How cold is too cold for lipo?

[RUSTY XL-5]

About this time of the year, I go on a lot of camping trips, and even some during the winter up in the northern states. Naturally, I want to take my R/C's along.

I was wondering what temp is too cold for a lipo before the batt becomes harmed? Also, do lipos have a specific temp at which they perform the best?


Thanks!
