The latest EcoFlow DELTA Pro Extra Battery price in Pakistan is Rs. 399,999/- updated on October 21, 2026.

The EcoFlow DELTA Pro Extra Battery is an expansion battery for the EcoFlow DELTA Pro portable power station. It is not a standalone power station. Instead, it connects directly to a DELTA Pro to double or triple its capacity, so appliances and equipment run longer.

Expandable Capacity

A single extra battery adds 3600Wh of capacity to a DELTA Pro. This doubles the total capacity to 7.2kWh. If you connect a second extra battery, total capacity rises to 10.8kWh.

Charging and Discharging

When you connect it to a DELTA Pro unit, the extra battery charges and discharges in unison with the main unit. It also takes advantage of the DELTA Pro’s fast-charging methods. These include AC outlets, solar panels, EV charging stations and the Smart Generator.

With an EcoFlow Smart Generator, you can also charge the extra battery independently of the DELTA Pro.

Smart Control and Display

Once linked to the main unit, you can monitor and control the extra battery in the EcoFlow app. In addition, a built-in LCD screen shows information such as remaining charge, input and output.

Durable LFP Chemistry

The battery uses Lithium Iron Phosphate (LFP) chemistry for a long lifespan. According to EcoFlow, it lasts up to 3,500 cycles to 80% capacity and 6,500 cycles to 50% capacity.

Who It Suits

The EcoFlow DELTA Pro Extra Battery suits DELTA Pro owners who need longer backup during long outages. For example, it helps homes, clinics, offices and off-grid cabins keep essential loads running overnight. Because it charges with the main unit, you manage both as one system.
