I work in a warehouse and i can't take in anything like phones or pretty much anything but my keys. I just leave my phone in my truck while I'm working at night. It's been cold and I was wondering if anyone has a way I could keep the mod warm while i left it outside. I thought about buying a thermos and putting it inside or buying a small piece of fleece and making a pocket to keep it in. Not sure if either of these would work but i would rather not mess up my SVD or battery. Pretty sure I already messed up my phone battery like this. Any suggestions would be appreciated.

AFAIK li-ion batteries are OK down to about 0*F. I actually think they're OK lower than that, but I'm not sure how much colder. You must not charge them when they're cold and they will not put out any power when cold, but it won't hurt them. I've been out with my camera numerous times in the winter in temps as cold as 5*F. I keep two batteries inside my coat and one in the camera. When the camera battery dies, I swap. When it's that cold I have to swap every 10 minutes or so. This has never, to my knowledge, shortened their life.

I'm not going as far as the prisoner thing. I'll leave it at that. And I don't know if the metal detectors would pick up on it. I work 10 hrs. At 5hrs I get a lunch break and I get off at 4am so its almost the coldest time of day. I was thinking thermos cause its air tight. I guess a Ziploc bag and hand warmers might work

I work in a similar situation on the night shift (midnight to 8 am) in a factory. No electronics are allowed. I bought a cheap insulated lunch box that has a small pocket in the top for a ice pack / warmer from walmart for $10. Then I bought a 100 pack of those hand warmers for about $40 and two of those plastic ice packs for $5. I put hand warmer / ice pack in the lunchbox's top pocket and place my mod in the bottom part before work. So far I haven't had to put a second warmer in and it's been below zero a handful of nights.

This might sound like a bit of overkill, but I just got a alarm for my car that can be programmed to start my my car on set intervals and its runs a while before shutting back off, you can do this on 1, 2, or 3 hours intervals, for 6 cycles.
It just happened to be a feature that I found out about after buying the alarm.
