4. Safety Information
The Elefast 48V 105AH LiFePO4 Battery features a built-in 200A intelligent Battery Management System (BMS) that provides multi-protection functions to ensure safe operation and longevity:
- Overcharging Protection: Prevents the battery from being charged beyond its safe voltage limit.
- Overdischarging Protection: Stops discharge when the battery voltage drops too low, protecting cell integrity.
- Overloading Protection: Manages current draw to prevent damage from excessive loads.
- High Temperature Protection: Disconnects the battery if internal temperatures exceed safe limits.
- Short Circuit Protection: Automatically cuts off power in case of a short circuit.
- Low Temperature Protection: The BMS will immediately cut off charging if the battery temperature falls below -4°F (-20°C) or below 32°F (0°C) for charging, and will resume automatically when the temperature rises to 0°F (-17.8°C).
