Expanded energy storage capacity
The DELTA 3 Max Plus additional battery significantly increases the usable energy of your EcoFlow DELTA 3 Max or DELTA 3 Max Plus Powerstation. The additional capacity allows you to power devices over longer periods of time without having to refuel in between. This is particularly useful during long power outages, evening outdoor adventures or power-intensive applications such as tools, kitchen appliances or heaters.

Seamless integration into your EcoFlow ecosystem
This additional battery was specially developed for the EcoFlow system and guarantees perfect cooperation with your power station. Once connected, the system automatically detects the additional capacity, intelligently adjusts the energy flow and ensures that charging and discharging processes are carried out optimally, without manual intervention.

Intelligent energy management
Thanks to EcoFlow's advanced energy control, charging cycles, power output and battery care are automatically optimized. The auxiliary battery works dynamically with the main station to:
to enable longer running times
Maximize the life of your batteries
to improve loading and unloading efficiency
You can easily monitor system information directly in the EcoFlow app - including charge status, remaining running time and power flow.
Convenient app and connectivity control
The EcoFlow app gives you a full overview of all energy data at all times. You can view charge and discharge curves, set automatic schedules and track your energy flows in real time - even remotely. Push notifications keep you informed without having to physically monitor the power station.

Ideal addition for a wide range of applications
The additional battery massively expands the possible uses of your power station:
Emergency power supply at home: Longer protection in the event of a power failure
Outdoor & Camping: More energy for lights, cool boxes, chargers
Jobsite & Events: Stable power for tools, PA systems, pumps
Electronics & Media: Longer runtimes for laptops, TVs, routers

Robust hardware & security technology
EcoFlow uses high quality components and protection mechanisms in the additional battery, including:
Overload, overheating & short circuit protection
Intelligent cell balancing
High quality LFP cells for long life
Stable construction for frequent mobile use
