Hi,
I think LI are wonderful. They are, unfortunately, not a good fit for me.
When the RV is in storage it gets down to -40, so no you can't help.
I have to laugh. Folks winterize their water systems all the time but can't winterize their batteries? It is called a battery disconnect switch. LiFePO4 batteries have very low self discharge. Charge it and then turn the disconnect switch. Done.
And no, I can't help you.
Perhaps I can help you. Li batteries best practise is to charge to 50% for long term storage. If one really wishes to push the envelope, discharge no lower than 40% and recharge to 85%. Every thirty days do a cycle to 100%.
The exception currently is to use Lithium Titinate. I can't afford $2000.00 per 100 amp-hours.
I hope the new solid state batteries will be usable in extreme cold.
