My underwater scooter with a 1kWh battery has a best practice of:

Good advice for most Lithium batteries.
The LiFePO4 chemistry is different in that it does not deteriorate on storage.
There's conflicting information on how to store them, I fear much of it is confusion with the other chemistries.

When I bought my LiFePO4 cells they had been untouched for several months since their production. They came fully charged, so I guess they can handle that.
When I did my first charge the chargers had them topped off in a minute.
So I think they would not deteriorate in their current 99% charged state.
Nor if stored at 40% for that matter, that's always a safe bet.

For confirmation go to people just like you.
For education go to people unlike yourself.
