I used the figures that EVE supplied and keyed them straight into my active balancer. The active balancer shows SOH 100% and this is it's 5th year of operation.

The high voltage charge cut at 3.65v is good
recovery could be a little higher
High voltage alarm 3.5v, not point in having an alarm set higher the charge cut
High recovery reset to 3.45v
Low voltage alarm 3.0v
Low voltage alarm reset 3.1v
Low voltage cut 2.85v
Recover 3.0v
Low voltage forbidden charge 2.5v
Recharge restricted to under 1 amp until the cell voltage hold 3v with no load or charging, then full current charging can be applied
The reason for the higher low cell voltage cut is the drop off after 2.8v is very fast.
Even set for 2.7v, the cell will see close to 2v before the action takes affect if the discharge current is high.
If the discharge current is a trickle and the cell voltage is approaching the 2.7v mark, then a high current load is applied, there is a very real possibility of the cell being pulled below 0V resulting in a reverse current flow .... close enough to instantaneous death for an LFP cell, just getting below 1.5v results in internal material sacrifice in the attempt to maintain better than 2v ...... the result is always increased internal resistance and loss of capacity ....
LFP cells are more susceptible to low voltage damage than high voltage damage, but neither is good for long cycle life
