Lithium batteries dont like being stored fully charged they will degrade over time.

This is a solved problem. Most EVs won't let you charge it to the actual 100% level or discharge it to 0.

[–] [email protected] 2 points 10 months ago

Exactly. Really, "fully charged" should just be conceptualised as being at a sensible safe point, with the acknowledgement that it's possible to "overcharge" the batteries to an even higher level, chemically speaking, but that all sensible devices don't let you do this.

So only charge it to 80% and pretend 80% is 100%, like iPhones do. Why is that a concern?

[–] [email protected] 1 points 10 months ago

Or you could just use all of the space for a sodium battery and fully charge it as it won't need long term storage in that state.

You're right. Forgot about that. Shoot.
