That's a light oil setup... is the track a loose surface?

As far as cold lipos go it's known that they don't like cold. Some of the older generation cells are completely worthless if they are around freezing temp. Even at "room temp" they don't perform as well as when they get warmed up a little, more like 90 or 100 degrees. THey work better the hotter they get. Nimh are the same... run them when they are a toasty 120-140 degrees for best performance. They do feel flat when cold (both types).

So in the heat of summer it's not an issue, but when it's in the 40's or 50's outside, some lipos will only crank out about half their power... the airplane guys keep them warm and even put a "blanket" around them in the plane in the winter.

Not all lipos are as sensitive to temperature, and I don't know how much effect if had on my cars that day I had trouble. In the future I will warm the packs before running.
