Big Battery | ETHOS | 48V – 5.1kWh | UL1973 | Home Battery Backup LFP

Overview REVOLUTIONIZING RESIDENTIAL ENERGY STORAGE! Introducing the BigBattery 48V ETHOS system—an innovative, stackable, and scalable solution designed to power your home, solar setup, off-grid homestead, or commercial space. This 5.12kWh battery module is the foundation of the ETHOS system, built to expand up to 80kWh per control box by adding additional modules. Each module features Tier 1 LiFePO4 cells, the safest and most durable lithium chemistry available today. With 100Ah capacity per module, the ETHOS is designed for long-lasting performance, providing over 4,000–8,000 cycles at 80% Depth of Discharge (DOD). The system's advanced Battery Management System (BMS) continuously monitors voltage, current, and temperature, while passive cell balancing and an advanced battery control method optimize performance. For added peace of mind, each module is equipped with an integrated fire-extinguishing system. Designed for easy expansion, the ETHOS is a modular and stackable solution, id
