Storage is a state for Lipo chemistry.
It is the most appropriate voltage that reduces ionic exchange through the anode and cathode separations.
It is 3.8 to 3.85 v per cell.
You can get to this voltage by charging the pack ( if empty ) or discharging it ( if full ).
So the term "storage charge" is not appropriate if your pack is full!
Also note that when Lipo packs degrade, the internal resistance increases. I strongly recommend to note the internal resistance of a pack after the run-in period and keep a record of the value at the end of each season.
Once the internal resistance has doubled, discard the pack. No need to throw away your pack after 2 years in that case. Just on condition . These things are extremely nasty for the environment. Discarding on condition will be your little contribution to make the future of your children a little bit less messy...
