I’m soon going to be putting into service a new 8 pack of LF304K cells, so trying to get up to speed with compression mounts. It’s not so easy with so many threads and posts about cell compression and differing opinions!
I have in fact already made a mount using M8 threaded rod and fixed end plates, no springs. If I have interpreted things correctly the procedure should be to get the cells discharged to a low state of charge (under 3V per cell?) then apply a 300kg force by tightening nuts on the m8 threaded rods and after that just lock the nuts with threadlock compound or locknuts and leave it alone?
Then the question is, how on earth do you know how to achieve 300kg with m8 nuts on threaded rod? Is there a rule of thumb for how many turns past finger tight, for example?
