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%?
None of the information you find here or on the internet in general will be correct, because most of information is either older nicad or nickle metal hydride, or when talking about lithiums people are talking LiPoly which is not your Lithium Iron Phosphate.
Your best bet is to ask the LiFeP04 manufacturer
