On my Chroma batteries also 3S, I make an effort to land with the controller showing 11.1v or so. The battery rebounds a bit when you take the load off.
I generally target 3.75v to 3.8v per cell so I don't need to be dead precise to store.
I like to do it that way because the manual discharge methods I have are slow. Also I feel it's better on the battery not to discharge it as deeply as I could. Before I put them up I check the cell voltages, if one cell is only .01 off I'll go ahead and put it away. If not I'll put it on a balancer.
I also store mine in the fire retardant cases individually in the top shelf of the fridge. It's not as cold there but it keeps them at a stable cold temp. They get put in a ziploc bag as well to prevent condensation when I set them out to normalize to air temp before use.
My batteries are probably well over 3 years old and still perform well.
