Operating Instructions
The LOSSIGY LiFePO4 battery is equipped with a 200A Battery Management System (BMS) that provides multiple layers of protection and allows for Bluetooth monitoring.
Bluetooth Monitoring
Download the LOSSIGY Bluetooth app on your smartphone to monitor real-time battery status, including voltage, current, temperature, and remaining capacity. This feature allows for convenient oversight of your battery's performance.
BMS Protection Features
- Overcharge Protection: Prevents damage from excessive charging voltage.
- Overcurrent Protection: Safeguards against currents exceeding safe limits.
- Overdischarge Protection: Prevents deep discharge that can harm battery life.
- Low Voltage Cut-off Protection: Automatically disconnects the battery when voltage drops below a safe threshold.
- High Temperature Cut-off Protection: Shuts down the battery if internal temperature exceeds safe operating limits.
- Short Circuit Protection: Protects against damage from short circuits.
