Is it better to let lithium batteries stay plugged in or constant 80/20 cycle (lemmy.world)

I am doing research on best practices for my lithium batteries and lifepo4 powerstation. There's some conflicting opinions and variation for cycle numbers.

Will leaving my things plugged in at 100% hurt it more than constantly unplugging at 80% and replugging at 20%?

Copied from a different comment of mine:

well, you see batteries should not sit at 100% at all and if so, only if you start discharging immediately. So just getting them discharged and charging them again to 100% where they will sit at for 20h a day won't help much against degrading the batteries.

"Choi 2002 shows that the constant voltage part is the most harmful to a battery, charging to 4.2V itself using constant current at 1C doesn't degrade it too badly, but by holding the battery at that voltage for an additional time causes most of the damage to the cell., [Source] (https://accubattery.zendesk.com/hc/en-us/articles/210224725-Charging-research-and-methodology)

I use a an App called Al Dente where I can set the maximum charge: https://github.com/davidwernhart/AlDente-Charge-Limiter

And there is also this: Basmati: https://github.com/aykevl/basmati

You can get it for windows too (googled that for you) https://www.thewindowsclub.com/battery-limiter-software-for-windows-10

For Linux my quick search found this: https://www.linuxuprising.com/2021/02/how-to-limit-battery-charging-set.html
