EG4 LifePower 4 V2 Lithium Battery 48V 100AH UL 1973, UL 9540A

EG4 LifePower 4 V2 Lithium Battery 48V 100AH (UL 1973, UL 9540A)

The EG4 LifePower4 V2 Lithium Battery 48V 100Ah is a rack-mount lithium-iron-phosphate (LiFePO₄) energy storage battery designed for residential, off-grid, and hybrid solar power systems. With a nominal voltage of 51.2 V and 100 Ah capacity, it provides 5.12 kWh of usable energy, making it ideal for scalable home energy storage and backup power applications.

The battery features an integrated 100 A Battery Management System (BMS) that protects against over-charge, over-discharge, over-current, and temperature issues while ensuring reliable operation and long service life. It uses 16 UL-recognized prismatic LiFePO₄ cells and is tested for 6,000+ deep cycles at 80% depth of discharge, providing dependable long-term performance.

Designed for modular energy storage, the LifePower4 V2 supports parallel expansion of up to 64 batteries, allowing systems to scale to over 327 kWh of total storage capacity. The battery also includes CAN bus and RS-485 communication ports for closed-loop communication with compatible inverters, simplifying integration into modern solar systems.

Safety features include UL 1973 certification and UL 9540A fire safety testing, along with built-in protections such as an emergency stop (E-Stop) function and dual onboard fire arrestors. These features make it suitable for residential installations where safety and reliability are critical.
