i doubt if the lfp pack can do 16kamps trough a wire.
It does apply to a direct short between poles, but even the smallest cable length will drop this significantly.
I haven’t been able to test this yet, but i doubt if it will even reach 2k+ amps, unless you use really massive cables and very short lengths.
Also, terminal quality and proper torqing will make a huge difference.
Also, ratings generally are for the maximum voltage.
I have seen some vendors also specifying rates at lower voltages (eg 2000a @ 32V, 5000A@12V)
I personally think it will do for a regular 1 string bank.
Having multiple in parallel will require better fuses regarding its IR capability, but for a single battery string to 300-400Ah you might be good with a anl fuse.
If someone has the tools to do short current measuring that would be nice to see.
If someone has the equipment to do proper low resistance measuring (cable and terminal loss), and eg a storage oscilloscope to log the voltage drop during the full short (or a high current meter with sufficient fast response) I would love to see the outcome.
Maybe something
@Will Prowse can do?
It will answer the question is a high ir rated fuse lile like eg the classT or similar required, adviced or not nessecary in certain cases
