EG4 Wall Mount Indoor Lithium Battery 280AH | 51.2V | Indoor | Heated UL1973, UL9540A

EG4 Wall Mount 280AH 51.2V Indoor Lithium Battery

The WallMount Indoor 280Ah batteries are designed for indoor energy storage applications in low-voltage residential settings. These batteries utilize lithium iron phosphate cells renowned for their top-notch safety features, supported by an intelligent Battery Management System (BMS). The BMS monitors and logs real-time data on each cell's voltage, as well as the current, voltage, and temperature of the module. Additionally, it includes a passive balancing function and advanced battery control techniques, enhancing overall battery pack performance.
