Note that most of the bms's are not shutting down to low pack voltage but most likely to low cell voltage. The drop in manufacturers wouldn't want the packs eatting their own cells.
That is why it's best if possible to have a user adjustable inverter for low shutoff than have the battery use it last hail mary shutdown event.
The Victron monitor has something going about that as one of its features for how to install it, except it is for whole batteries in series too:
"More about midpoint voltage:
One bad cell or one bad battery can destroy a large, expensive battery bank. When batteries are connected in
series, a timely warning can be generated by measuring the midpoint voltage. Please see the BMV manual,
section 5.2, for more information.
We recommend our Battery Balancer (BMS012201000) to maximize service life of series-connected batteries"
