Description
Overview
The DELTA Pro Smart Extra Battery adds 3,600Wh to an EcoFlow DELTA Pro. One doubles capacity to 7.2kWh; two triple it to 10.8kWh. Once connected, the batteries charge and discharge together and keep the same charge level.
It charges through every method the DELTA Pro supports, including 6,500W MultiCharge. In an emergency, an EcoFlow Smart Generator (sold separately) can charge it directly at up to 1,800W DC, even when it’s disconnected from the DELTA Pro. A front LCD shows input, output, charge and time remaining.
Note: EcoFlow says this battery will not be restocked once current inventory sells out.
