51.2V (48V Class) 170Ah Mobile Indoor & Balcony Sodium-ion Storage Battery, 8.7 kWh

This 51.2V (48V class) 170Ah sodium-ion battery is purpose-built as an indoor living-space mobile storage battery and European Balkonkraftwerk storage solution. Equipped with four heavy-duty silent casters for smooth mobility, integrated top breaker protection, and proprietary smart BMS, it provides dependable plug-and-play power for modern households.

Thanks to breakthrough sodium electrochemical kinetics, the battery maintains stable 85%+ discharge capacity even in extreme sub-zero winter temperatures down to −40 °C without requiring internal heating pads. It supports standalone living-room deployment or series connection for higher-voltage configurations.
