We had an accident in our Fifth Wheel travel trailer and it is going to be at an RV repair facility for 2 weeks to a number of months based solely on parts availability. During it’s stay at the facility it will not be connected to any sort of shore power except brief periods when they need it for repairs and/or testing.
We have 2 DIY LiFePo4 12v batteries using 4 Lishen 272ah cells per battery.
Since they will not be connected to any sort of charger at all, I’m planning to disconnect the BMS but want advice on what voltage would be best for storing them for several months if necessary.
Note, the cells are brand new and only put in service 2 days ago which turned out to be great timing given we were stuck on the shoulder of a freeway in Southern California for 29 hours before we could transport it to the repair facility ?
Also, I’ve read through the following threads but they both had their batteries on chargers and were looking for long term charging profiles:
Thanks for any input, especially if @Will Prowse can give some advice.

Storage of LIFEPO batteries in my RV
I made a 560ah 12v battery and installed it in my RV. I am not going to remove it for storage so I figured out you can create custom charge profiles in my Victron SCC... I labeled one for "storage" and set to 13.33v (about 35%-40% so about 200ah) which should help my shelf life especially in...

Long Term Storage Charge Profile
I realize that I could just discharge my LiFePo4 battery to 40-50% prior to storage, and I would probably be just fine for at least 6 months during winter storage. However, for my purposes (a boat stored away from where I live), It would reduce my workload significantly to be able to just set...
