Help!
Lipo storage and freezing temperatures.

I have no choice but to store my lipo packs outdoors, in an unheated shed. This is the first winter I've had to do this.
What effect, if any, does freezing temps have on Lipos?

Freezing temp of water? No issue.

If the Lipo electrolyte itself freezes it could cause damage, but AFAIK that does not happen until ~-30C and I doubt they will get that cold.

I have stored Lipos in a freezer where the temperature was quite constant over the time. They were wrapped in plastic food wrap to attempt to keep them dry. It worked well.

Storing outdoors, however, the temperature will not be constant. And even wrapping them to attempt to keep out moisture will not be effective.

If you are storing them outside because of a safety concern it would be better to keep them in a steel ammo box inside where the temperature won’t be freezing or fluctuating.

Why are you trying to keep them dry? They are not a lead acid battery. The only water that will hurt them is enough water to short them out.
