From the manufacturer

Convenient, Scalable, Clean This convenient and stackable battery system from BigBattery includes two 5.12kWh battery modules and one control unit. A single set delivers up to 10.24kWh of renewable energy storage, and it’s possible to parallel multiple batteries for commercial installations. The stackable configuration provides a sleek aesthetic to any shop or garage, providing premium power without clutter. The BigBattery BMS monitoring software provides an easy way to remotely observe the battery system. The software shows real-time battery information including status, voltage, temperature, and cell data. Advanced Safety Features Internal Fire Suppression: While LiFePO4 batteries are some of the safest on the market, electrical equipment includes minor fire risks. To address this unlikely issue, BigBattery includes an internal fire arrestor system in each battery. Should the ETHOS’ internal temperature rise to an unsafe level, the fire extinguisher activates to prevent a fire from spreading to the rest of the energy system. Advanced BMS: The BMS (Battery Management System) continuously monitors the voltage, current, temperature, SOC (State of Charge %), and other aspects of the ETHOS battery. The control box displays this information, and if any of these parameters fall outside of safe limits, the BMS automatically shuts down the battery to prevent hazardous conditions. Included Components One order includes the following items. Systems requiring additional power can purchase additional batteries and an additional parallel kit for each battery. 2x stackable batteries 4x side covers Wall mounting brackets with fasteners 1x control box All needed power and communication cables 1x ETHOS base Impressive Discharge Capacity BigBattery designed the ETHOS to be discharged to 0% without damage. This keeps your battery functional regardless of the charging state. Since the BMS requires some power to function properly, BigBattery recommends 80% DOD (Depth of Discharge). This keeps the battery continuously functioning at peak capacity and increases the battery lifespan to 6,000 cycles. This feature, combined with a 12 year warranty and the BigBattery commitment to field serviceable products, makes the ETHOS a clear choice if you’re seeking a quality and long lasting battery. Weather Ready Since the ETHOS has an ingress protection rating of IP65, it’s suited for dusty installations or locations where it might get wet. UL Certified The ETHOS battery meets the standards for UL 9540A and UL 1973 certifications. To achieve these certifications, the ETHOS battery underwent rigorous testing to prove it could withstand high voltage or current without an electrical breakdown, could safely interact with the other parts of an electrical system, and could pass stringent fire safety tests.
