Question about EcoFlow Delta 2

The device can be used up to around 0 % of its capacity before it switches off due to excessive discharge. The usable capacity therefore corresponds to almost the full capacity of 1024 Wh, as the device has a deep discharge protection function that triggers the switch-off at a critical charge level.

An exact specification of the switch-off capacity in Wh is not explicitly stated in the available manuals, but it is common for LiFePO4 batteries such as this one to be discharged to almost 0 % before the protection takes effect. The device switches off automatically to prevent deep discharge, which protects the service life of the battery.

For precise monitoring, we recommend using the LCD screen or the EcoFlow app, which displays the charge status and warns of critical discharge.
