Inverter and Battery unexpected shutown

Hi, I have a Victron Quattro 15kva and 2x BYDB-Box LVL 15.4kw batteries. Offgrid. The other day the system shut down with one battery BMS displaying error 105. The system will restart and then run for varying periods from minutes to a few hours. I imagine this is a faulty BMS unit, anyone had a similar issue? Thanks

for starters i would be looking up what a bydb 105 error means,

or charge both batteries untill 100% full and all cells are balanced. then see how it preforms

Further to this, I think fault E105 is 'volt sensor failure'? Not sure how to resolve this or why it occurs sporadically?
