Why Buy From Us
Boost your EcoFlow DELTA Pro energy system with this advanced 3600Wh Smart Extra Battery. Designed for seamless integration, it expands your overall power storage for home backup, outdoor use, and off-grid applications. Enjoy reliable long-term performance with premium LFP battery technology that maintains up to 80% capacity even after years of daily charging cycles. With intuitive monitoring through the EcoFlow app and simple plug-and-play setup, enhancing your power system has never been easier.
Make it a triple.
Double or triple the capacity of your DELTA Pro to 7.2kWh or 10.8kWh. That'll give you days of power for your essential appliances.
Charge anytime, anywhere.
DELTA Pro's Smart Extra Battery benefits from all the charging methods DELTA Pro has, including 6500W MultiCharge. That means you can charge anytime, anywhere as long as your extra battery is connected to DELTA Pro. Once connected, they'll charge/discharge in unison, keeping the battery percent level across both units.
Ready for any emergency.
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.
