Lowest safe storage temperature

[hyrulejedi86]

If I were to keep my Lipos in their sacks, which are then in an ammo case then placed in my 3 seasons room which will get below freezing in the winter (not usually below 0*F though)would this be ok? All would be at storage voltage.

Storing lipos below freezing (32F) is not recommended. No matter what charge you decide they should be held at( some say 40% others 60%). The crystalizing (freezing) of the electrolyte can lead to damage of the cells seperator construction and that will lead to premature cell failure. While storing lipos at cold temperature is actually a good thing, below freezing is a bad thing. Keep them above 0c or 32f for best performance. Heres is a brief commentary from a source. http://uterc.org/files/LipoStorageTips.pdf
