Fully charged lipos go flat fast in very cold ambients. Try to keep the lipos warm just until you go outside to run. That will give you a head start and gain some more run time. But after about 5-10 min freezing temps will set in and the lipo goes flat fast. Once they warm up they are normal again. This is normal for most any kind of batteries. They have operating temp limits. When Crawling yesterday in the snow storm, one of them hit LVC early. When I got home and the pack warmed up, it had 3.89V per cell and was pretty balanced at that. (2S, 52000mah gens-ace-r-spam) I believe Exocaged RC (not 100% sure it was he) did a test on Fully charged lipo temps from 120F (heated in an oven) to freezer temps. The lipos actually performed best super hot over 120F. That's why Racers discharge very low and charge at very high rates. To get them very warm for a race. The punch and amp delivery is high.Didn’t you have voltage cut? Did your lipos worked well? My experience on snow was frustrating, could bash only 5 min than went in voltage cut?maybe my lipos on snow are poopy?
