Power Wall charging discharging usage?

This site may earn commission on affiliate links.
I have two Power-walls here in Northern California. I keep them 50% charged all the time for backup and use the other 50% to power my house during PG&E peak billing hours.

So during the day, at least in the summer they always charge to 100% and quickly, the I use 50% to power the house at night.

My question is do I ever need to fully discharge the two PW's to 0%.

What is the best practice charging, discharging practice for maintaining long life to the batteries?

I read somewhere that they need to be fully discharged but that would leave no back up in the event of an outage. We have a lot of power shut downs in the summer.

Comments, suggestions, appreciated, thank you
