Winter 640 ah Lithium batteries shut down sequence

[Against The Wind]

Hello friends. We’re putting Olly up for a while and are looking for the proper shut down sequence for our batteries. The way we see it now is shut off shore power, shut off solar (red switch in cabinet street side), wait until batteries achieve 50-80% SOC, shut off inverter(red switch street side sub access compartment), shut off batteries (blue lighted button switches on batteries). Does this sound like the correct sequence of events or no? When we restart in the Spring, just reverse order. As always, your response is most appreciated. 😊 Thanks

Yes, if your 2024 still has the 30 amp breaker under the street side bed next to the actual inverter. The newer Oliver no longer have that 30 amp breaker. Oliver went to a large fuse.

Thanks so much, John. One more question, our trailer has the Optifuse resettable breaker located by the xantrax main shut off? Picture included.  Is this the circuit breaker & does it need to be turned off? Thanks again for all your help.

Attached is Lithionics' most recent (to my knowledge) battery storage protocol.  Note that if your batteries are "subject to winter conditions", Lithionics recommends that you either leave them connected to shore power (so the internal heaters can protect them), or remove them and store them "above freezing".

Leaving shore power connected avoids the need for shutdown.  For what it's worth, during our very cold winters in central Idaho, we leave our Elite II connected to shore power, but do a charge-discharge cycle after 6 months of storage.

Your picture shows a on-off switch, not the Optfuse. Best to check with OTT (to be sure) regrading the switch you show in your picture. Or you could trace the wiress to determine their use.
