Product Details
The EcoFlow Delta Pro Smart Extra Battery connects with a Delta Pro to double total capacity to 7200Wh. Connect two to the Delta Pro for a staggering 10.8kWh to use off-grid.

Powerful, Lightweight Energy Expansion:
Designed specifically for use with the Delta Pro Power Station for Doubling your Storage Capacity!
Requires no gas and emits no pollution.
Informative LED Screen displays watt input/output and remaining run time.
The Delta Pro’s Smart Extra Battery benefits from all the charging methods the Delta Pro has, including 6500W Multi-Charge!
Massive Expansion Capabilities:
Double or triple the capacity of your DELTA Pro to 7.2kWh or 10.8kWh. That will give you days of power for your essential appliances!
EcoFlow’s battery management system provides real-time analysis and regulation of voltage, current, and temperature. This unique protection mechanism makes the Delta Pro Expansion Battery an incredibly safe and efficient home battery.


Flow Charge & Multi-Charge Technology:
The Delta Pro’s Smart Extra Battery benefits from all the charging methods the Delta Pro has, including 6500W MultiCharge. That means you can charge anytime, anywhere as long as your extra battery is connected to the Delta Pro. Once connected, they’ll charge/discharge in unison, keeping the battery percent level across both units.
EcoFlow’s Flow Charge charging technology isn't just fast, it's safe too. The battery management system ensures safety and longevity while you fully charge The Delta Pro Expansion Battery from a standard AC wall outlet in 1.8 hours.
For the first time ever with a portable power station, you can charge up at thousands of EV stations worldwide. This unique charging method gives you up to 3000W fast charging on the go.
Multi-Charge delivers record-breaking speeds at 6500W. To reach 6500W, you can opt for the below charging methods.


EcoFlow Delta Pro Ecosystem:
The EcoFlow Delta Pro ecosystem stores energy day and night, reducing your reliance on the grid and lowering your energy bills by combating time-of-use rates. It integrates directly with your home using the EcoFlow Smart Home Panel.
The EcoFlow app gives you a smart breakdown of your energy habits, and you can customize your energy usage for any type of situation.
The new EcoFlow Smart Home Panel is the heart of the Delta Pro home battery ecosystem. It integrates up to two Delta Pro units with 10 home circuits. Each Delta Pro can be connected with extra batteries, solar panels, or smart generators, giving you uninterrupted power during blackouts, smart energy management for your critical loads, and lower energy bills.
With a fast 20ms switchover time, the Delta Pro and the Smart Home Panel can keep you powered on during a blackout. All the while, the EcoFlow app keeps you in the know, letting you select and modify your device priorities.


EcoFlow Smart Generator:
When the going gets tough and you’re out of charge options, get a 1800W DC fast charge with EcoFlow Smart Generator (sold separately). Just plug the generator directly into your extra battery via the port on the back. This works even when disconnected from your Delta Pro.
Compared to a traditional gas generator, the EcoFlow Smart Generator delivers less energy loss, faster charging and higher efficiency.

September 6, 2023
Are you able to stack one on top of the delta pro delta station?
1 Answer
We would not recommend stacking the units. Many people will keep them on wire shelves so that they can be above or below the other unit while not touching. Thank you for your inquiry!
