Description
The EcoFlow DELTA Pro Smart Extra Battery expands the capacity of a DELTA Pro power station rather than functioning as a standalone unit, aimed at homeowners and mobile production setups that need more runtime than the base station provides. Adding one or two extra batteries scales the system up to 10.8kWh at a lower cost per kWh than buying an equivalent-capacity station outright.
- Adds 3600Wh of Capacity: Expands a DELTA Pro's storage without replacing the base unit.
- Up to 10.8kWh Total with Two Extra Batteries: Priced up to 30% lower than a single power station of the same combined capacity.
- 10-Year LFP Battery Lifespan: Rated for 3,000+ charge cycles before dropping to 80% of original capacity.
- Plug-and-Play Installation: No setup required; monitor and control the extra battery through the EcoFlow app.
- 5-Year Full Warranty: One of the more comprehensive coverage terms in the category.
