    Can't speak to LIPO (other than to say it isn't a particularly safe chemistry), but for LiFePO4 there are lots of spec sheets in English from the manufacturers of the prismatic cells. I randomly grabbed one, and it says the storage temperature range is -20°C to 45°C, which is -4°F to 113°F. Ironically, the same sheet says the discharge range is from -30°C to 60°C (-22°F to 140°F).  I know that the cells create some heat when discharged, so to some degree they will keep themselves warm while cycling. I don't think I would trust it though.

    I've attached the particular spec sheet I pulled this from. I'll go see what others say. If there is more detail / explanation or significantly different ranges, I'll post back.

    EDIT: I found a spec sheet for a 302Ah cell from CATL (vs the 280Ah from EVE that I attached). It had the exact same temperature range for storage.
