Description

The EcoFlow DELTA Pro Smart Extra Battery is a powerful expansion battery that's developed exclusively for the EcoFlow DELTA Pro Portable Power Station. Providing an additional 3,600Wh of energy storage, this add-on battery increases the total capacity of a DELTA Pro system from 3,600Wh to 7,200Wh. Connect two Smart Extra Batteries to achieve a maximum combined capacity of 10.8kWh, giving you more stored energy for home backup, caravanning, off-grid living, outdoor activities and professional use.

Once connected to the DELTA Pro, the units charge and discharge together while maintaining a balanced charge level. The Smart Extra Battery benefits from the DELTA Pro’s wide range of supported charging methods, including mains electricity, compatible solar panels, car charging, EV charging and the EcoFlow Smart Generator. When conventional charging options are unavailable, the Smart Generator can also connect directly to the extra battery for DC fast charging.

A clear front LCD screen displays the remaining battery percentage, estimated charging or discharging time, input power, output power and important system warnings. When the battery forms part of a connected DELTA Pro system, compatible information and settings can also be accessed remotely through the EcoFlow app. 

Built with durable lithium iron phosphate (LFP) battery chemistry, the EcoFlow DELTA Pro Extra Battery is rated for approximately 3,500 charge cycles before its capacity reduces to 80% of the original level.
