Ha, Nuttin to fear except for fear itself - lol!!...
The thing that’ll keep your LiFePo4’s happy is that once they’re fully charged to not let them linger on the charger for an extended period of time, and when not in use (e.g. in storage) store the batts at about 50% SOC (an approx equilibrium of about half the ions on the anode and half on the cathode thingy),
To avoid parasitical losses (when in storage) I added a disconnect switch directly atop the positive battery post (or pos cable per Victron)...I first checked switch with an ohm meter and it measured zero resistance when in operation...
