The mistake that many people make when using LiFe batteries ( of any brand ) is that they don't wire them with the ability to re-set the BMS or diagnose them.
My suggestion for wiring all brands of Li batteries in a 12 volt system is:
( neg bus bar ) -- ( battery A ) ---- ( breaker ) ----- ( positive bus bar )
( neg bus bar ) -- ( battery B ) -----( breaker ) ----- ( positive bus bar )
( neg bus bar ) ---( battery C ) ---- ( breaker ) ----- ( positive bus bar )
( neg bus bar #2 ) ---( significant load 1 ) ---( breaker ) ----- ( positive bus bar )
( neg bus bar #2 ) --- ( fuse block ) -----( breaker ) - ( positive bus bar )
etc
This avoids the risk of putting too much power through a battery terminal and over heating it, as each battery is designed for max 100 amps continuous, not an unlimited amount of amps going through the terminals.
it also allows re-setting each internal BMS simply by turning the breaker off and then back on - very simple and effective.
Last but not least, it also makes it much safer to do routine checks, edits and maintenance.

There is a reasonable chance that the battery that is mis behaving was wired so that 3 - 400 amps were going through the terminals instead of the 100 amp spec of the battery.
