Default A Simple Question About LiFePO4 Batteries

No, pulling power from any battery is a chemical reaction. Most reactions work better the warmer they are (to a point).
When I do discharge testing on large UPS batteries, the assumption is 77*F, there are charts to offset the rate/runtime based on battery temp.
Low temps give less amperage and shorter run times.

Part of why an old car battery has issues when it gets cold.
