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%?

LiFePO4 batteries like being charged up high, so you're probably fine keeping them plugged in.

You're right about not going under 20% often, but you'll want to charge to 100% at least periodically to allow the cells to balance.

Edit: Please make sure you're looking up information on Lithium Iron Phosphate batteries specifically, they behave differently from standard lithium batteries and a lot of the advice shared here won't apply.
