Extra Battery for ECOFLOW DELTA Pro 3600Wh
The smart EcoFlow DELTA Pro extra battery allows you to double or triple the autonomy of an EcoFlow DELTA Pro station.
Each additional battery adds 3,600 Wh of capacity. It is ideal for long-duration events, off-grid installations, construction sites, food trucks, or equipment that needs to operate for several hours without the ability to recharge.
Important
This battery does not work alone. It does not have electrical sockets to directly power your devices.
It must be connected to a compatible EcoFlow DELTA Pro station using the designated connection cable.
Available Capacities
- DELTA Pro alone: 3,600 Wh
- DELTA Pro with one additional battery: 7,200 Wh
- DELTA Pro with two additional batteries: 10,800 Wh
One DELTA Pro station can accommodate up to two additional smart batteries.

What Autonomy Gain?
An additional battery approximately doubles the autonomy of the DELTA Pro.
Examples with a DELTA Pro and one additional battery, making a total of 7,200 Wh:
- 100 W device: approximately 61 hours
- 500 W device: approximately 12 h 15
- 1,000 W device: approximately 6 hours
- 2,000 W device: approximately 3 hours
- 3,600 W device: approximately 1 h 40
These durations are approximate. They can vary depending on the device, its operating cycle, temperature, and conversion losses.
For What Needs?
The additional battery is particularly recommended when:
- the installation needs to run all day or all night;
- no charging point is available on-site;
- multiple devices need to be powered simultaneously;
- a refrigerator, cooler, or sensitive equipment must remain powered;
- the energy requirement exceeds the 3,600 Wh of the DELTA Pro alone;
- a safety margin is needed for an event or professional activity.
Check Before Your Use
The additional battery only increases the system’s autonomy. It does not increase the output power of the DELTA Pro, which remains limited to 3,600 W during normal operation.
Due to its weight of approximately 38 kg, it must be transported and handled with care.
Communicate the power and duration of use of your equipment: we will determine if you need a DELTA Pro alone, an additional battery, or two additional batteries.
