Good point. How about 3.7V? 80% discharged.

I am storing mine lower i left mine for a year at 3.85v per cell and did not notice hardly any voltage drop..... i figure 3.4 maybe 3.5v cell for a few months at a shot do a simple voltage check on them would be much safer tthis way.

and i would think storing a pack with more energy in it would make the packs life shorter anyhow.

Why store them at a lower voltage when the manufacturers store and ship them at 3.7 volts/cell?

because less voltage less energy no fires when stored I am thinking.

i bet you puncture a 5000 2S lipo stored at 3.85V per cell it will catch fire but i bet you do the same stored at 3.4V and no fire will happen.... that's what i am thinking.

I just think the lower storage charge helps preserve the battery.

I'd say it will catch fire either way. I'll stay with manufacturer's storage levels. It just plain makes sense.

Pretty sure I remember seeing published info somewhere that storing fully discharged degrades the pack at about the same rate as storing fully charged.

What you "think" is irrelevant. It's the hard physics and facts that are important.
