Many battery users are unaware that consumer-grade lithium-ion batteries cannot be charged below 0°C (32°F). Although the pack appears to be charging normally, plating of metallic lithium occurs on the anode during a sub-freezing charge that leads to a permanent degradation in performance and safety.
You are more aware of battery chemistry than I, so hopefully you can answer this question. I am aware if the cod charging issue, but can you store or discharge LiFePO4 batteries below freezing ? How far below ?
It may be different for other manufacturers, but my Battleborn batteries can be discharged down to -4°F. They can be stored well below freezing, preferable at 80% SOC, and they suggest not traveling with them below -15°F because the internal supports may fracture due to the cold & vibrations.
