TechCella/Techex Self-Heating LiFePO4 Battery — Keep Power Flowing Even in Freezing Weather

When temperatures drop below freezing, most lithium batteries stop charging — but not TechCella/Techex.
The TechCella/Techex 12V 320Ah Self-Heating LiFePO4 Battery is built with an intelligent heating system that lets you charge safely and efficiently, even in winter.

❄️ Automatic Heating for Cold Protection

Our advanced Self-Heating Function activates automatically when the temperature reaches 0°C (32°F) or below.
At this point, the BMS prevents charging to avoid low-temperature damage and immediately starts heating.
Once the internal temperature rises to 3°C (37°F) or higher, the low-temperature protection disengages, allowing charging to resume safely.

When the battery warms above 15°C (59°F) or enters discharge mode, the heating automatically turns off — no manual control needed.
The heating film is powered directly by your charger (recommended ≥7A), ensuring smooth performance with no extra wiring or external heaters.

Temperature Accuracy: ±2°C

⚡ Designed for Winter Energy Systems

This self-heating design makes TechCella the perfect choice for:

• RVs and campers stored outdoors in cold regions

• Off-grid cabins and solar systems that need reliable winter charging

• Boats and trolling motors exposed to freezing environments

No more waiting for your battery to “warm up” — TechCella’s built-in heater takes care of it automatically, protecting your investment and keeping your power system running.

🔋 Safe, Smart, and Worry-Free

The 200A Smart BMS and EV-grade LiFePO4 cells work together to ensure consistent performance and long cycle life, while integrated temperature protection gives you confidence to operate year-round.
