version 494 2 days ago and now Multies when charging Victron Smart battery reaches Absorption it raises voltage to 64V !!!
Absorption voltage set in Multies is 56,8 V. BMS disconnects and temperature of batteries is high (over 35 C).
My 3 paralell Multies (MultiPlus 48/5000/70-100), in ESS in "Optimized with BatterySafe" mode, 2 serial 24V Victron Smart LiFePO4 batteries protected by VE.Bus BMS.
