The Bottom Line: A well-charged LiFePO4 battery in winter can survive storage in freezing temperatures with no extra attention. In other words, charge it, disconnect it, and forget it.
As winter approaches, proper storage of Lithium Iron Phosphate (LiFePO4) batteries becomes crucial for maintaining their performance and longevity. These batteries are known for their safety, efficiency, and long cycle life, but they still require specific care during colder months.
Extreme caution must be taken when charging LiFePO4 batteries while the batteries are below 32°F/0°C to avoid damaging the batteries. Some manufactures claim that their LiFePO4 batteries are easy to charge in freezing weather. Just charge them at very low rate. But most all battery experts recommend against it.
For example, LiFePO4 batteries (Lithium Iron Phosphate, the most common lithium RV battery chemistry) shouldn't be charged when the cells are below freezing (32F/0C), as that can seriously damage them.
