1. The Hidden Hazard of Charging LiFePO4 Below Freezing
The chemistry of LiFePO4 batteries has a fatal flaw: if you attempt to charge them when ambient temperatures drop below 0°C (32°F), lithium ions undergo metallic plating on the anode surface, piercing the separator membrane and causing permanent micro-shorts, irreversible damage, or fire hazards.
2. The Litime Low-Temp Solution
Litime’s low-temperature protection line features integrated temperature sensors wired directly into the BMS. When temperatures drop below the safety threshold (typically below 0°C), the system automatically halts the charging current while still permitting discharge to run heating pads or loads. Once temperatures rise back up, charging automatically resumes safely, protecting your investment in harsh winter conditions.
