FAQ

What is X-Boost?

This product supports X-Boost, an EcoFlow feature that supplies power to devices with a wattage of 3000W. X-Boost ensures the device does not fail due to overload protection. When using X-Boost, DELTA Max still has a rated power output of 2400W.

Using the Smart Generator

The EcoFlow Smart Generator can charge DELTA Max (up to 1800W), expanding the capacity (up to 2x5.4kWh) and extending the power supply time. When the Smart Generator is connected to DELTA Max and battery capacity is less than 20% (can be set in the app), the Smart Generator will automatically start topping up the battery.

Charging and discharging with the Extra Battery

When charging/discharging, the BMS will charge the one with low voltage first. It will then balance the charge in the two units before charging/discharging further.

How to Upgrade DELTA Max's Firmware

1. Long press the IoT button under the screen for 3 seconds, and the WiFi icon on the screen will flash. After confirming that DELTA Max's WiFi is on, connect your phone to the unit. 2. Open the app and click the "+" in the upper right corner to add a device. Connect to the WIFI or a mobile phone hotspot. Go to the DELTA Max page, then Settings>Firmware>Update. 3. If you can't find the "Upgrade" reminder, it means that your home router is not connected. Press and hold the IoT button under the DELTA Max's screen for 3 seconds to reconnect. 4. Upgrading won't be complete if it is interrupted. Restart DELTA Max, reconnect the WiFi and DELTA Max, then update again. 5. If you can't update using the app or there is still a failure after updating, contact support.eu@ecoflow.com.

What Battery Cell Type Does DELTA Max Use?

There are 224 cylindrical lithium-ion 18650 NCM batteries used in DELTA Max, in a configuration of 16 parallel and 14 in series.
