Should I turn off or disconnect my lifo4 in my caravan when not being used for several months
Yes. Disconnect it at 70-80% SOC
If you disconnect it close to full, your battery suffers stress.
If you disconnect it close to empty self discharge can make the battery go „kaputt“

unfortunately ppl have wildly different perceptions on what Soc means...
If I was to store my daily cyclers, I would charge them to the point that they go onto float... and then physically unbolt them from the system.
In my use scenario, I am looking for the greatest energy throughput, and NOT the longest battery life.
Hi,
Yes there are lot’s of theories but the most general advise for storing Lithium batteries, not being used for several months, had been given. :o)
Hi @Alan932,
you didn't tell us which type of lifepo4 battery you have. There are lithiums with built-in BMS and other systems use an external BMS. However, both my drain your battery over time.
So if I were you, I would switch the system off and make sure there are absolutely no current flowing in/out of the battery to prevent the battery/cells from getting completely dis- or overcharged. And if you don't have consumers that needs to be powered 24/7 while away, you gain nothing with the system running.
Make sure your lithium is charged to about 50% of its capacity when going into storage mode and every now and then check battery/cell voltage.
edit: and I see Markus commented also and recommends 70-80%, which is also ok. So don't be confused if these values don't match exactly ;-)
