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%?

    I’m not sure if the general advice for lithium ion batteries will apply to lithium iron phosphate batteries.

    For lithium ion batteries, I like to charge them during the day rather than leaving them plugged through the night, but that’s because I don’t know if I can trust the BMS (my father would keep his phones plugged whenever he was home and every single smartphone he owned eventually had inflated battery syndrome, even though I warned him many times, I don’t know if he still does that or not, but his current phone shows no sign of inflating yet).

    My previous phone was a Sony phone, and their smart battery management tool allowed the phone to charge to 80% (or 90%, I don’t quite remember), stop, and only start charging so it would be full by the time I usually wake up, which I thought was rather smart. I often charge to 90% rather than to 100% when I know I won’t need the full 100%, but if I know I might not have an opportunity to charge or going to need to spend a lot of battery on something, I’ll charge it fully.

    I don’t know much about lithium iron phosphate batteries other than that they typically have longer lifespans and better fire safety compared to lithium ion batteries, but it doesn’t mean they should be abused beyond the specs recommended. Are you doing a solar & battery installation? If you’re DIYing it, make sure to do a lot of research about getting a good BMS and installing everything correctly so you don’t burn your house down by accident.

      Thank you for the reply. Yes I am off griding running off solar just got a bluetti eb3a to manage panel power since I’ve never done any solar before and didn’t want to mess things up. it seems pretty smart.

        I just googled it, it seems like it is an all in one system. I assumed you were talking about buying battery cells and designing your own system, but since you have a self contained system (which already obviously has a BMS), you can ignore the last paragraph I wrote previously.

        Hope it serves you well.

        This would have been useful to mention in the original post.

        just got a bluetti eb3a to manage panel power since

        We have very little control over what the solar does with “power stations”. I’d just leave the panels plugged in.

        I’ve never done any solar before
