Question on switching to LiFePO4 batteries.

I understand that storing them not fully charged is best. But I haven't found how much degradation it does to be stored in a fully charged state (but not connected to a charger). If it is a 10% degradation in life I I can live with it, but if it is a 50% degradation in life then I'd probably take the extra effort to discharge them for storage.

I haven't found anywhere on the internet where it quantifies the degradation in life due to starting out storage in a fully charged state.

I'll look at my literature for my cells and see if they say anything about how bad it is. like I said for short term I just keep it in my usage range as I run between 10% to 90% and never charge to 100% except the night before, or the day I am going camping I will go to a full charge and balance then reset my BMS to the regular operating range I use, but I am out almost every weekend (I work a 4 day on and 4 day off schedule) but when I am done with it for the winder I do drain it down to 50 to 70 which takes quite a bit. Usually, I just switch the fridge to 12V when I go to bed and then turn everything off the next day sometime. but I'll see if I can find anything that says how bad it is to leave them charged full.

so, the plot thickens everything I find says 50% or higher and if you're not using them for a long time recharge every 3 to 6 months. I think this is another area where older chemistry myths might be carrying over
