Okay, let's cut to the chase on this one.  There are lots of companies making/selling lithium ion batteries (LIBs) these days.  And they all have there marketing spiels to get you to buy their brand of LIBs.  Who ya gonna believe?  Well, here is a link to a very technical treatise on LIBs, how they work, and what temperature extremes do to them.  I'll give you a hint - cold does affect LIBs.  Here's the link:

Temperature effect and thermal impact in lithium-ion batteries: A review

Hey Bob -- I hope you read that whole article....just some of it was giving me my very own Redox Reaction....so I had to carefully back out...

Yeah, it was just a tad on the technical side for sure.  But, hopefully, you and others will have gotten deep enough into it to understand that cold temps do have an impact on LIB battery function.  Actually, on ANY type of battery in common use today.  But the nice thing about LIBs is that you get full voltage until the instant you don't where lead acid batteries degrade slowly over time.  I monitor my lead acid battery level at the end of each ice session and I don't recharge until it gets down to about 11.8 vdc.  The unit functions just fine up to that point.  And my batteries last at least 5 seasons or more.  I don't see any real need for the more expensive LIBs as I haul my gear with a power sled and don't worry about weight.
