LifePO4 lithium batteries - storage

Any particular rules on charging, recharging, storage times? The charger that came with it doesn't have a charge meter, just a green light for charged and red light for charging. I assume you can top off to green light for storage, or is that bad?

The chargers and batteries have built in battery management systems so they are pretty much plug and play.
You are more likely to have a failure from a defect or bad part than your charging schedule with lifep04 batteries

I don't want to leave it plugged in 24/7 either, I'd like to plug it until it's green then put it away. I know that's bad for lead acid, better to keep it trickled. But this lithium stuff can I charge and put away? And for how long? I can go months in between usage. In the case of the one I'm charging now, I haven't used it in a year.

Thats what I do with mine. Only takes an hour or two on the charger to get back to full and they are ready to go for next time. I havent noticed any drop in charge level when stored without a trickle on

LFP batteries should be fine if stored close to 100% charge unlike NMC(like new power tools) which should be left around 80. May not be ideal but not nearly as bad as doing that with your standard NMC lithium ion cells or packs.
Charging is CCCV meaning it’ll charge max current to like 85-90% then regulate voltage. It should be automatic but you don’t want to use a lead acid or NMC charger to charge LFP cells.
