Storing Lipos cold?

[BrianG]

Storing them cold probably just reduces any chemical reaction (self-discharge, cell corrosion if at ~4.2v, etc). But to charge/discharge them, I agree with everyone else; get them warm. I store my packs in a metal drawer lined with cardboard. The metal is in case something happens and can handle a fire without melting. The cardboard is just an insulator in case there is an exposed wire I didn't catch.
