The DC busbar ships with spare positions ready for two more units. Need bigger steps? A higher-capacity floor-standing battery option (Dyness PowerBrick Pro, 14.3 kWh per unit) is available on request.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat about battery fires?\u003c\/strong\u003e These are LiFePO4 batteries — the calm, stable lithium chemistry — managed by a smart BMS, and every Powerbox G2 also has a built-in aerosol fire extinguisher that detects and acts in seconds.
