unless my batteries all got spent at the same time its got to be the cold weather. I live in north Florida but i have been flying in the 30s and 40s for the past week or 2 and I know my packs are hateing it.. I am going to make them little insulted booties to make them happy

I felt bad because I had no shoes until I met a man that had no feet

Lord yes.

Lipo voltage/current output falls dramatically below about 55-60D or so. As a rule, lipos work best at the temps at which people are comfortable. It seems silly, but it's the truth.

There are very few battery chemistries that like being cold.

I have an insulated bag, I put a couple of large water bottles with hottish water in the bag, then add LiPos at least an hour before flying. This will warm the LiPos so you can then plug and play.

On the 30C packs, I sometimes find the LiPos are cooler (actually almost cold) after flying than before!

I take them from the house and put them in an inner pocket of my jacket. Then, in the beginning of the flight, i hammmer on them pretty hard (sustained climbouts, tic-tocs, power moves) to warm them up even more and then fly like i normally do.

I have though about making a little insulator, but it mostly seems like keeping them warm pre-use is the key, as mine come down about lukewarm after flight so probably 80-90F

that's such a shame, and there was me thinking of taking the little TRex 450 out for a spin . .
