Lipo storage?

If you routinely do that, may want to consider putting the lipos in a ziploc bag and in the refrigerator - like the veg crisper and let them sit at 38-40F. You need to pull hem out ~24hrs before needing them to let them come back to room temp - leave them in ziploc so any condensation will be on outside of bag, not inside the lipos.
I've been away due to work and mine are sitting in a frig atm. The colder temps seems to suspend lipo aging process. Typically, 3yrs is about the age where lipo media begins to show signs of degrading.

Handling your lipo's well is indeed lengthening the life span but i am not sure about the refrigerator thing. It might seem that it works but there is no scientific explaination for that. Basically if you let a lipo sit at 20% it should be fine.
It'll age anyway.
BTW, nice that you can keep using it for 3 years. I never had mine that long thought. Also depends what you do with it. It makes a difference if you use a lipo in a simple car or a complex 3d helicopter.

Sitting at low voltage at room temp there is still a measurable self discharge long term. When you put them in frig at 38 - 40F, it is no longer measurable. Details have been on RC Groups. This is partly the reason bigger lipo companies use refrigerated storage.
I don't do this for week to week storage, but for anything that will be months or more. My life is pretty much on hold until years end - I'm working 2 full time jobs and a part time job (long story) so I have no time for anything, much less things rc. All my lipos are in frig - checked all voltages 3 months ago when my job(s) situation changed and they read the same now as they did then, I checked them 2 weeks ago.
Freezer is going to far, you don't want to get the media that cold.
