cold is only good for battery storage. cold shortens runtime. however not that short!
ask geomangear about your issue - the company is very responsive with information
I wrap mine in bubble wrap and shove the wholem thing in a water bottle, then cover it with plastic bags and rubber bands. it's water proff and provides some thermal protection, but really riding below freezing - that wrap doesn't keep it any warmer, not after 15 - 30 minutes, you know? anyway, mine lasts much longer on green in even lower temps.
