Add a second for 10,800Wh: enough for 24+ hours of whole-home essential backup including refrigerators, medical devices, HVAC fans, lighting, and communications.\u003c\/p\u003e\n\u003cp\u003eEach extra battery connects to the DELTA Pro's expansion port and charges simultaneously via any input source — solar, AC, car, or smart generator. With 1600W solar input, the full 7200Wh system recharges in approximately 4.5 hours from EcoFlow 400W panels, while AC wall charging fills the combined system in under 3 hours. The BMS manages charge balancing between the main unit and batteries automatically, with no user configuration required.\u003c\/p\u003e","brand":"Ecoflow","offers":[{"title":"Default Title","offer_id":51465238577430,"sku":"DELTAProEB-US","price":1099.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/9724\/5974\/files\/ecoflow-ecoflow-delta-pro-smart-extra-battery-28492995952713_1024x1024_2x_1e54bd9c-55b6-485f-89a5-2298aee1b1cd.jpg?v=1782268361","url":"https:\/\/energywarehouse.store\/products\/ecoflow-delta-pro-smart-extra-battery","provider":"energywarehouse","version":"1.0","type":"link"}
