EcoFlow DELTA 3 Max Plus Extra Battery | 2048Wh
The EcoFlow DELTA 3 Max Plus Smart Extra Battery adds 2048Wh of LFP storage to your EcoFlow DELTA 3 Max Plus, doubling total system capacity from 2048Wh to 4096Wh. Plug it into the power station's Extra Battery Port using the included cable, and the system automatically detects and manages the second battery. No setup, no configuration, no separate charger.
Built for home backup, freedom camping, motorhome power, and off-grid living, the extra battery gives you serious runtime when mains power isn't an option. Run a 65L fridge for over a week, keep essential appliances going through multi-day outages, or stay off-grid for longer without needing to recharge mid-trip.

Note: Host power station sold separately. The extra battery only operates when connected to a compatible EcoFlow power station and is not a standalone unit. Double Your DELTA 3 Max Plus Capacity
The DELTA 3 Max Plus has a standalone capacity of 2048Wh. Add this extra battery and total system capacity jumps to 4096Wh - enough to power a 250Wh-per-day camping fridge for over 16 days, or keep a router, modem, lights, laptop, and a few small appliances running through an extended power outage. The maximum AC output stays at 3000W, but your runtime doubles. Plug-and-Play Setup
No setup, no configuration. Connect the extra battery to the DELTA 3 Max Plus Extra Battery Port using the included cable, turn it on, and the power station detects and manages it automatically. Charging and discharging happen through the host power station, so you only need one AC charger, one solar input, and one app to manage the entire system. The battery icon appears
