EG4 LL-S V2 Lithium Battery 24V 200AH UL 1973, UL 9540A

The EG4 LL‑S V2 24V 200Ah Lithium Battery is a server-rack style LiFePO4 (lithium iron phosphate) energy storage battery designed for off-grid, hybrid, and backup power systems. With a nominal voltage of 25.6V and 200Ah capacity, it delivers approximately 5.12kWh of usable energy, making it ideal for residential solar storage, cabins, RVs, and small commercial setups. Built using Tier 1 LiFePO4 cells, the battery is engineered for long-term reliability, offering up to ~7,000 deep cycles and an expected lifespan of 10–20 years under normal operating conditions. The LL-S V2 includes an advanced internal Battery Management System (BMS) that provides protection against overcharge, over-discharge, short circuit, and temperature extremes, while also enabling closed-loop communication with compatible inverters for optimized performance. A key feature is its UL 1973 and UL 9540A certifications, ensuring compliance with safety and fire standards required for residential and code-compliant installations—especially important for indoor or attached garage installs. Designed for scalability, the battery supports parallel expansion, allowing users to build larger storage banks over time. It also features a front-facing LCD screen for real-time monitoring of voltage, state of charge (SOC), and system status.
